IronHorse cast iron worm gearboxes (worm gear speed reducers) are mechanical power transmission drive components that can drive a load at a reduced fixed ratio of the motor speed. The IronHorse worm gearbox line now includes left hand shaft models 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. Designed to change drive direction by 90 degrees, worm gearboxes are used when space is at a premium, such as for conveyors, or to simplify mechanical design. IronHorse gearboxes are mountable in any direction, except motor pointing up. Prices start at $147; the full line is normally available for same-day shipping and is backed by a one-year warranty. Worm gear reducer mounting bases are also available for ease of installation.
