Torque-Limiting Shaft-to-Gear Couplings
Our hand-adjustable couplings provide torque-limiting protection for your system. In the event of excess torque, these couplings slip to protect motors and drivetrains and resume driving once the load has been reduced. You can adjust the torque level by hand without removing them from your shaft, giving you easy control over your system's torque limit.
