Slewing rings

Slewing rings or slewing rings

Slewing rings (also known as slewing rings, slewing bearings or swivel bearings) are connecting elements for transmitting rotary movements with a high load-bearing capacity. These bearings usually have to transmit very high axial forces and absorb tilting moments. Typical applications include excavators and cranes, but also machine tools, etc.

ZYS Slewing Rings - Quality at the top price

Fröhlich & Dörken offers a wide range of slewing rings - also called turntables. Slewing rings are as diverse as their applications. The raceway system and the toothing play a decisive role. The type of toothing is differentiated into untoothed, external toothed and internal toothed. The size of the rolling elements and the running circle diameter are also decisive. As a ZYS contract partner, we are your contact in Germany. The various ZYS slewing rings are presented below.
