Baldor Electric Company F-921-25-B5-G Gearbox

BALDOR ELECTRIC COMPANY F-921-25-B5-G Gearbox is a 25:1 right-angle gear reducer designed to pair with Baldor's 56C motor mounts via a B5 output flange. It accepts about 0.89 horsepower of input at 1,750 RPM and provides a 25:1 reduction, giving an output speed near 70 RPM. The gearhead is specified to deliver up to roughly 675 in‑lbs of output torque, making it suitable for compact drives that require higher torque at reduced speeds. In Baldor catalogs this model is listed as F-921-25-B5-G and is sometimes shown under LF-921-25-B5-G in related documentation, reflecting naming variations across Baldor’s literature. The unit is part of Baldor’s 900-series right‑angle gear reducers and uses a solid‑shaft input with a 56C mounting pattern configured for standard Baldor motor couplings, along with a B5 output flange for straightforward attachment of driven components. With its compact footprint and fixed gear ratio, the F‑921‑25‑B5‑G provides predictable, low‑speed performance for light‑ to mid‑duty applications where reliable torque at a reduced speed is essential.
