Wittenstein SP140S-MC1-5-1K1-2K – SP+ 140 HIGH SPEED Planetary Gearbox, Ratio 5:1
The Wittenstein SP140S-MC1-5-1K1-2K is a single-stage, low-backlash planetary gearbox from the WITTENSTEIN alpha SP+ range, size 140. It is the SP+ HIGH SPEED (MC) version, designed for continuous operation.
- Ratio: 5:1
- Motor connection: clamping hub with a 38 mm bore
- Output: keyed output shaft
- Torque: up to 480 Nm maximum acceleration torque
SP+ gearboxes use helical toothing and tapered roller output bearings, and are lubricated for life. This makes them a standard choice for precision servo axes in machine tools, automation and handling systems.
