Overload-Protection Spring-Loaded Torque Limiters
Protect your machinery if there is a jam, emergency stop, or other overload by cutting off torque between shafts when a maximum torque is reached. These torque limiters automatically resume transmitting torque once it drops below the set maximum. They should not be used in applications that frequently exceed the maximum torque. Since they come factory-set to a maximum torque, there’s no adjustment required and no risk of unintended changes to the torque setting.
They act as a flexible shaft coupling, so they reduce vibration and protect components from wear by compensating for angular and parallel misalignment. Fasten to your shafts by tightening the set screws, which bite into each shaft to hold it.
Sensor rings help you detect an overload by moving only when the limiter is transmitting torque. Use a sensor (not included) to trigger an alarm or shut down when the ring stops moving.

Adjustable-Height Floor Locks
Set these floor locks to the height you need to compensate for uneven and sloped floors. Use them to stabilize carts, trucks, workbenches, and other mobile equipment during loading and unloading. Floor locks bolt to the underside of your equipment and have a spring-loaded base with a nonskid floor pad to keep equipment stationary.
Note: Floor locks are not load rated. They are designed to brake your equipment in place, not lift it off the floor.
