In addition to the OTT worm gears we also manufacture other worm gear types as listed.
Standard worm gears
According to DIN or customer specifications.
Duplex worm gears
The Duplex worm gear has two different pitches. The backlash can be adjusted by moving the worm gear axially.
Special design worm gears
With custom designs the tooth height is increased, the pressure angle reduced and the partition of the tooth width between worm and ring gear modified.
