Wittenstein SP140S-MF1-10-0I1-2S – SP+ 140 Planetary Gearbox, Ratio 10:1, Reduced Backlash
The Wittenstein SP140S-MF1-10-0I1-2S is a single-stage precision planetary gearbox from the WITTENSTEIN alpha SP+ range, size 140. It is the MF version for cyclic operation, with:
- a 10:1 ratio
- reduced backlash (≤ 1 arcmin)
- a 32 mm clamping hub for direct servo motor mounting
- a maximum output torque of up to 720 Nm
SP+ gearboxes use helical toothing and tapered roller output bearings, and they are lubricated for life. This makes the SP+ 140 a robust, high-precision choice for heavy servo axes in machine tools and automation.
