W1503FA-7PG-C5Z20 flange type nut preloaded ball screw NSK FA

The W1503FA-7PG-C5Z20 is a typical NSK FA type finished shaft end ball screw with a 15mm shaft diameter and 20mm lead, manufactured using a precision grinding process. The FA W1503FA-7PG-C5Z20 C5 precision ball screw features an end cap circulation design with a flange-type nut, ensuring convenient installation and smooth operation. It is commonly used in industrial automation, robotics, and medical equipment.
NSK FA type finished shaft end ball screw is a standard ball screw series from NSK (Japan). 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 NSK FA type end cap ball screws:
Pre-machined 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 grade precision, combined with P preload, achieves micron-level positioning accuracy.
Compact Design: Smaller nut outer diameter saves installation space, suitable for small, precision equipment.
Reliable Lubrication: Standard pre-lubricated 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 quick response to demand.
Applications of W1503FA-7PG-C5Z20 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 ball screw customization, supporting design and processing based on provided drawings to meet the personalized needs of precision transmission and automation equipment.
