Version C: The spindle is fixed to the worm gear. The axial movement is taken over by the threaded nut running outside the gear unit.

Housing: Made from aluminium alloy in die-cast version. All sides machined. As standard filled with lubricant.

Gearing: Worm made from ETG100, Gear made from Gbz12. Self-locking to a certain extend. Vibration, an increase in the spindle pitch or the use of rolling screw elements release the self-locking. In this case, e.g., a brake motor should be included in the system. For lower stroke speeds, worm gear sets with higher transmission ratios can be supplied on request.

Spindle: Material C15, from size 4 C45. On request also available as left-hand, stainless steel or ball screw version. Version C: In this version the spindle is fixed to the worm gear. The axial movement is taken over by the threaded nut running outside the gear unit (also 1 mm stroke per full rotation of the worm shaft).
