Ball Screws for Ultra High Vacuum Applications
Any Steinmeyer ball screw, from 3.0 to 160 mm in diameter, can be completely customized to meet a company’s vacuum requirements. All components utilized in such a ball screw, including shaft, ball nut body, ball deflectors, and balls, are manufactured from stainless steel. Depending on the application, the ball screw is provided with either vacuum compatible grease or a dry lubricant coating such as tungsten disulfide or molybdenum disulfide. For certain special demands, the ball nut can be supplied with silicon nitride balls.
