Trapezoidal screw drives

NEFF trapezoidal screws are manufactured from special semi-finished goods with high demands on straightness. The series conforms to DIN 103 and offers an extensive range of nuts made from various materials – all ready for installation. The very low backlash in the nuts allows radial forces to be absorbed.
