Boston Gear F724B-40S-B5-G Speed Reducer Gearbox

Boston Gear F724B-40S-B5-G Speed Reducer Gearbox is a 700 Series single-reduction worm-gear drive that delivers a precise 40:1 reduction in a compact, right-angle package designed for direct coupling to standard motors via a C-face, 56C flange interface, with a focus on reliability and interchangeability within the 700 Series lineup. The G assembly uses a B5 foot-mount configuration and provides a 2.4-inch center distance, with a left-side, solid projecting output shaft measuring 1.125 inches in diameter, and a C-face input designed to mate with 56C flange motors. The unit accepts up to 1 hp input and offers a maximum output torque of 1,206 in-lb, driving the output at roughly 44 rpm when fed by a standard 1,760 rpm motor, making it suitable for low-speed, high-torque applications in compact machinery. With its robust construction and standard interfaces, this gearbox supports reliable operation in space-constrained environments where a worm-drive reduction stage is required to maintain torque while reducing speed.
