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.

Ball Bearing Preload - GMN Bearing USA

A manufacturer calculates factory preload from the axial offset value (or clearance) between the inner and outer ring. It’s usually labeled as light, medium, or heavy (strong). Factory Preload Example Using our GMN S6005 C angular contact bearing as an example, it has an axial offset increase of 5 microns from a light to a medium preload.

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.

Stiffness analysis of angular contact ball bearing under non-uniform preload …

Reasonable bearing preload can sufficiently ensure the good performance of bearing. Traditionally, rigid and constant preloads are used to apply uniform forces on the bearing. However, considering the machining errors, assely errors and load conditions, the uniform preload actually manifests as a non-uniform load distribution in ball bearing. The work …
