W2805SA-1P-C5Z5 high rigidity ball screw NSK SA series ball screw

The NSK SA type ball screw W2805SA-1P-C5Z5 has a screw shaft outer diameter of 28mm, a lead of 5mm, and an accuracy class of C5.

The W2805SA-1P-C5Z5 SA type ball screw comes standard with a flanged single nut PFT and uses interference ball preload to achieve zero backlash. Its rated dynamic load is 13000N and rated static load is 24400N.

The main features of the NSK W2805SA-1P-C5Z5 ball screw are as follows:

Core Positioning: The NSK SA series precision-grade shaft-end finished ball screw is designed specifically for small and medium-sized CNC machine tools and precision automation equipment.

High Precision and Zero Backlash: The W2805SA-1P-C5Z5 ball screw has a precision grade of C5. The "P" in the model number indicates an interference-loaded ball preload method, achieving zero axial backlash, effectively eliminating reverse stroke and ensuring accurate and stable positioning.

Long Life and Easy Installation: The screw shaft undergoes precision heat treatment, achieving a surface hardness of HRC 60-65, making it wear-resistant, durable, and with excellent precision retention. The W2805SA-1P-C5Z5 shaft-end finished ball screw features a standardized design, with the shaft end machined pre-machined at the factory, allowing direct compatibility with NSK standard support units, significantly shortening the assembly cycle.

NSK SA-type precision ball screws, characterized by high rigidity, high precision (C5 grade), and pre-machined shaft ends, are primarily used in industrial equipment requiring extremely high load-bearing capacity and positioning accuracy.

Core Application Areas: CNC Machine Tools, Automated Precision Machinery, Semiconductor and Electronic Manufacturing Equipment, Medical and Optical Instruments, Precision Measurement and Testing Equipment, Injection Molding and Stamping Equipment
