| Product Description | Stop reverse motion in its tracks. These sprockets use a clutch to transfer torque in one direction and spin freely in the other. They're often used for backstopping, indexing, and overrunning. For example, in two-speed systems, they connect the low-speed motor to the main drive. When the high-speed motor takes over, they stop transferring power and spin in the opposite direction. All are made in the U.S. Steel — Steel is strong, but best for dry environments since moisture will cause it to rust. Finished Bore — Mount these sprockets onto your shaft and secure with a set screw— no machining required. |
