Types of Bearings

Rolling-Element Bearings

There are several types of rolling-element bearings. These bearings make contact by some small rolling element such as a ball or cylinder. Below are common rolling-element brearings and their cross-section designation.

Sliding Bearings

One type of sliding bearing is a pillow block bearing. These bearings allow for misalignment of shafts, but have smaller load ratings than ball bearings.
