Ball Detent Torque Limiters

WFSC ball-detent torque limiters (safety clutches) transmit torque backlash-free for their entire service life — compact, easy to adjust, low inertia. On overload the balls cam out of their detents and the unit slips; a signal ring can trip a switch to cut power and protect the machine. For servo / stepper and other high-dynamic precision drives needing overload protection. 8 sizes; L / M / H trip-torque stages cover 4–2400 N·m.
