Sill Bearing
In the intricate world of mechanical engineering, the 6203 bearing stands as one of the most versatile and indispensable components ever designed. As a prominent China 6203 bearing manufacturer, we have witnessed the explosive growth in demand for this specific series. With a 17mm bore, 40mm outer diameter, and 12mm width, the 6203 series provides the perfect balance between load-bearing capacity and space efficiency.
Today, the global 6203 bearing market is evolving. From high-speed electric vehicle motors to precision medical equipment, the requirements for low noise, high rotational accuracy, and long-term durability have never been higher. Our factory utilizes high-carbon chromium steel (GCR15) and advanced heat treatment processes to ensure every unit meets international ISO standards, satisfying the rigorous demands of global procurement officers.
Annual Production Capacity: 50 Million+ Units
Tolerance Grade: P0, P6, P5, P4
Noise Level: Z1, Z2, Z3, Z4
Vibration Level: V1, V2, V3, V4
Modern devices require smaller footprints. We are optimizing the internal geometry of 6203 bearings to maximize load ratings without increasing physical dimensions.
Global enterprises are shifting toward sustainable sourcing. Our production lines utilize energy-efficient machinery and eco-friendly lubricants (Grease: Kyodo Yushi, Shell, Mobile).
The rise of Industry 4.0 means bearings are now part of IoT systems. We offer integrated sensor solutions to monitor heat and vibration in real-time.
Global procurement specialists from the USA, Germany, and Japan are increasingly turning to Chinese manufacturers for their 6203 bearing needs. The reason is not just cost—it's the complete supply chain ecosystem. Our factory, located in the Hangzhou Bay New Zone, represents the pinnacle of this efficiency.
Being close to Shanghai and Ningbo Ports reduces transit times and shipping costs significantly, allowing for "Just-in-Time" delivery models for our international partners.
We source raw GCR15 steel from top-tier Chinese mills, ensuring consistency in hardness (HRC 60-65) and fatigue life that rivals European brands.
Whether you need specialized seals (ZZ, 2RS, RZ), specific internal clearances (C3, C4), or custom branding, our engineering team can adapt our 6203 series to your specific application.
The 6203 bearing is a "workhorse" across various sectors. Understanding where it is used helps our clients specify the right technical configurations:
| Industry Sector | Typical Application | Specific Requirement |
|---|---|---|
| Automotive | Alternators & Air Conditioning Compressors | High temperature grease and high-speed stability. |
| Home Appliances | Washing Machine Motors & Fans | Ultra-low noise (Z3/Z4) and minimal vibration. |
| Power Tools | Electric Drills & Circular Saws | Effective sealing against dust and debris (2RS). |
| Agriculture | Conveyor Systems & Harvesters | High load capacity and corrosion resistance. |
SILL BEARING FACTORY, is located in the beautiful and affluent place named Hangzhou Bay New Zone, which is not only close to the two biggest ports of China—Shanghai port and Ningbo Port, but also adjacent to Hangzhou—Ningbo Expressway, 329 State Line and Hangzhou- Ningbo Railway Line.
