W2509FA-1P-C5Z20 Medium Lead Ball Screw External Circulation Ball Screw

The NSK W2509FA-1P-C5Z20 ball screw is a mid-lead precision ball screw with an outer diameter of 25mm and a lead of 20mm. It is 1113mm in length and features C5-grade precision and a preload design to achieve zero axial backlash. The W2509FA-1P-C5Z20 is a pre-machined flange-type ball screw with a compact structure and high load-bearing capacity, suitable for linear transmission applications in automated equipment and CNC machinery where speed and rigidity must be balanced.

Key features of the NSK W2509FA-1P-C5Z20 ball screw:

Pre-machined shaft end: The mounting section and threads are pre-machined at the factory, allowing for direct assembly and use, reducing processing costs and errors.

High precision and zero backlash: It features C5-grade precision and achieves zero axial backlash through preload, eliminating reverse motion errors and ensuring high positioning accuracy.

High load capacity and high rigidity: With a 25mm outer diameter screw shaft and an effective number of 2.5×1 turns, it possesses high rigidity, enabling stable operation under heavy loads.

Versatility and environmental adaptability: NSK offers a wide range of screws, from miniature to large, as well as dedicated support units, lock nuts, and other accessories, greatly simplifying the design and installation process.
