Machine tool bearings

AXDR

AXDR Double row angular contact roller bearings are double-direction, screw-on precision bearing units ready for installation for applications with high rigidity requirements such as rotary tables or milling heads. The bearing absorbs both axial and radial torques and tilting moments backlash-free.
AXDR bearings feature two raceways with tilted cylindrical rollers laid out in an O-arrangement. The pressure angle of 45° is ideal in order to absorb all the forces occurring in machine tools.

Bearing structure

AXDR bearings consist of 2 rings:
Inner ring
Outer ring
The rollers are introduced via special axial filling openings in the bearing; these are sealed with a plug.
In contrast to radial filling holes, the raceway is not interrupted. This leads to accurate and smooth running of the bearings.
AXDR are filled with full complement (bearing type VX).

Applications

Due to the high design strength,
AXDR bearings are not sensitive to the surrounding construction; the bearings can be installed more easily.
AXDR Double row angular contact roller bearings are frequently used as an alternative to axial-radial bearings in rotary axes and swivel axes.
