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.

The primary function of a one-way backstop clutch is to allow overrunning in one direction while preventing it in
the other. This behavior is achieved through the design of the roller or needle bearings:
Overrunning Direction: In the direction in which the clutch is intended to transmit power, the roller or
needle bearings can roll freely between the inner and outer races. This allows the inner and outer races to rotate together with minimal friction.
Locking Direction: In the opposite direction, the roller or needle bearings become wedged or locked between the inner and outer races when subjected to torque. This prevents the inner race from rotating faster than the outer race, effectively blocking any reverse motion.
One-way backstop clutches are versatile devices used in a wide range of applications where unidirectional power transmission is essential. Here are some common applications:
One-way backstop clutches are used in conveyor systems to prevent backward motion when the conveyor needs to stop suddenly. This enhances safety and prevents product damage. It is widely used on conveyor system of Grain Silo Equipment.
One-way backstop clutches are employed in the freewheel mechanism. Backstop to Prevent Reversal of Inclined Conveyor and Vertical Bucket Elevators .
With the drive at one end of the drive pulley shaft, the backstop should be located at the opposite end, away from the speed reducer and coupling.
Various industrial equipment, such as packaging machines, printing presses, and textile machinery, use one-way backstop clutches to prevent reverse rotation and safeguard against unintended backdriving.
Proper operation and maintenance are crucial for ensuring the longevity and performance of one-way backstop clutches. Here are some operating instructions:
Ensure that the clutch is installed in the correct direction, allowing free rotation in the intended direction of power transmission.
Verify that the inner and outer races are properly aligned with the respective machine components.
Apply the recommended torque to secure the clutch in place, following the manufacturer's guidelines.
The Torque Arm cannot be tightly fixed, must leave 3-5mm space to make it function well
Use the recommended lubrication specified by the manufacturer. Insufficient or improper lubrication can lead to premature wear and failure.
Regularly check and maintain the lubrication to ensure that the clutch operates smoothly.
Periodically inspect the clutch for signs of wear, damage, or contamination.
Follow the manufacturer's recommended maintenance schedule to replace or repair worn or damaged components.
Avoid subjecting the clutch to torque loads beyond its specified capacity, as this can lead to damage or failure.
Ensure that the clutch is appropriately sized for the intended application to prevent overloading.
One-way backstop clutches are essential components in various mechanical systems where unidirectional power transmission is critical. They operate on the principle of allowing motion in one direction while preventing it in the other, making them invaluable in applications like conveyors, bicycles, ratchet mechanisms, and industrial equipment. Popular models from manufacturers offer different features to suit diverse needs. To ensure the optimal performance and longevity of these clutches, proper installation, lubrication, inspection, and maintenance are essential. By following operating instructions and best practices, users can maximize the reliability and efficiency of their one-way backstop clutches.
