  • Ball screw with sliding nut
  • Diameters up to 80mm
  • Nuts type GGS and GGM
NEFF ball screw with sliding ball nut GGT

Instead of a ballscrew nut, the ballscrew is fitted with a sliding nut.
This nut has the negative profile of the ballscrew. A combination of high pitches and thus the high dynamics of the ballscrews with the lower cost of the nuts.

The choice of a high-quality plastic version ensures that the spindle / nut runs without lubrication. An important feature that offers advantages in many industries. For example the food industry, cleanroom technology.

The standard program consists of rolled ballscrews. In addition, polished or swirled versions are available.

The NEFF ball screw type KGT has a maximum axial play of 0.05 mm. Optionally with reduced clearance or with preloaded ballscrew.
The NEFF range of ballscrews complies with DIN 69051.

High mechanical efficiency of 98%.

Tolerance classes

The standard pitch deviation for rolled ballscrews falls in the tolerance class T7 (52μm/300mm).
Optionally, spindles can be produced with an accuracy that falls within the tolerance class T3 (12μm / 300mm).
