The NSK W2012FA-1P-C5Z10 is a precision-ground ball screw from the FA series, featuring a pre-machined shaft end. It has a 20mm shaft diameter, a 10mm lead, and a C5 precision grade. The W2012FA-1P-C5Z10 external circulation ball screw with zero axial backlash is ideal for precision positioning and automated equipment.
NSK W2012FA-1P-C5Z10 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 tube 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, suitable for routine industrial conditions.
Typical application industries of NSK FA type shaft end finish control circulating ball screws:
I. Automation equipment industry
II. CNC machine tools and machining equipment
IV. Medical and laboratory equipment
V. Packaging and printing equipment
VI. Robotics and intelligent equipment
