Applying Large Multiload Bearings to Rotating Structures

Increasing numbers of large diameter bearings are being used in turntable-type applications, replacing earlier roller and track and spindle arrangements. This paper aims to acquaint design engineers with the current state-of-the-art in the use of these bearings, with special reference to application in power cranes and shovels, gun turrets, aerial basket devices, utility derricks, and the like.

Features of various style bearings are discussed.

The equipment designer is provided with guideposts for selecting bearings and for designing suitable bearing mountings.
