Rotary table bearings

INA solutions for rotary axes

The Schaeffler Group has an excellent selection of geometrically interchangeable rotary table bearings available.

The individual series start with the well-proven YRT series for standard applications such as indexing tables and swivelling milling heads, where lower speeds and short operating periods and demands for high rigidity and low maintenance prevail. The RTC series covers the high precision sector and is the right choice for applications with demands for concentricity and highest axial runout accuracy. The double row angular contact ball bearing series ZKLDF is foreseen for highest speeds and long periods of continuous use. ZKLDF bearings are particularly suitable for grease lubrication.


Performance highlight of the range is the series YRTSpeed (M) which was specially developed for axes with direct drive technology. High speed range combined with bearing rigidity are its special characteristics. Additional technical benefit provides the integrated measing system for the precise recording of the trigonometric position.
