Axial/radial bearings---Rotary Table Bearings
Axial/radial bearings are double direction axial bearings for screw mounting, with a radial guidance bearing. These ready-to-fit,greased units are very rigid, have high load carrying capacity and run with particularly high accuracy. They can support radial forces, axial forces from both directions and tilting moments free from clearance. The bearings are available in several series. For applications with low speeds and small operating durations, such as indexing tables and swivel type milling heads, the most suitable bearings are generally series YRT and YRTC.
For the bearing arrangements of direct drive axes, there is the series YRTS. Due to their high limiting speeds and very low, uniform frictional torque across the whole speed range, these bearings are particularly suitable for combination with torque motors. For higher accuracy requirements, these bearings are also available with restricted axial and radial runout accuracy.
Axial angular contact ball bearings
Axial angular contact ball bearings ZKLDF are low-friction, ready-to-fit, pregreased bearing units with high accuracy for very high speeds, high axial and radial loads and high demands on
tilting rigidity.Axial angular contact ball bearings are particularly suitablefor precision applications involving combined loads. Their preferred areas of use are bearing arrangements in rotary tables with a main
spindle function, for example in combined milling and turning, as well as in milling, grinding and honing heads and in measurement and testing equipment.
Axial/radial bearings with angular measuring system
Axial/radial bearings with angular measuring system YRTM and YRTSM correspond in mechanical terms to series YRT and YRTS, but are additionally fitted with an angular measuring system. The measuring system can measure angles to an accuracy of a few angular seconds by non-contact, magneto-resistive means.
