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.
