FALMOUTH – Thursday night's MIAA Endowment Game between the Falmouth High Clippers and Falmouth Academy Mariners girls basketball teams will have absolutely no bearing waterproof rubber rings on either team's regular-season record. Nor will it affect where either team is seeded when tournament begins next week.Tell that to the two teams who battled from the opening tip to the final buzzer.Jenni DiCecco scored 15 points, including a go-ahead layup with about two minutes to play, to lead the Clippers past the Mariners, 50-45, at a packed Falmouth Academy gym last night.“When I signed on (to this game), I didn't know we'd have this atmosphere,” Falmouth High coach Bob Buscher said. “They're a good club. I wouldn't have signed on if they were a bad club.”

The Clippers and Mariners went back and forth throughout, with neither team ever leading by more than six points. Kyla Azzato's two free throws made it 43-37 Clippers midway through the fourth quarter, but Kendall Currence (game-high 20 points) got four back immediately when she took a pass from Jane Earley (eight points), buried a 3-pointer, drew a foul and converted it.“She's the real deal,” Buscher said of Currence. “She hit two or three 3s with fouls.”Falmouth Academy's Eliza Van Voorhis (10 points) knocked down a jumper from the foul line to tie the game 43-43 with 2:25 left to play, but on the opposite end DiCecco split two defenders, drew contact on a layup waterproof protective shield and hit the free throw to put the Clippers back up 46-43.Colleen Hall, one of three Mariners seniors honored on Senior Night (with Charlotte Van Voorhis and Christie Brake), hit down a jumper to cut the lead back to 1 with about 1:45 left, but DiCecco hit two more free throws to push Falmouth High to a 48-45 lead.

Currence, who'd scored 16 in the first half and hit two 3-pointers, got open in the corner for what would've been a game-tying 3-pointer, but the shot clanged off the rim. Taylor Miller (13 points, 17 rebounds) then grabbed an offensive board to keep Falmouth's possession alive, and Olivia Ferraro (13 points) hit two more free throws for the final five-point difference with 15 seconds left.“We made some mistakes in the bearing cover exporters first half with transition defense, and that's going to come up again in the tournament,” Falmouth Academy coach Gus Adams said. “To kind of get exposed was a good thing now, rather than a week or so from now. But it was a great experience, playing against a big center like Taylor (Miller) and playing against a good, solid guard like Jenni (DiCecco).”Adams said he and Buscher have already discussed future Falmouth-Falmouth Academy showdowns, though probably during the regular season instead of as Endowment Games, which cost $300.

The only downside to last night's game was Falmouth High sophomore Natalie Gagnon suffering a severe left knee injury in the first quarter.The injury came as Gagnon and a Mariner defender collided going for a loose ball. Gagnon left the game on a stretcher and then an ambulance.“I'm sick about Natalie," said Buscher. "Don't get me wrong, but we would've scrimmaged (either way). I might've lost two kids in a scrimmage. You can't worry about that.”Falmouth High will take a 15-5 into the tourney. Falmouth Academy is now 22-1. The tournament seedings and pairings will be done today.Last night's game raised approximately $3,000 for the Falmouth Service Center, whose services include a food pantry, community garden TF waterproof rubber rings and financial and housing services. Funds were raised through ticket sales, a $450 donation from Falmouth Academy coach Gus Adams – $10 per point his team scored – and an $800 donation from Falmouth to honor its eight seniors. Several bags of perishable goods were also donated.

Slew ring bearings are special types of bearings which are generally used in heavy machinery. The difference between these type of bearings and normal bearings is that, they have higher pitch value diameter, the way they are mounted on the structures, working nature which is generally "static", higher load carrying capacity, and larger number of rolling elements.

Quality System are generally selected on the basis of the static load, which is calculated using the forces for axial and radial loads coming on it as well as the tilting moment. For correct selection of the slew bearing, certain parameters such as speed, load, and operating temperature are required. There are certain assumptions which are to be considered:

1. The bearing is made from high quality material and is free from manufacturing defects.

2. Bearing is selected as per the load calculations.

3. Installation of the bearing is proper.

4. Grease used is of good quality and it reaches to every corner of the bearing.

5. Bearing is sealed using high quality seal.

6. Operating temperature of the bearing is within range.

7. Proper care for maintenance is ensured.

The conditions mentioned above, if fulfilled, ensure maximum bearing life. But, one must consider the fact that the life depends more on practical conditions and not on theoretical values.

Slew ring bearing, just like the other ball and roller bearing accessories are subject to wear and tear due to the continuous moment of the rolling elements (either balls or rollers) inside them. The bearings which can sustain the calculated hours of life operation are subject to wear which is natural. As compared to the conventional roller bearings, slew ring bearings work in relatively harsh environments where they are subjected to heavy to very heavy loads in restricted working span. Uneven load distribution, deformation in the races, proper lubrication for the rolling elements, all these parameters affect the working life of the bearings. Apart from natural wear, these conditions, if not taken care of, can considerably reduce the life of the slewing bearing.

