Rolling Bearings Overview

Roller Bearings contain cylindrical rolling elements instead of balls as load-carrying elements between the races. An element is considered a roller if its length is longer than its diameter (even if only slightly). Since they are in line contact with the inner and outer races (instead of point contact as in the case of ball bearings), they can support greater loading.

Rolling Bearings are also available in various types. The appropriate type may be selected after considering the type and magnitude of loading, service conditions, and the possibility of misalignment among other factors.

Rolling Bearings Advantages

Low friction
Easy maintenance
Can take high radial loads
Tapered roller bearings can withstand high axial loads
Great accuracy
Used to adjust the axial displacement
