IronHorse™ Worm Gearboxes Now Available From AutomationDirect®

AutomationDirect has expanded its mechanical power transmission product line to include worm gearboxes in four frame sizes and six gear ratios from 5:1 to 60:1. Constructed of cast iron one-piece housings, the worm gearboxes feature a C-flange input and carbon steel shaft with either right-hand or dual shaft output.

Manufactured by one of the world’s leading gearbox suppliers, IronHorse worm gearboxes have double-lipped embedded oil seals to prevent leakage. Designed to change drive direction by 90 degrees, IronHorse gearboxes are mountable in any direction, except motor pointing up. The universally interchangeable compact design ensures easy OEM replacement.

The main gear is constructed of an aluminum bronze casting, which is much 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.

IronHorse worm gearboxes are ideal for use with electric motors for reducing output speed, increasing torque, changing drive direction, or running two loads from one motor. Optional mounting bases are also available.
