Bearing Preload | National Precision Bearings
Bearing Preload is an axial or thrust load applied to a bearing that removes excess play. There are many ways to apply preload, as well as many benefits and potential problems with preload. This article will provide an overview of bearing preloading in common radial and angular contact ball bearing appliions.
What is Preload?
7/4/2016· Radial preload on angular contact bearings is a function of shaft and housing dimensions. At HST we often restore worn or damaged bearing journals to ISO specifiion. There are several ways to achieve axial preload:Radial Preload for roller bearings can be difficult to set and this is especially true if the spindle uses straight bore roller bearings.
