Ball screws for demanding applications 17 November 2021

The new Schneeberger ball screws (SBS) are suitable for use at high and low speeds as well as oscillating short stroke movements. This makes them particularly attractive for demanding applications in machine tools as well as measuring and testing technology.

Schneeberger is expanding its extensive linear technology portfolio with the new SBS ball screws. In order to ensure these characteristics over the long term, the ball bearing raceways, bearing seats and contact surfaces of the ball screws are precision ground. The spindle outer diameter that is ground with the bearing seats in the same clamping process combines a two-fold benefit. Sven Vitt, the SBS project manager at Schneeberger, explains: "On the one hand, the ball screw can be aligned to the spindle outer diameter, and on the other hand, the efficiency of the wiper systems is significantly increased." Vitt ascribes equal importance to the induction-hardened spindle and the through-hardened nut.

Overall, the precise and hard ball contact surfaces enable optimum force transmission with extremely high positioning and repeat accuracy. In addition, Schneeberger ball screws stand out due to their quiet, torque constant running behaviour. Equally important are the accompanying low heat generation, minimal wear and long service life.

All these characteristics set new standards for use in demanding sectors, including the machine tool industry, measurement and testing technology, drive and process technology as well as robotics and automation. Depending on requirements, the SBS is available with spindle diameters of 32mm, 40mm, 50mm and 63mm. The manufacturer specifies a maximum thread length of 2,000mm for all sizes. The implementable increases in speed are 1.5g and the maximum speeds 96m/min. The accuracy class according to ISO – type P is IT3. Schneeberger application technicians and engineers are always ready to assist with the evaluation and design of customer projects.
