High-performance series
HP series Ball Screw Assemblies are available with
nominal diameters of 20 - 63 mm, and leads of 10 - 40 mm.
The HP nut type is a single nut with flange which is available with
a driven screw or as a driven nut.

Driven single nut with flange FAR-B-S
Fundamental advantages of systems with driven nuts
Moment of inertia
In the case of long screws, the screw does not have to be rotated in the acceleration phase, only the nut.
The mass moment of inertia of the screw is not therefore critical. The moment of inertia of the nut is comparatively low and it is no longer
dependent on the required stroke.
Dynamics
The intricate end bearing designs required for high dynamics, for example, fixed bearing on both ends with angular-contact ball bearings,
are no longer necessary.
Screw extenders
Since the screw is stationary, relatively effort is needed to stretch the screw
--
Increase in permissible axial loading (buckling load); not limited by end bearings
-–
Compensation of temperature influences
-–
Increase in overall rigidity
Design and manufacturing tolerances
The use of nuts with a high level of axial and radial runout precision minimizes the induced screw vibration. All functional components are
supplied from a single source. In-house designs are no longer needed.
Liquid cooling
Improved cooling can easily be provided by using a hollow-bored screw:
cooling of the stationary screw can be provided with comparatively little effort. Controlled cooling virtually eliminates changes in length
due to temperature fluctuations.
User benefits

Adjustment to various speeds and loads is possible using the
screw lead and the speed reducing belt
--
Small installation space thanks to its compact construction

-–
Integral functionality and little installation work for the customer
-–
Low system costs
-–
High positioning accuracy
