Miniature ball screw drives are primarily used in the semiconductor industry, as well as in optical, medical and measurement engineering applications. Our portfolio of miniature ball screw drives offers a total of 5 different nut shapes for your mounting design. The nuts can be provided either with preloading (for zero backlash) or axial play. They can be combined with two standard types of shafts or a custom shaft. Ground recirculating ball screws are available in accuracy classes P1 to P5. Rolled versions with lower accuracy exist starting from a minimum nominal diameter of 8 mm. Special versions, for example for clean room applications or vacuum engineering, are available upon request. Our experience and proven quality is evident here too.
