Version B: Inside the gear unit a groove secures the spindle over its entire length against twisting. Thus the load can simply be applied.

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. Protective sleeve: The versions A and B are, unless stated otherwise in the order, supplied with a protective sleeve. Version B: Is the same as version A, but inside the gear unit a groove secures the spindle over its entire length against twisting. Thus the load can simply be applied. Versions A and B are avaliable with an optional spindle end safety feature. This means the threaded spindle is locked before the safety sleeve is mounted, to limit the stroke in extended position so that the spindle cannot be screwed out of the gear unit. Attention: this safety feature means the safety sleeve is by about 20 mm longer. The product numbers below only refer to the basic gear units without spindle. 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. On request a version for lower stroke speed can be supplied.
