Crossed-roller slewing bearing 11-Serie

We manufacture the cross-roller slewing bearings of the 11-series with raceway diameters up to 5,000 mm and roller diameters of 80 mm. They have a single-row roller raceway angled at 45° and are characterised by a permanent torque resistance at different loads and a higher dynamic lifetime compared with equivalent ball slewing bearings.

Besides ball bearing slewing rings the crossed-roller place also higher requirements at the stiffness and accuracy of adjacent construction.

Applications:
Robots, antennas, medical technology, machine tools, positioning equipment, filling machines, packaging machines.
