Hilliard Overrunning clutches are used to transmit power between a shaft and a gear, sprocket, sheave, or pulley mounted on the clutch or to directly connect two shaft ends. The roller type clutch construction is one of the oldest over-running or free wheeling designs.

An integral part of many Hilliard motion control products is their roller-ramp design. The use of hardened cams and precision-machined rollers, and outer member maximizes service life.

There is almost no wear during free wheeling operations because rollers are free to rotate between the outer member and inner cam. When the rollers are engaged, the load falls at random positions on the rollers. the result is superior service life and reliability. The MTR is similar to the MT design except the cam surface is reversed allowing it to be used in multi-speed/dual drive applications.
