Spur gearbox

Building worm gearboxes compact

ROTEK motors with worm gears are used wherever a force deflection of 90° or a second shaft end is required for space reasons. The bronze worm gears guarantee a long service life under high loads.

The gearboxes are also available with worm gears made of hard fabric for use in noise-critical areas such as medical or laboratory technology. They are optionally available with a hollow shaft.
