Trapezoidal Screw Drives (TGT)

Trapezoidal-threaded spindles combined with trapezoidal ball nuts to a trapezoidal screw drive.The rolled NEFF-Trapezoidal Threads conform to DIN 103. By rolling the trapezoidal threads we realize a very high firmness and surface quality which lead, together with the trapezoidal ball nuts, to extraordinary good operating characteristics. Additionally, the trapezoidal threads are produced in a higher range of tolerance: you get norm compliant trapezoidal threads with very low backlash.

The trapezoidal travelling nut, produced from red brass by standard, (raw material 2.1090, G-CuSn7ZnPb, RG7), are available either cylindrical or with flange.
We also deliver trapezoidal ball nuts in bearing bronzes with higher solidity, as plastic nuts or as steel nuts.

Trapezoidal-threaded spindles (RATS, RPTS)

The rolled NEFF trapezoidal threads are characterized by a high constant precision, due to production in a restricted tolerance zone.

Material standard is 1.0401/C15.
We also offer an extensive program of trapezoidal threads from rustproof material (1.4305/X8CrNiS18-9), RATS.
