Product highlights

High performance

The NVH worm gearbox convinces with a high performance in economical standard applications in cyclic and continuous operation.

No stick-slip effect

The stick-slip effect is not an issue in applications with the NVH thanks to the perfected hollow-flank toothing.

High flexibility

In addition to the hollow shaft, the worm gearboxes are also available in a corrosion-resistant design.

Radial shaft seal

  • Very long service life
  • Optimized for continuous operation

Hollow-flank toothing

  • Medium torsional backlash accuracy over the entire service life
  • High efficiency
  • High power density

Input bearing

  • Bearing package to absorb axial and radial forces
  • Very well suited to high input speeds

Output bearing

High overload capacity to absorb axial and radial forces

Metal bellows coupling

  • Completely backlash free
  • Lifetime durable and maintenance free
  • Easy assembly
  • Protects the motor through thermal linear expansion compensation
