CR/BW and BV Series backstop clutches incorporate a torque arm with slot to engage with a bolt fixed to machine frame. Units are greased for life with labyrinth seals ideal for dust laden environments. Units can be mounted on horizontal or vertical shafts, and are available with bore range 20mm to 120mm with torque capacity to 18,450 Nm.
CR/BW Series backstop clutches use sprags to provide a high torque capacity, at low unit cost. Bearing support is plain metal bushes with seals selected to retain grease and exclude dust and moisture.
CR/BV Series backstop clutches employ roller ramp principle for extended wear life and faster operating speeds. Sealing is by shield protected labyrinth seals. Can be used for slow speed indexing.
