Boston Gear F713-20-B5-H Speed Reducer

The Boston Gear F713-20-B5-H is a 700 Series single‑reduction, right‑angle worm gear drive designed for compact, space‑constrained installations. It features a quill flange input and a solid projecting output shaft, making it suitable for shaft‑to‑shaft coupling in tight layouts. This 20:1 reducer delivers about 0.52 hp input and 0.43 hp output (with a 0.5 hp motor horsepower rating) and provides an output speed of 87.5 rpm with a torque rating of 308 in‑lb, reflecting its capability to multiply torque while lowering speed in demanding applications. The unit’s right‑angle configuration and 20:1 ratio typify Boston Gear’s rugged 700 Series, which is commonly employed to couple motors to driven loads in conveyors, packaging, and machine tools where a compact gearhead is advantageous.
