Wittenstein LP120S-MF1-5-1I1-3S – LP+ 120 Single-Stage Planetary Gearbox, Ratio 5:1
The Wittenstein LP120S-MF1-5-1I1-3S is a single-stage planetary gearbox from the WITTENSTEIN alpha LP+ range (alpha Basic Line), size 120. It has:
- a 5:1 ratio
- a maximum acceleration torque of 220 Nm
- 97% efficiency
- a 32 mm clamping hub for direct servo motor mounting
- lifetime lubrication
The LP+ is WITTENSTEIN’s economical servo gearbox. Size 120 brings it to higher torques for heavier positioning and auxiliary axes where cost matters more than very low backlash.
