TORQUE LIMITING DESIGN
Features + No external parts to align, assemble, or adjust for easy installation. + Pre-set to your torque limit for reduced installation time. + Clutch slips automatically to reduce costly downtime and shock damage. + When overload is removed the reducer returns to normal operation without having to reset the clutch. + Internal slip clutch runs in oil bath for longer life, rust prevention and less maintenance. + Lifetime torque setting eliminates the need for frequent adjustments. + Easily adjusted in the field, eliminating the need for factory re-calibration.
