Bearing choice

Loads

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 Load applied perpendicular to the shaft axis  Example: rolling gantry muffle

Axial load Load applied parallel to the shaft axis Example: drill

In some applications, the two loads are combined.

Combined loads Radial  load + Axial load  Example: car wheels
