  • Trapezoidal-threaded spindles
  • Diameters up to 120mm
  • 6 types of nuts available
NEFF trapezoidal lead screw TGT

NEFF trapezoidal spindles are produced according to DIN 103. Rolled spindles have exceptionally good running properties.

The trapezoidal sliding nuts are made of a copper-bronze alloy as standard (material 2.1090, G-CuSn7ZnPb, RG7).
Available in cylindrical shape or with flange. In addition, trapezoidal nuts in layered bronze with a higher strength, in plastic version or as steel nuts are available.