When the slew bearing is rotating, the rolling elements are rolling in cyclic pattern over the inner raceways. Since the rotational speed is very low (mostly below one RPM), the phenomenon of gradual pitting and chipping takes place. Pitting is caused by the heavy loads on roller elements. The durability of the slew roller components who have undergone improper induction heat treatment are more prone to failure in early stages of the operating cycle. If this occurs, the bearing must be replaced or repaired immediately, as by not doing so, pitting will be more and that might result into jamming of rolling elements inside the bearing. This may also cause the ring to crack in extreme conditions, if it is not taken care of.

The causes for such failures is mainly due to the excessive over loading of the bearing. Another reason may be due to the unusual gaps between rolling elements, which may cause slackness in the bearing. This type of breakdown maybe due to the improper foundation structure on which the bearing is mounted. Similarly, if the layer which is hardened is small, the bearing will lead to catastrophic failure. The layer thickness should be properly selected on the basis of the stress which the bearing is subjected to.

In case of some slew bearings, fatigue may occur due to improper internal lubrication. In this, the surface of the raceway undergoes spalling, which results into premature wear, finally resulting into pitting. Also, if the races are not properly lubricated, there is a risk of them being corroded. This accelerates the premature wear which was already caused due to spalling of the surface.

Finally to conclude, axial play in the pressed bearing housing, especially larger diameter bearings should be taken into consideration. This is generally an important factor in case of bearings with rollers as their rolling elements, which can lead to failure. The surfaces which are induction heat treated, need to undergo strict inspection procedures to ensure there are no micro cracks in them. These micro cracks can then develop into larger cracks and the bearing fails instantaneously.The failures mentioned in these articles are generally observed failures and may not necessarily be limited to these failures only.

When slewing bearings fail, machine downtime usually leads to high costs and lost production time. Fortunately, catastrophic failures of the mechanical seals are rare. Most often, distinct symptoms indicate that bearing damage occurs long before the bearing actually fails. More important, a methodology that addresses the symptoms of slewing bearing damage should be implemented as soon as possible.

Experience has shown that damage to, and subsequent failure of, the bearing is seldom due to faults in the bearing. It is more often due to the treatment the bearing received or the use to which it was put.

The first sign of damage is frequently indicated by unusual operating behavior such as uneven running, reduced working accuracy, unusual running noises or any combination of the three. It is critical to record these early indicators, as information gained in this early period of degradation can be very useful in identifying the root cause of a problem. As the labyrinth seals becomes more damaged, root cause analysis becomes increasingly difficult.

The key to detecting early signs of a problem is effective condition monitoring. For many applications, monitoring by the machine operator is usually sufficient to detect unusual noises at an early stage. In situations where downtime is critical or hazardous, more formalized monitoring might be required, for example, assessing lubricant cleanliness and measuring slewing bearing temperature and vibration analysis.

The type of condition monitoring used depends on the experience of previous failures and the production environment in which the bearing is used. the Bearing damage can generally be classified as localized or widespread. The first is usually restricted to specific locations on the plastic seals. This can take the form of indentations caused by rolling elements, corrosion or fractures. It can be recognized most easily using a combination of vibration and lubricant monitoring. Vibration methods reliably detect fatigue damage at any early stage but are not suitable for detecting lubrication problems.

Widespread damage is often the result of an insufficient supply of clean lubricant. Failures of this type can be detected by monitoring the lubricant supply. Oil flow can be monitored for pressure, flow and cleanliness. A magnetic plug in the lubricant supply system gives a crude indication of lubricant condition, while a spectrophotometric or ferrographic analysis can be used to provide a more precise check.

Temperature can be monitored using thermocouples and gives a very reliable indicator of impending bearing problems. Normally a system reaches a steady-state temperature and shows a sudden rise when there is a lack of lubricant. The temperature typically rises unevenly over time if the grease is deteriorating.

When a damaged flanged bearing housing has to be removed, the cause must be established to avoid future failures. Inspection of the bearing alone is not usually enough to pinpoint the precise cause of damage.The rarely mentioned aspect of this fun and mischief as demonstrated in Tom Peter's example and my own is that by bringing a little bit of herself to the job it also makes it a more energising and satisfying role for the housekeeper.

People like to know they are being looked after by real people who care. The systems and standards within an organisation, free workers up to, in the right way, put a bit of personality into their role, however humble that role may be.

It would be worth sharing these examples with your team and asking (not telling) them what they have done or would enjoy doing to make the experience memorable for their customers.


The sliding bearing, also known as a journal or sleeve waterproof rubber rings, is a plain shell bearing that is used to support rotating shafts or journals. These bearings are anti-frictional and have a cylindrical or semi-cylindrical bushing made from a suitable, soft material. They are generally classified into full, partial, and fitted bearings depending on the extent to which the bearing envelops the journal. A Babbitt bearing is any journal or shell bearing that is coated with a layer of Babbitt material on the contact surface. Some typical applications of journal and Babbitt bearings include automotive engines like connecting rods and crankshaft that offer high temperature, speed, as well as varying load.

