Boston Gear F710-15-B4-J Speed Reducer Gearbox

The Boston Gear F710-15-B4-J is a 700 Series worm gear speed reducer designed for compact, right-angle drive applications. It provides a 15:1 reduction in a rugged cast‑iron housing and is configured for single‑stage reduction. Input configurations documented for this model include a 42CZ flange input or a quill‑flange input, depending on the catalog listing, with a 1" center distance. The output is a right‑side, solid projecting shaft with a 0.5" diameter bore, enabling direct coupling to small driven equipment. Rated for up to 0.33 hp at the input, the unit delivers about 0.27 hp at the shaft, producing an output speed of roughly 116.7 rpm and peak torque around 146 in‑lb. This combination makes the F710-15-B4-J suitable for light‑ to medium‑duty drives in small conveyors, feeders, packaging lines, or automation subassemblies where quiet, reliable worm‑drive reduction and straightforward mounting are advantageous.
