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.
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.
