SFU 4005-4 WERB

WERB SFU 4005-4 Standard Ball Nut | For 40 mm CNC Ball Screw, 5 mm Lead

The WERB SFU 4005-4 standard ball nut is designed for 40 mm CNC ball screws with 5 mm lead, used on very heavy-duty CNC and automation axes that demand high rigidity and precise positioning. It provides smooth, controlled motion when paired with a correctly machined screw. As the authorised WERB ball screw supplier in Pakistan, keeps SFU 4005-4 ball nuts available for large industrial installations.

Key Features

Standard WERB flange ball nut for 40 mm ball screws with 5 mm lead, suitable for heavy-load axes that still require fine feed control. The SFU 4005-4 design uses recirculating balls in hardened raceways to minimise friction and maintain accuracy under load. Its large flange body offers a strong mounting interface on robust machine structures.

Technical Specifications

SFU 4005-4 WERB is matched to 40 mm diameter ball screws with 5 mm lead and the correct WERB groove profile. The nut body is produced from high-quality steel with hardened, precision-ground ball tracks for long service life in demanding environments. When combined with a compatible WERB ball screw, heavy-duty supports, and couplings, it forms a precise drive system for large CNC machines in Pakistan.

Industrial Applications

Used on large CNC gantries, heavy cutting machines, press feeds, and industrial automation axes that use 40 mm, 5 mm lead ball screws. Favoured by major OEMs and maintenance teams that rely on WERB China-quality ball screw components from .
