WBC Tandem Thrust Bearings are optimally designed by many sets of thrust cylindrical roller bearings with inner and outer bearings (ring, washer, bush) on one way.

TandemThrust Bearings can receive heavy load in a limited space and support firmly in the direction of axis and last long with low frictional power. In addition, these bearings are moved by oil lubrication. Also thesetandem thrust bearings are used principally in gear boxes for single & twin screw extruders in the rubber and plastic industries.

Tandem Thrust Bearings tolerance of axis - F6
Tandem Thrust Bearings tolerance of housing - F7
