The NSK W2507SA-3P-C5Z6 SA type ball screw has a 25mm shaft diameter and a 6mm lead, classifying it as a small-lead ball screw. The SA W2507SA-3P-C5Z6 shaft-end finished ball screw uses a tubular circulation design and features a flange-type nut, ensuring convenient installation and smooth operation. It is commonly used in machine tool equipment.
W2507SA-3P-C5Z6 Ball Screw Core Features and Advantages:
Ready to Use: The SA type shaft end is precision-machined, requiring no secondary processing by the user. It can be directly matched with NSK WBK/WBN series support units, significantly shortening the assembly cycle and reducing installation costs.
Zero Backlash High Precision: The single-nut interference preload design (P) completely eliminates axial backlash. C5-level precision ensures extremely low positioning error, suitable for precision positioning scenarios requiring frequent forward and reverse rotation.
Zero Backlash High Precision: Compact Design: The single-nut design saves more installation space than double-nut designs, making it suitable for smaller equipment. Meanwhile, the preload (P) provides sufficient rigidity to meet general load requirements.
In Stock: As standard NSK stock items, they offer short delivery times and allow for rapid response to equipment manufacturing and maintenance needs
Applications of the W2507SA-3P-C5Z6 finished ball screw:
Precision machine tools: Machining centers, CNC lathes, grinding machines, etc.
Automation equipment: Semiconductor manufacturing equipment, testing instruments, precision positioning platforms
Precision manufacturing: Electronic component processing, optical equipment, medical equipment
Suitable for applications requiring high-precision positioning, especially for mass production and standardized equipment.
