A rotary table bearing arrangement ensures precision grinding according to requirements

In production of the axial angular contact ball bearing unit ZKLDF, INA was very precise, to be specific: P4 precise. This is the range for the geometrical and running accuracy of the finished bearing units. We carry out grinding in the high precision range so that you can later lap and polish in the nano value range.

A low-vibration bearing arrangement of high speed grinding and polishing tables using INA rotary table bearings will always give you benefits. The increased rigidity and precision of the overall solution due to the geometrically stable, single-piece outer ring is only one argument in favour. Other convincing arguments include advantages such as simple fitting thanks to the flange mounting facility of the inner and outer ring or the high limiting speeds.

Last but not least, there is also a cost factor you should not ignore... Our rotary table bearings are supplied with a factory set defined preload and only require simple screw mounting, without additional setting work. A comprehensively cost-effective compact solution, isn't it?
