The W1603FA-7PGX-C5Z32 is an NSK FA type pre-finished ball screw, meaning both ends of the screw shaft have been precision-machined to NSK standard support units at the factory and are ready for direct installation. The NSK ball screw W1603FA-7PGX-C5Z32 has a 16 mm shaft diameter, 32 mm lead, and a C5 accuracy class. It features an end-cap type recirculation structure, suitable for high-speed, long-stroke linear motion applications. The shaft ends are pre-machined for direct installation.
The core advantages of NSK FA type 16×32 specification shaft-end finished ball screws:
• High lead and high speed: 32mm lead, high feed efficiency, suitable for rapid feed scenarios
• High preload and rigidity: Preload design eliminates backlash, significantly improving axial rigidity, suitable for high-precision positioning
• Low noise with end cap: End cap type circulation structure, smooth and low noise operation, suitable for medium and high speed conditions
• Compact and lightweight: FA series universal design, small size and easy integration, suitable for small equipment
Typical application scenarios for small diameter + high lead ball screws:
I. Automation equipment / Industrial field
II. Semiconductor & electronic manufacturing equipment
III. Light machine tools / Auxiliary feed mechanisms
IV. Medical equipment / Precision instruments
V. Robots and electric actuators
VI. Light-load high-speed special equipment
