TORQMASTER OVERRUNNING CLUTCH YOKE

55 Series Torqmaster Overrunning Clutch Clamp Yoke

55 series torqmaster overrunning clutch yoke with 1 3/4-27 spline bore and clamp connection

The Friction clutch is indispensable in certain agricultural implement applications. The friction clutch is the only torque limiter that has the ability to continuously transmit power (at a reduced level) while overloaded. This is valuable during startup of high inertia machines, as well as for leveling out torsional fluctuations due to high cyclic loads. The TorQmaster’s patented technology dissipates heat quickly, improving durability while protecting the machine. The TorQmaster clutch packs are preset for various power levels to meet the needs of the application while reducing torque overloads on the implement, n adjustment is required after slipping. The free-motion design allows for easy connection of the PTO Drive Shaft to the tractor PTO, the overrunning design adds to this also the ability for any implement to free-wheel to a stop. The TorQmaster overrunning clutch yoke must be used in conjunction with a mating TorQmaster overrunning Clutch and is easily mounted with standard tools.
