Boston Gear F732-40-B7-G Inline Worm Gear Reducer

Boston Gear F732-40-B7-G is an inline worm gear reducer that provides a 40:1 reduction in a compact, cast-iron housing designed for reliable torque multiplication in industrial drive trains. The unit accepts a 140TC input flange and consolidates a center distance of 3.2 inches, with a left-side solid output shaft measuring 1.375 inches in diameter for straightforward coupling to downstream components. This variant is documented with G assembly and no base, supporting mounting configurations that don’t require a base plate. This single-reduction reducer is built for continuous operation under typical factory loads, delivering steady torque transfer and the smooth behavior characteristic of worm gear designs. It is commonly used in conveyors, packaging lines, feeders, and other light- to mid-duty automation applications where precise slow-speed output and robust reliability are essential. The rugged cast-iron housing aids in heat dissipation and durability in harsh industrial environments.
