Industrial SP140S-MF1-7-1I1-2S Planetary Gearbox Reducer

The SP140S-MF1-7-1I1-2S planetary gearbox reducer from ALPHA (WITTENSTEIN Alpha) is a compact, low-backlash gearing solution designed for servo-driven systems, delivering a 7:1 reduction in a flange-mounted housing. It weighs about 20 lb (approximately 9.1 kg) and features a straight shaft entrance for the input side and a keyed output shaft at the flange-mounted exit. This model is described as low-backlash and is part of the SP+ planetary gearbox family optimized for rotary servo motors, enabling precise speed and torque control in compact packages. The flange-mount configuration and a standard keyway exit facilitate straightforward mounting to compatible servo motors and downstream gear trains in automation systems. Typical applications include robotics actuators, packaging and material-handling equipment, automated conveyors, and CNC axes where reliable torque multiplication, repeatable positioning, and a compact footprint are essential.
