The NSK W2513FA-2-C5T20 is a finished ball screw with a flanged single nut, belonging to the FA type for industrial automation equipment.
The W2513FA-2-C5T20 high-lead ball screw features standard machined ends for easy installation and is suitable for automation equipment and precision linear drive systems requiring high speed response and smooth operation.
The main features of the W2513FA-2-C5T20 external circulation ball screw are as follows:
High positioning accuracy: Accuracy class up to C5, precision ground for smooth operation.
Zero axial backlash: Achieved through interference ball preload (P-type), resulting in zero axial backlash, high rigidity, and suitability for bidirectional precision positioning.
Compact structure: Flange-type single nut design saves installation space.
Wide applicability: Designed specifically for industrial automation equipment (FA series), commonly found in CNC machine tools, industrial robots, automotive equipment, and precision manufacturing lines.
The NSK W2513FA-2-C5T20 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.
