Slewing Rings and Turntable Bearings Selection Guide

Slewing Rings and Turntable Bearings Information. Slewing rings and turntable bearings can accommodate axial, radial and moment loads. They are not housed or mounted on a shaft, but are instead mounted directly to a seating surface. The inner and outer rings are supplied with mounting holes and often include internal or external gears.

Modelling the Contact between the Rolling Elements and the

In slewing bearings, a great nuer of contact pairs are present on the contact surfaces between the rolling elements and raceways of the bearing. Computations to determine the load of the individual rolling elements, taking into account the flexibility of the bearing ring, are most often carried out using the finite element method.
