THK W2011FA-3P-C5Z20 High Rigidity Ball Screw C5 Precision Ball Screw

The NSK W2011FA-3P-C5Z20 FA type ball screw has a 20mm shaft diameter and a 20mm lead, classifying it as a large-lead ball screw. The FA W2011FA-3P-C5Z20 finished-end ball screw features an external circulation structure and a flange-type nut design, ensuring convenient installation and smooth operation. It is commonly used in industrial automation equipment.

NSK W2011FA-3P-C5Z20 Ball Screw Features:

High Precision (C5 grade): Manufactured using a grinding process, resulting in small lead error and high repeatability, suitable for CNC machine tools and precision positioning systems.

Good Rigidity: Axial backlash can be eliminated through preloading, improving overall rigidity and making it suitable for handling cutting forces or dynamic loads.

High Load Capacity: Multiple balls bear force simultaneously, resulting in uniform load distribution and the ability to withstand large axial loads.

Standardized Shaft End (FA type): The shaft end is pre-machined, allowing direct installation of standard support seats (such as BK/BF) without secondary machining. External circulation (ball return type): The balls roll inside the nut to bear the load, and then return to the circulation channel through an external ball return tube. The structure is mature and stable, and suitable for normal industrial working conditions.
