W2004FA-4-C5T20 Ball Screw Catheter-assisted External Circulation

The NSK W2004FA-4-C5T20 is a micro-backlash precision ball screw with a 20mm outer diameter and 20mm lead. It features an FA-type flange nut structure, a micro-backlash design, standard C5 high precision rating, and external circulation. This ensures smooth, jam-free movement, excellent positioning accuracy, and a compact structure for easy installation.

Features of the W2004FA-4-C5T20 finished ball screw:

External Circulation with Guide Tube: Utilizing a guide tube external circulation ball screw system, the balls circulate smoothly within a guide tube outside the nut, resulting in a smoother path.

Precise Clearance Control: Axial clearance is only approximately 0.005mm, balancing high-precision positioning and smooth movement, avoiding overheating and wear caused by overload.

Compact Structure: The FA series nut has a 30% smaller outer diameter than traditional products, adapting to confined installation spaces and particularly suitable for small automated equipment.

Long Life Design: High-quality bearing steel material + precision heat treatment process, combined with LR3 grease, ensures long-term stable operation.
