New SKF® Long Lead Ball Screws(Pic)

New SKF® long lead ball screws with a rotating nut design provide precise positioning and offer compact, ready-to-use, and easily incorporated solutions for linear-actuation applications requiring high speeds and long strokes. Their design allows the drive motor to move with the nut to reduce inertia, require less power, and achieve even higher linear speeds up to 110m/min.



Applications include packaging and automation systems, laser cutting, and production machinery, among others.

Unlike traditional ball screws with rotating screw shafts, these integrate a nut rotating inside the bearings and along the fixed long-lead screw shaft. The motor moving with the nut minimizes the inertia and critical speed problems typically associated with long rotating screw shafts and promotes optimized performance.

Design features include angular contact bearings directly mounted on the nut and preloaded in an
