Backstops (NRT) Operations the world over rely on Rexnord for instant-response, no slip backstops. External backstops provide more system holding power than any other backstop and increase the safety and reliability of your equipment by preventing reverse rotations.

Backstop clutches ensure better performance and lifespan for heavy-duty conveyance equipment by preventing roll back from the drive shaft. The BS-F series of clutches from Tsubaki offers reliable performance and a long service life. Contact us today to find the right BS-F series clutches for your equipment.

This not only protects the motor from rotating in reverse, it also prevents the conveyor from rolling backwards in the event of a stop due to a power failure, regular maintenance work, or an emergency situation.

Conveyor system backstops are industrial devices that are designed to protect inclined conveyors from the dangers of gravity-accelerated reverse runaways. Backstops are designed to be used as a safety mechanism to prevent roll-offs or catastrophic system failures.

Cam Clutches are precision devices, which locks the inner and outer races, through the wedging action of cams, to transmit torque in one direction of rotation and overrun in the opposite direction. These units are often referred to as freewheels, sprag, overrunning, indexing, backstops or one-way clutches, depending on their application.

2019年1月31日 · Also known as anti-runback devices or holdbacks, backstops keep the belts from running in reverse when they’re moving product on a conveyor. In addition to their role on incline conveyors, many operators choose to equip flat conveyors with backstops as well.

Inclined conveyors require an anti-runback device to prevent reverse movement of the belts. Such a device is referred to as a backstop, or holdback. Though backstops are most likely to be found on inclined conveyors, they are also employed on flat, overland conveyors to avoid the unusually severe shock loading on start-up where the loaded belt ...
