One Way Bearings

One way Bearings, also know as Freewheels are directional couplings, which means that the driving member rotates the driven member in one direction, while automatically disengaging itself from the driven member when the direction of rotation is reversed, the two operating states are:

  1. Transmission of torque.
  2. Idling (overrunning).
The freewheels may be employed as:
  1. Overrunning clutch, the freewheel disengages automatically when the driven member rotates faster than the driving member.
  2. Indexing clutch, the freewheel allows the conversion of reciprocating motion into rotational movement.
  3. Backstop, the freewheel allows rotation in one direction only, it overruns continuously during operation, the freewheel prevents reverse rotation if the drive is disconnected.
Two basic versions are available, the overrunning speed determines the selection of the appropriate model:
  1. Grip-roller freewheels for low to medium overrunning speeds and for indexing clutches.
  2. Sprag freewheels for high overrunning speeds and for backstops.
