The NSK W2513FA-3P-C5Z25 ball screw is a high-lead precision ball screw with an outer diameter of 25mm and a lead of 25mm. It is 1513mm in length and features C5-grade accuracy and a preload design to achieve zero axial backlash.
Key features of the NSK W2513FA-3P-C5Z25 pre-machined 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 possesses C5-grade accuracy and achieves zero axial backlash through preload, eliminating reverse motion errors to ensure high positioning accuracy.
High load capacity and high rigidity: The 25mm outer diameter and 25mm lead design provide high rigidity, enabling stable operation under heavy loads.
Applications of NSK FA type shaft-end finished ball screws:
CNC machine tools: machining centers, lathes, milling machines, etc.
Automation equipment: industrial robots, automated assembly lines, precision positioning platforms
Semiconductor equipment: wafer handling, testing equipment
Medical equipment: precision medical instruments, diagnostic equipment
Precision measuring instruments: coordinate measuring machines, image measuring instruments
