Axial/radial bearings are double direction axial bearings for screw mounting, with a radial guidance bearing. These ready-to-fit, pregreased 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 – series YRT is generally the best suited. Where comparatively lower friction and higher speeds are required, RTC bearings can be used. For higher requirements in accuracy, these bearings are also available with restricted axial runout accuracy. For the bearing arrangements of direct drive Axes, there is the series YRTSpeed. 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.

Axial angular contact Ball bearings ZKLDF are low-friction, ready-to-fit, greased 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 suitable for precision applications involving combined loads. Their preferred areas of use are bearing arrangements in Rotary tables, milling, grinding and honing heads as well as measurement and testing equipment.

Axial/radial bearings with integral angular measuring system

Axial/radial bearings with integral angular measuring system YRTM correspond in mechanical terms to series YRT but are additionally equipped 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. The unit comprises an axial/radial bearing with a dimensional scale and a MEKO/U electronic measuring system. The electronic measuring system consists of two measuring heads and an electronic evaluation system.
