Every bearing that has a non-zero contact angle will generate an axial load as a radial load is applied. This generated load is referred to by a fe...

Tapered roller bearings can be set at initial machine assembly to any desired axial or radial clearance. This unique feature enables a designer to control bearings to meet anticipated application operating conditions, and thereby provide optimum bearing and system performance.

A reader asks: I have heard that new axles no longer need a break-in period. True or false?

Many of us have been there; the bearings had the correct preload. You know it, you were there, and you personally saw the measurements. Now, the testing is done and the preload is gone. Not a little gone, not sort of gone - gone, gone. Finger pointing ensues. Suppliers are dragged in by their wrinkly Polo collars. You know the drill. Losing preload in a tapered roller bearing (TRB) system over the life of your application can be a troublesome problem, particularly for gear sets that are prone to noise or severe applications that rely on a very rigid and stable system.

What are the best methods to adjust tapered roller bearings?

This article summarizes some common hurdles, issues and questions encountered by the newer and casual users of tapered roller bearings.
