Bearing choice


A load is a force applied to the bearing. The application, and hence the load applied to the bearing, determines the type of bearing used. Bearing qualities differ.

There are two types of load:

 Radial load applied on a bearing   

Radial load
Load applied perpendicular to the shaft axis 

Example: rolling gantry muffle


Axial load applied on a bearing  

Axial load
Load applied parallel to the shaft axis

Example: drill


In some applications, the two loads are combined.

 Combined loads applied on a bearing  

Combined loads
Radial  load + Axial load 

Example: car wheels
