Product Details

Features: Axial/radial bearings YRT, YRTS and axial angular contact ball bearings ZKLDF are ready-to-fit high precision bearings for high precision applications with combined loads. They can support radial loads, axial loads from both sides and tilting moments without clearance and are particularly suitable for bearing arrangements with high requirements for running accuracy, such as rotary tables, face plates, milling heads and reversible clamps.

Areas of application: Axial angular contact ball bearings ZKLDF are particularly suitable for high speed applications with long operating duration, Figure 1. They are characterised by high tilting rigidity, low friction and low lubricant consumption.

Axial angular contact ball bearings ZKLDF comprise a single-piece outer ring, a two-piece inner ring and two ball and cage assemblies with a contact angle of 60°. The outer ring and inner ring have fixing holes for screw mounting of the bearing on the adjacent construction.
