Application example
Complete Freewheel BA 90 R as a backstop on the end of a transport roller. The backdriving torque is supported by the lever arm with holding pin on the base. If the holding pin is removed, the shaft can be turned in both directions.
 
Mounting
The backdriving torque is supported by the lever arm with holding pin. The holding pin engages in a slot or bore in the frame of the machine. It must have 0,5 to 2 mm play in the
axial and radial directions. If the holding pin is removed, the shaft can be turned in both directions. The tolerance of the shaft must be ISO h6 or j6. The freewheels BC R are supplied oil-filled and ready for installation. In the case of freewheels BA R, the inner ring
must be secured axially with a retainer plate. Prior to commissioning, the freewheel must be
filled with oil of the specified quality.
