Worm gear screw jack NPT size 4 version A basic gearbox without spindle for spindle Tr.40×7 (For operating instructions please visit the download area of our website www.maedler.de) PN: 47500400

Version A: Standard version. The threaded spindle moves 1 mm
inaxial direction with every full rotation of the worm shaft. The object
to be moved must be secured against twisting.

Housing: Made from aluminiumalloy in die-cast version. All sides
machined. As standard filled withlubricant.

Gearing: Worm made from ETG100, Gear made from Gbz12.Self-locking
to a certain extend. Vibration, an increase in the spindlepitch or the
use of rolling screw elements release the self-locking. Inthis case,
e.g., a brake motor should be included in the system. Forlower stroke
speeds, worm gear sets with higher transmission ratios canbe supplied on
request.

Spindle: Material C15, from size 4 C45.On request also available
as left-hand, stainless steel or ball screwversion.

Protective sleeve: The versions A and B are, unlessstated
otherwise in the order, supplied with a protective sleeve.

VersionA: With this standard version the threaded spindle moves 1
mm inaxial direction with every full rotation of the worm shaft. The
spindlehas to be secured against twisting. Versions A and B are
avaliable withan optional spindle end safety feature. This means the
threaded spindleis locked before the safety sleeve is mounted, to limit
the stroke inextended position so that the spindle cannot be screwed out
of the gearunit. Attention: this safety feature means the safety sleeve
is by about20 mm longer.

The product numbers below only refer to the basic gearunits without
spindle.
Please ask for the price of the complete unitincluding
spindle and accessories as, e.g., flange plate/travelling nut,bellow or
coil spring cover, fastening strips. On request a version forlower
