Low feed accuracy and fluctuations? High-Precision Ball Screws ensure precise axis motion

Preload eliminates backlash and increases rigidity and precision. It’s essential for positioning tasks but less relevant for transport purposes.

Rolled: cold-formed, cost-effective, medium precision.

Ground: precision-ground, offering the highest accuracy.

Whirled: formed by chip removal, faster than the ground version and more precise than the rolled variant.

Heavy-load types feature robust raceways and large balls. High-speed types use larger leads and special deflectors.

Shaft diameters from 4–300 mm, leads from 1–80 mm, lengths up to 12,000 mm (single-piece), and up to 22,000 mm (multi-piece assemblies).

Screws are made of induction-hardened special steel. Nuts are made from vacuum-carburized steel. This ensures durability and load capacity.

Service life can be calculated theoretically based on the bearing life formula. It depends on speed, load rating, and axial force.

DN = diameter × rotational speed. This formula helps calculate the maximum speed of the nut.

Various deflection systems (internal, external), flange shapes, multiple nuts, compact versions, and special threads.

Positioning types are preloaded (low backlash), transport types have backlash and are simpler—but not suitable for precise movement. High precision is also reflected in the purchase price.

Yes, there are single, double, and custom nuts. Replacement is usually straightforward with standard parts, and conditionally possible with special designs.

Typically via lubrication holes for oil or grease. Regular lubrication is crucial for service life and smooth operation.

Lateral forces must be strictly avoided. There should be no overconstraint from the screw bearings. Always mount or dismount the nut using a sleeve—otherwise, the balls may fall out.

Yes. There are miniature ball screws and compact designs with small outer diameters and shortened nuts—ideal for tight installation spaces.
