BSD Freewheels & Backstops

Request Information
Rexnord BSD Freewheels are typical safety devices that prevent connected equipment from damage following overloading or disruption. Freewheels allow the conversion of a reciprocating motion into a rotational motion.

Rexnord BSD Backstops ensure smooth operation of a machine part in both directions, locking retroacting torques of the driven part to the driving part in both directions.
