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