RSBW20 Sprag Freewheel Backstop One Way Clutch Bearings
It has been filled with grease at the factory and can be installed in vertical or horizontal position immediately.
Mainly used to prevent reverse rotation, this model is characterized by providing large torque in the smallest space, this type of design can be used in harsh environments, such as high humidity environments, or areas with water splashes.
The groove of the torque arm is fixed on the machine wall with screws to provide strength to prevent reverse rotation. The gap between the screw and the groove of the torque arm is 1% of the width of the groove. After the sweep arm and the bearing are installed, there must be no internal stress. (Installation When the screw cannot lock the torque arm axially, there is also a gap in the radial direction, that is, no bending stress will be applied to the bearing and the torque arm).
