GV50 Backstop Clutch Overrunning Clutch One Direction Cam Clutch Roller Bearing GV Series
Features
Type GV is a roller type freewheel. It is self-contained, centered by plain bearings for low rotational speeds, and sealed using shield protected metallic labyrinth seals.. This design is suitable for use in difficult environments. A bolt, secured to a fixed part of the machine and passing through the slot in the torque arm, provides the rotational stop.
Unit is delivered grease lubricated, ready to install in a horizontal or vertical position. Primarily used as a backstop, the torque capacity is high for a minimum space requirement.
Radial clearance on this bolt should be equal to 1– 3 % of the slot width.The torque arm and the bearings must not be prestressed. The roller design makes the
GV type ideal for light indexing applications.
