Sill Bearing
In the vast landscape of mechanical engineering, few components are as universally essential as the 6202 Ball Bearing. As a leading China 6202 Ball Bearing supplier, SILL BEARING FACTORY understands that this specific model—a deep groove ball bearing with a 15mm bore, 35mm outer diameter, and 11mm width—serves as the backbone of countless industrial and consumer applications. From the electric motors that power our homes to the sophisticated conveyor systems in automated warehouses, the 6202 bearing is a master of versatility, handling both radial and axial loads with exceptional efficiency.
The global demand for high-precision 6202 bearings is currently witnessing an unprecedented surge. This is driven by the rapid expansion of Industry 4.0, where high-speed rotations, low friction, and long-term durability are non-negotiable requirements. As global supply chains evolve, the role of a reliable China ball bearing supplier becomes critical in bridging the gap between high-volume manufacturing needs and the stringent quality standards required by international markets such as Europe, North America, and Southeast Asia.
Modern 6202 bearings are moving beyond standard chrome steel (GCr15). We are seeing a rise in high-nitrogen steels and ceramic hybrids for extreme environments, offering higher heat resistance and corrosion protection.
The "Smart Bearing" era is here. Integrating sensors to monitor vibration, temperature, and lubrication in real-time allows for predictive maintenance, reducing downtime in heavy industrial settings.
Eco-friendly manufacturing processes and low-friction designs contribute to energy efficiency. Suppliers are now focusing on carbon-neutral production and recyclable packaging for global compliance.
The 6202 series is evolving to meet the needs of the Electric Vehicle (EV) revolution. With motors spinning at much higher RPMs than traditional internal combustion engines, the demand for "low-noise, high-speed" (Z3V3 or Z4V4 grade) 6202 bearings has skyrocketed. As a top-tier China 6202 ball bearing factory, we have invested heavily in automated grinding and assembly lines that utilize AI-driven vision inspection systems to ensure every unit meets the "Zero Defect" target.
Where exactly do you find the 6202 bearing? Its footprint is everywhere. In residential sectors, it is the silent force inside washing machine motors, ceiling fans, and vacuum cleaners. Its ability to operate quietly is paramount for household comfort.
In the automotive sector, the 6202 is frequently utilized in alternators, tensioners, and small electric auxiliary motors. The durability of the seal—whether it's ZZ (metal shield) or 2RS (rubber seal)—is tested against road salt, moisture, and temperature fluctuations.
For industrial automation, 6202 bearings are found in high-precision encoders, small gearboxes, and conveyor rollers. In these scenarios, procurement managers prioritize "Total Cost of Ownership" (TCO), seeking bearings that offer the longest service life to minimize the labor costs associated with replacement.
Procuring 6202 bearings is no longer just about the lowest price. International buyers from the USA, Germany, and Japan are looking for:
Located in the heart of China's manufacturing powerhouse, SILL BEARING FACTORY offers a strategic advantage that few can match. Our facility is situated in the beautiful and affluent Hangzhou Bay New Zone. This location is a masterstroke of logistics, being equidistant to two of the world's busiest maritime gateways: Shanghai Port and Ningbo Port.
Proximity to these ports means significantly reduced inland transport times and costs, a benefit we pass directly to our international clients. Furthermore, our proximity to the Hangzhou-Ningbo Expressway, the 329 State Line, and the Hangzhou-Ningbo Railway Line ensures that our supply chain remains resilient and fast. For our clients visiting from abroad, we are only 90 minutes away from Hangzhou Xiaoshan Airport or Ningbo Lishe Airport, making us one of the most accessible China 6202 ball bearing suppliers for factory audits and technical consultations.
Original Factory Profile: 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. Besides, it owns the advantage of transportation, as it only takes about 90 minutes to go to Hangzhou Xiaoshan Airport or Ningbo Lishe Airport.
We don't just manufacture bearings; we engineer reliability. Our 6202 production lines utilize Fully Automated Grinding Technology. This minimizes human error and ensures that every ring, ball, and cage meets the exact tolerances required by P6 or P5 precision classes. Our testing center is equipped with S0910 vibration testers, roundness measuring instruments, and digital metallographic microscopes.
By choosing SILL BEARING as your 6202 ball bearing supplier, you are gaining a partner that utilizes AI-integrated data management to track every production batch from raw steel to the final packaged box. This level of transparency is what modern industrial procurement demands.
| Feature | Specification |
|---|---|
| Bore Diameter (d) | 15 mm |
| Outer Diameter (D) | 35 mm |
| Width (B) | 11 mm |
| Dynamic Load Rating (Cr) | 7.8 kN |
| Static Load Rating (Cor) | 3.75 kN |
| Limiting Speed (Grease) | 15,000 - 22,000 RPM (Depending on Seal) |
Understanding these specs is vital for engineers. A 6202-ZZ bearing provides excellent protection against dust, while the 6202-2RS offers a superior seal against moisture, albeit with a slightly lower speed limit due to friction. We also provide 6202-C3 variants which feature increased internal clearance to account for thermal expansion in high-temperature environments, such as ovens or high-speed spindles.
As a professional 6202 ball bearing supplier, we offer customization in lubrication as well. Depending on your application—whether it's food-grade machinery or low-temperature outdoor equipment—we can apply specialized greases from Mobil, Kyodo Yushi, or Shell to ensure optimal performance.
