Baldor Electric Company STF-300-30-B-A Gear Reducer

Baldor Electric Company's STF-300-30-B-A Gear Reducer is a compact right-angle drive from Baldor's STF family designed to bolt into Baldor's 140TC mounting footprint. It delivers a 30:1 gear reduction with an output of 58 RPM, making it ideal for low-speed, high-torque needs in space-constrained equipment. This model is commonly used in conveyors, packaging lines, and automated machinery where reliable torque multiplication and smooth, controlled speed are required. Key verified specifications for STF-300-30-B-A include the 30:1 reduction ratio and 58 RPM output, with the 140TC frame indicating its mounting interface and overall size class. The unit is intended to be paired with compatible Baldor motors and accessories to form a robust drive train suitable for industrial applications that demand compact right-angle gear reduction. As with any gear reducer, performance depends on input speed, load, lubrication, and proper installation, so the STF-300-30-B-A offers a predictable balance of torque and speed in demanding manufacturing environments.
