The NSK W1603FA-2-C3T5 FA type C3 precision ball screw has a 16mm shaft diameter and a 5mm lead. The FA W1603FA-2-C3T5 shaft-end finished ball screw uses a tube circulation system and a flange-type nut design, making it easy to install and run smoothly. It is commonly used in industrial automation, robotics, and medical equipment.
NSK A-series precision ground ball screws feature:
High precision: Utilizing a grinding process, lead error is controlled within the micron level, commonly achieving C3 precision, suitable for high-precision positioning and repeatable positioning applications.
High rigidity: Axial backlash can be eliminated through preloading, significantly improving system rigidity and vibration resistance, ensuring machining or motion stability.
Long lifespan: The raceway is quenched and precision ground, resulting in high surface hardness, low roughness, minimal wear, and good long-term precision retention.
Strong standardization and versatility: The A-series is a standard NSK shaft-end finished product with a unified flange nut structure and standardized installation dimensions, facilitating selection and replacement.
