Worm Gear Screw Jacks NPT, with Trapezoidal Thread, Version C: Travelling nut version

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).

You will find further dimensions on our catalogue page.

1) Stroke pro full rotation of the input shaft.

2) Required torque at max. load (only under optimum conditions, with run-in spindle)
