NSK W2005FA-2-C5T10 Ball Screw Finished Shaft End Micro Gap Ball Screw

The W2005FA-2-C5T10 is an NSK FA type pre-finished ball screw, meaning that both ends of the screw shaft have been precision-machined to NSK standard support units at the factory and can be directly installed and used. The NSK ball screw W2005FA-2-C5T10 has a shaft diameter of 20 mm, a lead of 10 mm, an accuracy class of C5, and uses a tubular circulation structure, suitable for positioning and reciprocating motions in general automated equipment.
The NSK A-series pre-machined FA 20×10 ball screws feature the following characteristics: 
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. 
Standard stock: Universal specifications, short lead time, and high cost-effectiveness. 
Moderate precision: Commonly C5 grade, meeting general positioning and transmission needs. 
High transmission efficiency: Ball circulation structure, low friction, and smooth operation. 
Selectable rigidity and preload: Supports preload or micro-clearance configurations to adapt to different working conditions. 
Easy maintenance: Supports lubrication replenishment, ensuring stable service life.
Wide application: Suitable for automated equipment, handling mechanisms, and small precision devices.
Typical application industries of NSK FA type shaft end finish 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
