Product highlights

Consistently high performance

Constant backlash throughout the service life of the gearbox ensures a consistently high performance.

Low maintenance

Highest quality standards guarantee a long service life and extend maintenance intervals.


High speeds increase machine output.


The right-angle design allows for shorter machine concepts due to being short in the axial plane.


Extremely reliable gearboxes prevent cost-intensive machine breakdowns. 

Taper roller bearings for absorbing axial and radial forces

Output compatible with SP+ series

Variable output connection, also rearward

High-quality hypoid gearing for a higher torque and smoother operation

Metal bellows coupling at the input: Length compensation to protect the motor bearing

WITTENSTEIN alpha in all axes
