The NSK ball screw W2010FA-4-C5T20 has a shaft diameter of 20 mm, a lead of 20 mm, and a precision class of C5. It employs a tubular recirculation (external recirculation) structure and is suitable for positioning and reciprocating motions in general automated equipment.
The W2010FA-4-C5T200 is an NSK FA type pre-finished ball screw, meaning that both ends of the screw shaft have been precision-machined according to NSK standard support units at the factory and can be directly installed and used.
Features of FA type ball screws (finished product) at the shaft end:
Compact design: The FA series nut has a compact structure, saving installation space and is especially suitable for small equipment.
High-precision positioning: C5 grade accuracy, preload design eliminates axial backlash, ensuring high-precision and repeatable positioning.
Low-noise operation: Optimized ball circulation system design reduces operating noise.
Fast delivery: Ample stock of standard models allows for quick fulfillment of customer needs.
Typical application industries for NSK FA type shaft-end finish quality control circulating ball screws:
I. Automation equipment industry
II. CNC machine tools and machining equipment
IV. Medical and laboratory equipment
V. Packaging and printing equipment
VI. Robotics and intelligent equipment
