Aluminum IronHorse worm gearboxes are available in five frame sizes from 30 mm to 75 mm, with gear ratios from 10:1 to 100:1. Constructed of aluminum alloy housings, they are designed with a C-flange input and hardened hollow-bore output shafts. They feature double-lipped embedded oil seals to prevent leakage, epoxy paint inside and outside the reducer to prevent corrosion and double bearing sets on both shaft ends. Designed to change drive direction by 90 degrees, the gearboxes are mountable in any direction except motor pointing up.
