Air-Powered Torque-Limiting Shaft-to-Gear Couplings
Often used in automated systems, these couplings are both air actuated and remotely adjustable, so you can adjust the torque setting even during operation. In the event of excess torque, they slip to protect motors and drivetrains, and then resume driving once the load has been reduced.

Air-Powered Torque-Limiting Shaft Couplings
Often used in automated systems, these couplings are air actuated so you can adjust the torque during operation. In the event of excess torque, they slip to protect motors and drivetrains, and then resume driving once the load has been reduced. You can adjust the torque level without removing them from your shaft.

Heavy Duty Air-Powered Winches
for Wire Rope—For Lifting
These winches operate longer and require shorter breaks than standard air-powered winches. Because they run on compressed air, they give you longer operating times than electric winches. They have an automatic brake that holds the load when the motor stops. To lift, mount winches above the load, or use winches with a pulley that’s mounted above the load. Enclosed gears offer protection from dirt and debris.
For wire rope, see Wire Rope with Hook for Winches.
Note: Capacity is highest for the first layer of rope (at least five wraps of rope on the winch) and decreases as each additional layer of rope is wound on the winch.
Warning: Never use to lift people or items over people.
