food extruder gearbox tandem bearing factory T3AR420 4x20x32mm
Tandem bearings T3AR420 consist of several axial cylindrical roller bearings arranged in line, A system of rings and washers matched to each other ensures that all stages of the tandem bearing are subjected to uniform load at all times irrespective of the ratio C/F. The rings and washers are made from hardened steel. Tandem bearings are predominantly fitted with standard axial cylindrical roller and bearing assemblies. The thrust cylindrical roller bearing T3AR420 with size 4x20x32mm, the inner diameter:4 mm, the outer diameter:20mm, the total height:32mm

Tandem bearings consist of several axial cylindrical roller bearings arranged in line, Figure 1. A system of rings and washers matched to each other ensures that all stages of the tandem bearing are subjected to uniform load at all times irrespective of the ratio C/F. The rings and washers are made from hardened steel. Tandem bearings are predominantly fitted with standard axial cylindrical roller and bearing assemblies. Figure 3, page 3, shows the power flow in a tandem bearing.
