Slewing ring bearing

Benchtop horizontal digital video comparators; Direct-drive spindle CNC machine.

iglide polymer slewing ring bearings (PRT) have sliding elements between the inner and outer bearing rings made of aluminum or stainless steel. Maintenance-free sliding elements made of iglide J plastic minimize friction and wear without lubrication. The high-performance plastic withstands up to 35MPa surface pressure. Electrostatic discharge (ESD)-compliant versions are available.

The PRT-04 range of slewing ring bearings for medium loads is 50% smaller in installation height, 60% lighter, and can reduce costs up to 20%. They are suitable for automation, stage technology, and control panels.

PRT-04 slewing ring bearings are available from stock with inner diameters of 50mm to 300mm. Accessories include drive pin, variable rotation limit, and toothed ring up to the clamping lever.

Test data incorporated in the iglide PRT slewing ring configurator allows users to select the proper slewing ring bearing and calculate the application’s service life.
