Version B: As version A, but the ball screw is secured against
rotation by a square protective sleeve. The load only needs to be
applied.
Housing: Made from aluminium alloy in die-cast version. All sides
machined. As standard filled with lubricant. Protective tube steel,
blank.
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.
