Worm gear sets

Standard worm gear sets

The worm shafts are made from 16MnCrS5BG, hardened and grounded. Various worm shaft versions are available. Alongside a worm shaft with a cylindrical shaft end and feather key groove, there are versions with short, toothed shaft ends. The short shaft end has a toothed shaft profile according to DIN 5482 - including the ZAE type K coupling.
The worm gear unit rims are manufactured from centrifugally cast solid bronze GzCuSn12Ni with excellent anti-friction properties
