Introduction of cylindrical roller thrust bearing
A cylindrical roller bearing, also known as a rolling bearing,is a bearing which carries a load by placing rollers between two bearing rings. The relative motion of the pieces causes the round elements to roll with very little rolling resistance and with little sliding.
One of the earliest and best-known rolling-element bearings are sets of logs laid on the ground with a large stone block on top. As the stone is pulled, the logs roll along the ground with little sliding friction. As each log comes out the back, it is moved to the front where the block then rolls on to it. It is possible to imitate such a bearing by placing several pens or pencils on a table and placing an item on top of them.
A rolling element rotary bearing uses a shaft in a much larger hole, and cylinders called "rollers" tightly fill the ***ce between the shaft and hole. As the shaft turns, each roller acts as the logs in the above example. However, since the bearing is round, the rollers never fall out from under the load.
Rolling-element bearings have the advantage of a good tradeoff between cost, size, weight, carrying capacity, durability, accuracy, friction, and so on. Other bearing designs are often better on one specific attribute, but worse in most other attributes, although fluid bearings can sometimes simultaneously outperform on carrying capacity, durability, accuracy, friction, rotation rate and sometimes cost. Only plain bearings are used as widely as rolling-element bearings.

introduce cylindrical thrust roller bearing
Thrust roller bearings are used to axial load mainly axial, radial joint load, but the radial load should not exceed 55% of the axial load. With other thrust roller bearings, such bearings friction coefficient is l |