An integral part of designing a bearing is selecting the material, since the bearing materials constitute an important part in the journal bearing. This maxim is particularly important for Babbitt bearings. The materials that are chosen are especially significant when considering the beginning of the hydrodynamic lubrication process, when contact occurs between the rotating shaft and the waterproof protective shield. The bearing materials must be soft enough to resist the wear and endure load under gas pressure. In addition, they must also possess good compressive and fatigue strength. While the compressive strength is to withstand the temperature variations, the fatigue strength is to resist cyclic loading of the journal when it is revolving. Finally, the material should also have a low shear strength aimed at easy smoothing of surface asperities.

Some other important considerations of the bearing materials include a low coefficient of friction, reliability, and resistance to corrosion. In addition, they must also have good thermal conductivity to dissipate the frictional heat. Considering all these requirements, Babbitt alloys are one of the most commonly used bearing materials.The role of a bearing is to provide relative positioning and rotational freedom while transmitting the load of the shaft to the bearing housing. The factor, which controls the length of the bearing to journal diameter, is known as the L/D ratio. When this ratio is greater than unity, it results in a long bearing, while a ratio less than unity would result in short bearings.

The deflection produced by the journal within the bearing can adversely affect its load carrying ability. This deflection can be greatly reduced by increasing the diameter and decreasing the length of the journal. The resultant short bearing cover exporters has a greater flow of oil at the ends, which helps in transferring the heat from the bearing and consequentially reducing the bearing's temperature.

The load carrying ability of the bearing can be increased by reducing the roughness of the sliding surface. A good quality finish and minimum clearance can ensure that the load carrying capability of the bearing is maximized. However, the clearance should not be too small, as it would result in higher bearing temperatures and reduced film thicknesses. Surface treatment also improves the bearing design.Most Babbitt bearings are operated as hydrodynamically lubricated bearings and the design considerations for hydrodynamic bearings are significant as well. To ensure minimized friction and bearing wear, the bearing material for hydrodynamic bearings should have moderate shaft deflection and adequate strength at operating temperature conditions. At the hydrodynamic bearing inlet, there must be continuous and adequate supply of clean and cool oil.

Additional grooves can be machined into the bearing for easy distribution of oil that covers the whole journal. The appropriate combination's of clearance and oil viscosity for any hydrodynamic operation condition should be chosen correctly by taking into consideration the load and time elapsed during start-up and shutdown process. Two other important considerations for designing hydrodynamic TF waterproof rubber rings include the heat dissipation and friction. The lubrication systems should be set up such that lowest temperatures for the bearings are achieved with minimum oil film thickness. Similarly, friction should be kept as low as possible to refrain from power loss.

Not everyone gets his or her daily supply of natural vitamins and minerals from fruits and vegetables. Because of a busy schedule, one may often skip meals or have a quick bite of something not so healthy, as a chocolate bar. This unhealthy eating habit is the usual resort steel housing of those children or adult that has a hectic time schedule at work or in school. Although some foods may provide an instant supply of energy, this mental alertness does not stay for long. It is still very important to eat fruits and vegetables every day.

These food items contain essential vitamins and minerals that the body needs. These nutrients from fruits and vegetables help fight stress, thus preventing illnesses. These also give anyone more vitality that lasts for hours, instead of the sugar rush that those who ate chocolates bearing housing might feel. Fruits and vegetables also contain phytochemical that helps maintain good health by keeping viruses away.

As ideal as it may be to follow such kind of diet, it may be quite difficult because of a busy schedule. However, there is one solution to receive a daily dose of natural vitamins and minerals, while keeping up with the rush at work or school. Instead of eating a fruit or vegetable, one can simply juice these food items. By gulping down the nutrients in these food items, you get to stay in shape and in perfect health - the convenient and efficient way.

When making a glass of fresh juice, it is important to look for a quality juicer that can do the job well. A stainless steel juicer is the most ideal because it offers more benefits than a plastic juicer. Juicers that come in stainless steel housing and parts are definitely more reliable when it comes to their performance and durability. Juicer parts made from steel are less likely to break, as compared to those crafted from plastic. Stainless steel parts do not tarnish, stain or rust. Juicers that have plastic parts tend to look yellowish in time, particularly the ones that come in white colour. The stain from fruits and vegetables are very difficult to remove from juicer parts made from plastic. Thus, the overall appearance of a stainless steel juicer is much better because it is stain-free and has a natural gleam.

Stainless steel juicers are easier to clean. This type of construction does not absorb stains or smell, thus anyone will have a much easier time cleaning the parts. The parts are also easy to disassemble, and are dishwasher-safe. Moreover, these parts assemble easily after clean up. Because of the hassle-free clean up, stainless steel TF bearing components juicers are easy to maintain. This type of juicer is definitely more efficient to use - from start to finish.
