With zero backlash (no play), there’s no motion lost when these torque limiters transfer torque, so machines move smoothly with accurate and repeatable motion. They protect your machinery if there is a jam, emergency stop, or other overload by cutting off torque when a maximum torque is reached.

Put an end to lids and doors that slam shut or fly open—install these speed limiters for smooth, controlled motion.

The input and output shafts are positioned at the same height, so these speed reducers take up less than half the vertical space as our standard right-angle speed reducers.

Mount these gears to a NEMA motor. Spur gears minimize torque loss between your motor and drive shaft, making these speed reducers more efficient than our other speed reducers.

For small machinery and tight spots, these gear boxes have 1/4" diameter and smaller shafts and a footprint of less than 2½" square.
