Ball Screws deliver high linear speeds with minimal noise.

Press Release Summary:

Promoting precise positioning in linear-actuation applications, long lead ball screws feature ball circulation system that maximizes linear speeds and minimizes noise. Products have nut with axial play (Series SL) or backlash elimination (Series BL). Also available, rotating nut design (Series SLT and BLT) allows drive motor to move with nut, resulting in linear speeds to 110 m/min. Long lead ball screw diameters range from 25-50 mm, and leads range from 20-50 mm.

SKF® Long Lead Ball Screws Deliver High Linear Speeds with Less Noise


SKF® long lead ball screws feature a unique ball circulation system designed to promote high linear speeds and low noise levels. These ball screws are ideally suited to provide precise positioning in a wide range of linear-actuation applications, including packaging and automation systems, laser cutting, woodworking, and production machinery, among others.

Long Lead ball screws are available with a nut with axial play (Series SL) or with backlash elimination (Series BL) to achieve the desired operation. Smooth performance is enhanced with the optimized end cap ball recirculation system.

The standard product range also includes a rotating nut design (Series SLT and BLT) for applications where critical speed or inertia is an issue. The SLT and BLT rotating nut option is a design that allows the drive motor to move with the nut, which results in reduced inertia, less required power, and even higher linear speeds up to 110m/min.

Long lead ball screw diameters range from 25mm to 50mm and leads range from 20mm to 50mm.

All SKF long lead ball screw assemblies can be equipped with the necessary end machining and with the support bearing package pre-assembled and ready to go. They can further be customized with double protection wipers and brush wipers in both cylindrical or flanged nuts configurations. Standardized long lead screws users can be customized to satisfy any particular application specifications.
