AV55 54MM Backstop Clutch Bearing
Technical Datas
Type AV 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.
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. 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. 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 AV type ideal for light indexing applications.
