Description
Version A: In this standard version, the ball screw spindle moves in the axial direction. The object to be moved must be secured against rotation. 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. Protective sleeve: The versions A and B are, unlessstated otherwise in the order, supplied with a protective sleeve. 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. You will find further dimensions on our catalogue page. 1) Efficiency. Values in brackets for version with higher transmission ratio (slow-running version). 2) Stroke pro full rotation of the input shaft. 3) Required torque at max. load (only under optimum conditions).
