New selection curves for four contact point slewing bearings
Published online on April 20, 2015
Abstract
The selection of slewing bearings is based on the static load-carrying capacity. In this sense, manufacturers provide selection curves in their catalogues. However, little information is given about their origin. This work develops new and more versatile selection curves for four contact point slewing bearings, with a clear explanation of their background, scope and limitations. The new curves take into account the two possible static failure types, the ball-raceway contact failure and the bolted joint failure.
