The efficiency η depends on the helix angle and reaches values from ~0.5 to 0.75
In general, Eichenberger screws are produced as bars with a
length of 3 m. Depending on the diameter and the material availability, lengths up to 6 m are also possible on request.
Any kind of end machining
By default leadscrews are cut to the desired length without Special machining.
Upon request, a so-called standard screw end journal with
three turned bearing seats is available. Dimensions are as per
Our speciality is any application-specific end machining: Tell us
your requirements, and we’ll provide YOUR tailor-made screw!
In each instance, a detailed drawing would be necessary.
Speedy, Easy and Rondo leadscrews are precision parts and
must be protected from shock, dirt or moisture when transported
or stored. Please do not unpack until ready for use.
Please check for cleanness when mounting a leadscrew. Dirt or foreign matter on the thread may cause increased wear and premature failure.
Please consult lubrication recommendation before mounting or
Radial loads and torque
Radial loads or torque brought to bear upon the nut result in overload of individual contact surfaces, thus seriously affecting the service life of the leadscrew assembly. Therefore it is important to properly mount the screw and to comply with all relevant form and positional tolerances.
In some cases, a single lubrication with grease or oil is sufficient. However, any lubrication cycle depends on the application environment.
Bronze nuts have to be lubricated regularly.
Recommended all-purpose lubricant:

Eichenberger Speedy, Easy and Rondo leadscrews are suitable for numerous applications: On the one hand, for shorter lifts, they are a great substitute for belt drive systems because of their lower engineering effort. On the other hand, they are also an excellent substitute for hydraulic and pneumatic lift cylinders because they can be freely accelerated and positioned, and work independently of secondary energy sources. Thanks to high Efficiency and excellent value for money, they are an ideal alternative to trapezoidal screws or ballscrews in particular areas of use.
