Product description:

• Type AV is a roller type freewheel
• It is self-contained, centred 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

• The roller design makes the AV type ideal for light indexing applications
