Rugged Worm Gearboxes

The gearboxes come in four frame sizes, and six gear ratios from 5:1 to 60:1. The gearboxes have double-lipped embedded oil seals to prevent leakage and a universally interchangeable compact design for easy OEM replacement. The main gear is constructed of an aluminum bronze casting, which is harder than typically used phosphor bronze. A one-piece output shaft hub is designed to secure the heavy-duty output shaft bearing, and double bearing sets are on both shaft ends. The gearboxes are well-suited for reducing output speed in electric motors, increasing torque, changing drive direction, or running two loads from one motor. Prices start at $130.
