Boston Gear HF715B5KB5HP16 Speed Reducer Gearbox

Boston Gear HF715B5KB5HP16 Speed Reducer Gearbox is a right-angle, single-reduction worm-gear drive from the 700 Series with a hollow-shaft output and quill-flange input for compact, configurable mounting. It provides a 5:1 reduction, with an input speed of 1,750 rpm and an output speed of 350 rpm, delivering a rated output torque of 291 in-lb, and an input power rating of 1.72 hp. The design uses a high-strength bronze worm gear set paired with heavy-duty bearings to handle thrust and overhung loads, while the output shaft is a robust steel member suitable for direct connection to belts, pulleys, or other driven components through a hollow bore. Applications include packaging machinery, conveyors, mixers, and other automation tasks where space is at a premium and a hollow-output drive simplifies coupling. This HF715B5KB5HP16 configuration features quill-input compatibility and hollow-shaft output, making it a versatile choice when a compact, durable gear reducer is needed to achieve reliable speed reduction and torque delivery in tight installations.
