Air-Powered Torque-Limiting Shaft Couplings
For Round Shafts
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.
