Roller Bearings have outer and inner rings which contain bearing cage and rollers. The cage is also called separator or retainer that maintains spacing between the rollers and also holds the bearings together. A wide range of are available each with distinct designs used in different applications.
There are four major types:
Spherical – Two rings on the inner raceway that handle loads and misalignment concerns.
Cylindrical – Low thrust and high radial loads at high speeds.
Needle– Long and thin cylindrical rollers for supporting radial loads.
Tapered – Tapered outer and inner rollers and raceways to accommodate the simultaneous thrust and radial loads.
We sell precision rolling bearing spindles.

What is a roller bearing?
A rolling bearing is a bearing which carries a load by placing rolling elements (such as balls or rollers) between two bearing rings called races. The relative motion of the races causes the rolling elements to roll with very little rolling resistance and with little sliding.
A rolling element rotary bearing uses a shaft in a much larger hole, and cylinders called “rollers” tightly fill the space between the shaft and hole. As the shaft turns, each roller acts as the logs in the above example. Therefore, since the bearing is round, the rollers never fall out from under the load.
Rolling-element bearings have the advantage of a good trade-off 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.
