This chrome rod is mirror polished and designed to provide smooth and stable performance in both hydraulic and pneumatic systems.
Manufactured from black round steel bars, the rod goes through advanced processing steps such as peeling, grinding, and chrome plating. The result is a high-gloss finish with Ra0.20μm and f7 tolerance, which ensures smooth motion and reduced cylinder wear.
With its hard chrome layer, this chrome rod resists rust, mechanical stress, and surface wear, extending the lifespan of actuators and cylinders. It is suitable for use in industrial robotics, packaging machines, and automated production lines.
Available in standard and custom sizes, it meets international demands and is backed by reliable quality assurance.
Features:
1. High precision.
2. Made by best raw material.
3. Quality stable and uniformity.
4. Better packing protection.
5. Perfect after-sales service
