As broad as the areas of application of slewing bearings are, their individual designs are equally diverse.

As the leading manufacturer of slewing bearings, our aim is to create solutions and manufacture products that have an above average service life, even while being subjected to harsh operating conditions.

How Does a Slewing Bearing Work

A slewing bearing, also known as a slewing ring, is a machine element that absorbs all axial and radial forces and the resulting tilting moments, in a single, self-retaining and ready-to-install bearing unit.

The goal is to quickly and easily transfer the forces acting on the slewing bearing to the adjacent structural machine elements. The overall design of the product, including the inner and outer rings, the gear cutting, rolling elements and mounting holes, enables it to transmit the applied loads and allow smooth rotation at the same time while maintaining a compact footprint. Slewing bearings enable and facilitate the rotational motion of wind turbines, excavators, cranes and tunnel boring machines, just to name a few. The slewing bearing offers many advantages compared to other solutions, including taking up significantly less space, weighing less and being more cost-effective in most cases.

The Production Process –
