W2008FA-4-C5T20 NSK FA Type External Circulation Ball Screw

The NSK W2008FA-4-C5T20 is a high-precision, large-lead FA-type external circulation ball screw manufactured by NSK Japan. The W2008FA-4-C5T20 features a 20mm shaft diameter, 20mm lead, C5 precision grade, and a low backlash design, resulting in excellent load-bearing capacity and high positioning repeatability.

Features of the W2008FA-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.
