The NEFF Sliding Drives are based on NEFF ball screws. The sliding drive is completed with a sliding nut, manufactured with the negative profile of the ball screw, instead of (using) a ball screw nut.
The generated sliding drive combines high pitches and dynamic of the ball screw with the lower costs of the trapezoidal threaded spindles.
Choosing high-quality plastics allows the lubricant-free running of the sliding drive – a significant characteristic with advantages in many businesses (e.g. food industry, clean room technology etc.), which excludes many problems in advance.
The interaction of sliding ball nuts (GGM) made from plastics with integrated ball screw negative profiles makes NEFF ball screws to a sliding drive.
