NEFF ball screw drives are the result of many decades of innovative ongoing development of the ball screw drive. We offer precision-rolled ball screw drives in all common sizes at competitive prices and in extraordinary quality. NEFF ball screws correspond to DIN 69051 and the NEFF standard (exchangeability of EFM trapezoidal nuts with ball nuts). The screws are available with customised end machining or with soft-annealed ends for further machining if requested. The high mechanical efficiency < 98 % requires a lower driving power and a significantly lower breakaway torque than with trapezoidal screw drives. Thanks to the low rolling friction and deflection systems that have been developed further over many years, Neff ball screw drives have a particularly long and reliable service life.
