NSK W2009FA-4-C5T20 FA Type Large Lead Ball Screw Micro Gap Ball Screw

The NSK W2009FA-4-C5T20 is a high-precision, large-lead FA-type external circulation ball screw manufactured by NSK Japan. The W2009FA-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 W2009FA-4-C5T20 Shaft-End Finished Ball Screw:

Conduit-Type External Circulation: Utilizes a conduit-type external circulation ball screw system, allowing for smooth ball circulation within a conduit outside the nut, resulting in a smoother path.

Precise Clearance Control: Axial clearance is only approximately 0.005mm, balancing high-precision positioning with 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 making it 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.

Applications of NSK 20×20 FA type finished ball screws with shaft end:
