C5 precision positioning ball screw W1504FA-6G-C5T20 NSK FA type

The NSK W1504FA-6G-C5T20 is a C5 precision ball screw of the FA type, with a 15mm shaft diameter and a 20mm lead. The FA type finished shaft end ball screw uses an end cap circulation system and is compatible with UPFC and USFC type nuts, ensuring easy installation and smooth operation. The shaft end is pre-machined and ready for direct assembly.
Key features of the NSK FA End Cap Type ball screw:
Circulation method (end cap type): Utilizes an end cap structure, resulting in a compact nut design suitable for short lead and miniaturized designs.
Pre-machined shaft: The screw end is precision-machined, eliminating the need for further processing by the user and significantly shortening the equipment assembly cycle.
High precision and high rigidity: Although compact, the FA series typically offers excellent precision (e.g., C5 grade) and axial rigidity, meeting the requirements for precision conveying and positioning.
Applicable scenarios: Small machinery, conveying equipment, medical devices, packaging machines, and other automated equipment with limited installation space.
Applications of W1504FA-6G-C5T20 Grinding Grade Ball Screw: 
Semiconductor manufacturing equipment, precision measuring instruments, electronic component assembly equipment, automated packaging, and medical devices. Particularly suitable for applications requiring both compact space and high loads.
Customization Services: We offer non-standard customized ball screws, supporting design and processing based on provided drawings to meet the personalized needs of precision transmission and automation equipment.
