W2502SA-4P-C5Z5 NSK Ball Screw Large Steel Ball Preload Ball Screw

The W2502SA-4P-C5Z5 is an NSK SA type finished ball screw, meaning that both ends of the screw shaft have been precision-machined according to NSK standard support units at the factory and can be directly installed and used. The NSK ball screw W2502SA-4P-C5Z5 has a shaft diameter of 25 mm, a lead of 5 mm, an accuracy class of C5, and uses a tubular circulation structure, making it suitable for positioning and reciprocating motions in machine tools.

NSK SA series pre-machined ball screws are high-precision ball screws for machine tools. Their features include:

The shaft end is pre-machined to standard specifications, allowing direct installation of bearings and couplings.

Suitable for CNC machine tools, automated equipment, and high-precision positioning mechanisms.

Common accuracy grade is C5.
Features a high-rigidity design, suitable for high-speed feed and heavy loads.

Compared to the unmachined SS series, it reduces secondary machining time for customers.

Applications of SA type W2502SA-4P-C5Z5 ball screws:

CNC machine tools: such as machining centers, milling machines, EDM machines, etc.

Precision measuring equipment: such as coordinate measuring machines, image measuring instruments.

Automation and robotics: robots or automated assembly lines requiring high positioning accuracy.

Semiconductor manufacturing equipment: such as lithography machines, wafer inspection equipment.

Other precision machinery: medical equipment, precision printing presses, etc.
