A line of long lead ball screws features a ball circulation system designed to promote high linear speeds and low noise levels. These ball screws are suitable for providing precise positioning in a wide range of linear-actuation applications, including packaging and automation systems, laser cutting, woodworking, and production machinery. The 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. Long lead ball screw diameters range from 25 to 50 mm and leads range from 20 to 50mm. The 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 and flanged nuts configurations. Standardized long lead screws users can be customized to satisfy any particular application specifications.
