Q: What life expectancy do bearings have for my application?

A: The exact calculation of life expectancy of a ball bearing and bearing system take a lot of effort, and is influenced by a number of factors, including:

Size of frame

Bearing play

Lubrication (oil or grease)

Temperatures on the components

Production tolerances and connection dimensions of the external components

RPM

The probable life of a bearing can be determined using the material fatigue under defined operating conditions.
