Ratchet Arm & Backstop Clutch
We can manufacture a ratchet arm clutch or indexing clutch for rotary arm actuation or backstop clutch applications.
A very economical option is our backstop clutch for your conveyor system or use this device for rotary action in conjunction with a motor, hydraulic cylinder, pneumatic cylinder, or other mechanical means.
When attached correctly, these Ratched Arm Backstop Clutches can efficiently protect valuable product from reversed torque on any incline conveyors (not allowing the conveyor to back up. Simply mount the ratched arm backstop clutch on your primary drive shaft and attach the ratchet arm end to a fixed position (see note below).
Inversely, when looking to drive through the clutch into the shaft there is no simpler and more compact indexing clutch than this. Due to an infinite number of potential engagement points on the circle (no cogs), these indexing clutches offer the ultimate flexibility in any application.

NOTE: It is recommended on the ratchet arm ends to allow at least 1/16” free play either way on the axial plane. This allows for the cam and shaft to find their true parallelism with the ratchet housing. Tightening down and restricting the ratchet housing will cause misalignment, runout and all or some of the problems formerly listed.
