These 3.25” input to output shaft distance gearboxes are available in ratios of 10:1, 15:1, 20:1, 30:1, 40:1, & 60:1 with outputs in left hand shaft, right hand shaft, dual shaft, and hollow shaft. The 325 gearbox C-face interfaces match NEMA 56C, 145TC, and 182/4TC motor frame sizes.


Constructed of cast iron one-piece housings; the worm gearboxes are designed to change drive direction by 90 degrees, drive a load at a reduced fixed ratio of the motor speed, and increase output torque by the same ratio. 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.


Cast iron worm gearbox prices start at $157; the full line is normally available for same-day shipping and is backed by a one-year warranty. Mounting bases including a new 325 size, are available for ease of installation.
