Relation Among Bearing Preload, Rigidity and Bearing Life

1.      Background

Most customers would like to know the expected rigidity and bearing life before finally choosing TPI bearings. For such circumstances, TPI provides a unique application to evaluate customer' s needs.

2.      TPI Bearing Analysis System

By filling in bearing type, bearing arrangement, rotating speed and assembly condition etc., rigidity and bearing life can be easily calculated. The calculation will be shown in charts as Fig.1 and Fig.2. Customers can adjust bearing preload according to these charts for the expected rigidity and bearing life.
