Boston Gear F71520B5G Right Angle Speed Reducer

Boston Gear F71520B5G is a 700 Series single‑reduction right‑angle worm gear speed reducer with a 20:1 reduction ratio that delivers power through a 90‑degree drive path. The F715‑20‑B5‑G designation identifies a right‑angle configuration and a mounting style that aligns with a standard C‑face, 56C motor flange for straightforward installation. This model provides a nominal output of 88 RPM, consistent with a 20:1 ratio when paired with typical motor speeds, making it suitable for compact drive setups where space is at a premium. As part of Boston Gear’s established 700 Series, the gearbox uses a worm gear reduction in a compact housing, intended for durable operation in industrial equipment and automation tasks that require reliable, low‑speed, high‑torque transfer in a right‑angle configuration. Manufactured under the Boston Gear brand, a unit of Altra Industrial Motion, the F71520B5G embodies the series’ emphasis on a robust, space‑efficient gearbox solution for 56C motor interfaces and 90‑degree drive requirements.
