Boston Gear RF726-20-B7-J Gear Reducer

Boston Gear RF726-20-B7-J Gear Reducer is a 700 Series, 20:1 ratio single‑reduction worm gear drive designed for compact right‑angle installations. It features a 140TC input flange and a 2.6" center distance, with an output shaft diameter of 1.125" and a solid projecting output profile. At 60 Hz operation, the unit provides an output speed of roughly 87.5–88 rpm and supports up to about 2 hp input, making it suitable for moderate‑power drives where space is limited. Torque ratings cited for this family vary by configuration, commonly reported around 1,180 in‑lb to 1,483 in‑lb, reflecting catalog variations in gear geometry and lubrication. The RF726‑20‑B7‑J uses worm gear technology to deliver high torque at low speeds with low backdrive, and it aligns with standard Boston Gear mounting patterns used in 140TC assemblies for straightforward integration with compatible motors and driven components. Built for industrial reliability, this reducer offers durable performance in automation, conveyors, and packaging equipment where a compact, right‑angle drive is advantageous.
