The OTT worm gear is a patented high-precision worm gear set where the backlash can be set and adjusted. All OTT worm gears are manufactured to the highest quality.

The worm gear is comprised of a pinion gear shaft and ring gear. The backlash is adjusted by turning or moving the pinion gear relative to the ring gear.

Due to the height of the tooth there is a significantly larger contact ratio than with a normal worm gear. This results in greater power transmission with great component accuracy.

The OTT-MATIC is another refinement of the OTT worm gear. The backlash can be adjusted by moving the ring gear axially relative to the pinion gear during rotation.
