The Stainless Steel Linear Shaft is a high-precision, high-strength transmission component made of high-quality stainless steel, possessing excellent corrosion resistance, wear resistance, and mechanical properties. It is widely used in automation equipment, CNC machine tools, semiconductor equipment, medical equipment, food machinery, packaging machinery, and other fields, suitable for applications requiring high-precision linear motion and long-term stable operation. Its rational structural design, smooth surface, and high precision allow it to meet the demands of various harsh working environments.
Product Features
Superior Material: Made of 304 or 316 stainless steel, highly corrosion-resistant, suitable for harsh environments such as humid and acidic/alkaline conditions.
High Precision: Precision-machined, shaft diameter tolerance is strictly controlled within ±0.005mm, ensuring linear motion accuracy.
Surface Treatment: Surface polished, ground, or hardened (e.g., hard chrome plating), resulting in low surface roughness (Ra≤0.4μm), reducing the coefficient of friction and extending service life.
High Strength and Rigidity: The material undergoes heat treatment, achieving a hardness of HRC58-62, providing excellent bending and vibration resistance.
Low Coefficient of Friction: When used with linear bearings or sliding bushings, it enables smooth, low-noise motion.
Customizable: Available in various diameters and lengths, supporting custom sizes and surface treatments.
Easy Installation: Standardized structural design facilitates integration with various mechanical components.

Installation and Maintenance
1. Installation Precautions:
- Ensure the mounting surface is flat to avoid shaft bending or eccentricity.
- Use specialized tools to install bearings or bushings; avoid direct impact to the shaft.
- Fit tolerances should meet design requirements; clearance or transition fits are recommended.
2. Maintenance Recommendations:
- Clean the shaft surface regularly to prevent dust or foreign matter from adhering.
- Apply grease regularly according to actual operating conditions.
- Avoid overloading to prevent damage or breakage of the shaft surface.
- Apply rust-preventive oil for protection before long-term storage.
Packaging, Transportation, and Precautions
Packaging and Transportation
1. Packaging: The shaft surface is wrapped with an anti-rust film, and protective caps are added to both ends. It is packaged in a hard cardboard box or wooden crate to prevent collisions during transportation.
2. Transportation: Avoid heavy pressure, severe vibration, or rain. Store in a dry and ventilated place.
Precautions
1. Do not use sharp tools to scratch the shaft surface.
2. Before installation, check the shaft for bending or damage, and confirm that the precision meets the requirements.
3. When used in high-temperature or corrosive environments, it is recommended to use 316 stainless steel and perform regular maintenance.
