Version C: In this version the spindle is fixed to the worm gear. The axial movement is taken over by the ball screw 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. Due to the high efficiency (low friction between spindle and nut), ball screws are not self-locking. To prevent runback, a brake motor should be fitted, for example.
Spindle: Ball screw material Cf53 rolled, induction hardened 60 ±2 HRC and polished.
The product numbers only refer to the basic gear units without spindle and accessories. Please ask for the price of the complete unit including spindle and accessories as, e.g., flange plate/travelling nut, bellow or coil spring cover, fastening strips.
