New IronHorse inline gearboxes with cast-iron frames use helical gears to provide quiet startup and smooth operation. These gearboxes utilize C-face motor mounting interfaces and the universally interchangeable compact design ensures easy OEM replacement.

Five gearbox frame sizes are available for NEMA motor frame sizes from 56C up to 254/6TC. Six gear ratios are available from 5:1 to 60:1 and the helical gearboxes are sized to handle motors from 1 to 20 hp.

​IronHorse helical gearboxes have a one-piece FC-20 cast iron housing and 1045 carbon steel shaft. Heat-treated and ground high-strength steel gears are AGMA Class 10 rated. Heavy duty bearings are used on the output shaft and an interior channel guides oil to constantly lube the bearings; double-lipped embedded oil seals prevent leakage. IronHorse helical gearboxes start at $360.00.
