1、Type WRW is a FDC sprag type freewheel. It is bearing supported, centered plain bearings for low rotational speeds.
2、Unit is delivered grease lubricated ready for installation in either a horizontal or vertical position.
3、Primarily used as a back stop. this type provides a high torque capacity with a minimum space uirement. The design allows installation in difficult environments such as high humidity or water splash areas.
4、A bolt, secured to a fixed part of the machine and passing through the solt in the torque arm, provides the rotational stop. Radial clearance on this bolt should be equal to 1％ of the solt width. The torque arm and the bearings must not be prestressed.
