The NSK W2509FA-4-C5T25 ball screw is a C5-grade precision FA-type ball screw with a 25mm shaft diameter, 25mm lead, and a finished shaft end. It features single-nut preload, axial clearance ≤0.005mm, high rigidity, and strong load-bearing capacity, making it suitable for medium-to-high load automated equipment such as CNC machine tools and robots.
Features of the NSK W2509FA-4-C5T25 Finished Ball Screw:
High Precision: C5 precision ensures minimal lead error over long strokes.
High Transmission Efficiency: The rolling motion of the balls between the screw and nut results in low friction loss and higher efficiency than sliding screws.
Good Stability and Durability: NSK's proprietary manufacturing processes and materials guarantee stability under high speed and heavy loads.
The NSK W2509FA-4-C5T25 ball screw is commonly used in:
CNC Machine Tools: Feed axes of CNC machining centers, lathes, and milling machines.
Automated Production Lines: Robotic arms and material handling robots.
Precision Measuring Instruments: Coordinate measuring machines, etc.
