Tandem Thrust Bearings M3CT420A 4x20x32mm  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 these tandem thrust bearings are used principally in gear boxes for single & twin screw extruders in the rubber and plastic industries. Tandem bearings are predominantly fitted with standard axial cylindrical roller and bearing assemblies.
