SHAC DFU 4005-4 Double Ball Nut, 40 mm, 5 mm Lead, High-Rigidity CNC Nut
The SHAC DFU 4005-4 double ball nut is a 40 mm, 5 mm lead nut for heavy CNC axes that need high stiffness with fine feed resolution. Its preloaded twin-nut construction gives excellent backlash control and rigidity, ideal for precision positioning under large cutting loads. SHAC is produced in China but engineered to compete directly with Taiwanese linear motion brands, offering noticeably higher running quality than typical Chinese options like WERB. Abdul Traders holds the exclusive distribution rights for SHAC in Pakistan, so all genuine DFU 4005-4 nuts come through our channel.
Key Features
Premium SHAC double ball nut for 40 mm, 5 mm lead ball screws, designed for applications where rigidity and accuracy are more important than maximum speed. The DFU 4005-4 twin-nut design is factory preloaded to reduce backlash and improve surface finish. Compared with standard Chinese brands, SHAC offers Taiwan-level smoothness and life, making the higher price a strong value for professional CNC users in Pakistan.
Technical Specifications
DFU 4005-4 SHAC is a precision-ground double ball nut matched to 40 mm diameter, 5 mm lead ball screws. It features a flanged body, internal ball return system, and preload adjustment to achieve tight axial play. When installed on a compatible 4005 screw, it delivers high positional accuracy and repeatability for heavy CNC equipment and automation lines.
Industrial Applications
Used on large CNC routers, boring machines, and heavy automation axes that require slow, powerful feeds with very stable positioning.
