W2011FA-4-C5T20 external circulation ball screw NSK precision ball screw

The NSK ball screw W2011FA-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 W2011FA-4-C5T20 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 W2011FA-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 outer diameter is 30% smaller than traditional products, suitable for confined installation spaces, especially ideal 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.
