Stainless linear rail is a linear motion guide made of stainless steel. Compared with general steel guide, the cost of stainless steel linear guide will be higher. So why do we use stainless steel linear guide in industrial manufacturing?
1. Material characteristics
First of all, let's understand from the basic components of stainless steel. Stainless steel is an alloy based on iron. The alloy elements include chromium, nickel, carbon, titanium, etc. Among them, chromium is the key to stainless steel not rusting. It can form a protective self-repairing oxide film on the surface of stainless steel. So many times, we often use chrome plating, zinc plating or nickel plating when choosing surface treatment. Of course, zinc plating and nickel plating are more often chosen because they are cheaper.
2. Reasons for Using Stainless Linear Rail
Excellent Corrosion Resistance and Oxidation Resistance: Stainless linear rails can operate stably for a long time in harsh environments such as humidity, dust or chemical corrosion, greatly extending the service life of the equipment.
Higher Precision and Stability: Its sophisticated design and manufacturing process ensure the stability and accuracy of the guide during movement, thereby improving the overall performance of the equipment. In addition, the thermal expansion coefficient of stainless steel is low, so that the guide can maintain stable performance even in high temperature environments.
Smaller Friction Coefficient and Lower Noise Level: High-quality materials and fine surface treatment process enable the guide rail to reduce friction and wear during sliding, reduce noise pollution, and improve the comfort of equipment.
Easy Installation and Maintenance: The compact design and standardized interface make the installation process more convenient and quick. At the same time, due to its excellent durability and stability, the maintenance cost is relatively low.
3. Application Scenarios of Stainless Linear Rails
Stainless steel materials are widely used in linear guides, mainly because stainless steel has good corrosion resistance, wear resistance and strength, and can maintain stable performance in harsh working environments. Among the stainless steel materials that can be used in linear guides, the most common ones are 440, 304, and 420:
- 440 High carbon stainless steel, with high hardness and good wear resistance, is widely used in high-load and high-speed occasions, such as machine tools, automated production lines, and precision instruments.
- 304 Common stainless steel material, with good corrosion resistance and welding performance, is widely used in some low-load and medium-speed occasions, such as medical equipment, food processing equipment, etc.
- 420 Stainless steel materials with high hardness and good wear resistance are suitable for high-load and high-speed occasions, such as roller linear guides and ball linear guides.
Summary
Stainless linear rails can meet the high requirements of modern industry for automation control and promote the development of intelligent industrial production. If you have any questions about related products or purchase needs, please feel free to contact us!
