If the freewheels are used for backstop applications, the number of overspeed rotations can normally only be performed by the internal component. In this case, the maximum number of overspeed rotations shown in the following pages must be adhered to and, to ensure good lubrication, a low viscosity oil should be used, preferably oil circulation lubrication.
Backstop allows the rotation in only one direction. During the work the backstop works continuously free. The backstop prevents reverse rotation if the drive is disconnected
