IronHorse line of motor products includes helical gearboxes said to provide quiet startup and smooth operation in applications such as conveyors, packaging machines, and rotary tables. For use with 1- to 20-hp electric motors, the gearboxes have C-face to TC-face inputs, inline outputs, and are available in five frame sizes from 56C to 254/6TC with six nominal ratios of 5:1 to 60:1. Constructed of FC-20 cast-iron, one-piece housings, the units have a carbon-steel shaft protected with shaft sleeves, and heat-treated and ground high-strength steel gears. An interior channel guides oil to directly and constantly lubricate heavy-duty bearings on the output shaft. Double-lipped embedded oil seals prevent leakage. Mountable in most directions, the universally interchangeable compact design reportedly ensures easy OEM replacement.
