The W2006FA-1P-C5Z10 is an NSK small-lead ball screw, belonging to the A series FA type. It has a screw diameter of 20mm, a lead of 10mm, C5 precision, and a flange-type nut. It is a pre-machined ball screw with a finished shaft end.
NSK's pre-machined FA type ball screws are a standard ball screw series from NSK (Japan Precision Machinery). The shaft end is precision-machined and can be directly installed and used, eliminating the need for additional shaft end machining by the user and significantly shortening the equipment assembly cycle.
Features of the Pre-machined FA Type Ball Screw:
Finished Shaft End Design: The shaft end is pre-machined (threads, keyways, etc.) at the factory, allowing for direct assembly and shortening the equipment development cycle.
High Precision Performance: C5 precision, combined with P preload, enables high positioning accuracy.
Compact Structure: Smaller nut outer diameter saves equipment installation space, suitable for small precision equipment.
Reliable Lubrication: Standard sealed grease supports long-term maintenance; some models can be upgraded to a maintenance-free lubrication system.
Fast Delivery: Commonly used specifications are in stock for rapid response to demand.
