Space-saving right-angle precision with output shaft

The representatives of our versatile hypoid gearboxes with SP⁺ compatible output geometry. SK⁺ gearboxes are appreciated for their high precision and efficiency as well as the possibility to combine different options for the gearbox output. With an optional planetary pre-stage it is possible to reach highest input speeds.

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.

Speed

High speeds increase machine output.

Compactness

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

Reliability

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
