Hollow Shaft Gearheads are right angled, flange-mounted gearheads that use worm gears and special helical gears. They are locked with a torque arm when mounted so the gearhead does not rotate from the reactive force of the load. It has a peak torque rating of 7,450 in-lb and a peak radial load capacity of up to 1,798 lbs. These are used in induction motors, reversible motors, electromagnetic brake motor, speed control system and synchronous motors.
