Mounting and Coupling
The torque is transmitted on the inner and outer ring by press fit. In order to transmit the torques specified in the table, the outer ring must be accommodated in a housing with an external diameter K. The housing is made of steel or grey cast iron in minimum quality GG-20. When using other housing materials or smaller external diameters, we urge you to contact us regarding the transmissible torque.
The tolerance of the housing bore D must be ISO R6 and the tolerance of the shaft must be ISO p5. With these fits, normal bearing clearance
is achieved in a built-in state.
The permissible operating temperature of the freewheel is - 40°C to 80°C.
