W2805SA-2Z-C5Z5 NSK Precision Ball Screw SA Type ZFT Ball Screw Nut

The NSK W2805SA-2Z-C5Z5 is an NSK SA series shaft-end finished ball screw with a diameter of 28mm and a lead of 5mm. It adopts a single-nut offset preload and C5-grade precision design, which has high transmission accuracy, rigidity and smooth operation.

Features of W2805SA-2Z-C5Z5 Offset Preload Ball Screw:

High-Precision Transmission: The W2805SA-2Z-C5Z5 ball screw adopts a C5 precision grade, achieving high repeatability and positioning accuracy, suitable for precision machining equipment.

High-Efficiency Design: Low ball circulation friction results in significantly higher transmission efficiency than traditional sliding screws, reducing drive energy consumption.

High-Rigidity Structure: The SA type structure has excellent axial rigidity, capable of withstanding high loads and improving equipment machining stability.

Low-Noise Operation: Optimized ball circulation method ensures smoother and quieter operation.

Standardized Installation: A-Series standardized shaft end design facilitates installation with support units and servo systems.

NSK SA type pre-finished ball screws are widely used in CNC machine tools, semiconductor equipment, industrial automation, new energy equipment, medical instruments, and aerospace industries. Because their shaft ends are pre-machined to a standardized finish, they can be directly installed and used, effectively shortening equipment assembly cycles, reducing processing costs, and improving overall assembly consistency.
