Sill Bearing
The 6902 2RS bearing (15mm x 28mm x 7mm) represents a critical component in the modern industrial landscape. As a thin-section deep groove ball bearing, its unique dimensions allow for significant space savings without compromising rotational speed or precision. Globally, the demand for high-performance bearings has surged, driven by the rapid expansion of electric vehicles (EVs), sophisticated medical devices, and high-end consumer electronics.
In the current commercial climate, 6902 2RS bearings are categorized as essential high-growth components. European and North American markets are increasingly focusing on "Total Cost of Ownership" (TCO), leading them to seek manufacturers who can balance extreme durability with competitive pricing. As a leading China 6902 2RS Bearing Factory, we satisfy this global hunger by integrating advanced heat treatment processes and superior seal technology (2RS - Double Rubber Seals) to ensure longevity in harsh environments.
The bearing industry is shifting towards Smart Manufacturing and Greener Materials. Low-torque 6902 2RS bearings are now being developed with bio-degradable lubricants and ceramic ball hybrids to meet the stringent energy-saving requirements of 2024 and beyond.
Procurement officers today demand more than just a product. They need supply chain resilience, transparent quality control (ISO 9001:2015), and the ability to customize seal colors and grease types for specific regional climates from Siberia to the Sahara.
Integrating AI-based optical sorting and vibration analysis allows us to guarantee zero-defect batches. Our automated lines monitor the noise levels (Z1, Z2, Z3 grades) of every 6902 2RS bearing before it leaves the factory floor.
The versatility of the 6902 2RS makes it a favorite across multiple sectors. Its double-sealed architecture protects the internal raceway from dust, water, and contaminants, making it ideal for:
| Bore Diameter (d) | 15 mm |
| Outer Diameter (D) | 28 mm |
| Width (B) | 7 mm |
| Seal Type | Rubber Sealed (2RS) |
| Material | Chrome Steel (GCr15) |
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.
Our strategic location translates directly into cost savings for our clients. By reducing domestic logistics time and costs, we can offer faster turnaround times for high-volume 6902 2RS orders. Furthermore, our factory leverages the industrial cluster of the Yangtze River Delta, accessing the highest quality raw steel and the latest engineering talent.
Choosing the right China 6902 2rs Bearing Manufacturer involves understanding the nuances of material science and precision engineering. At our factory, we don't just produce metal parts; we engineer solutions. The 6902-2RS designation signifies a bearing that is built to last, featuring deep raceway grooves that are honed to a mirror finish. This reduces friction and heat generation, which is the primary cause of bearing failure in high-speed applications.
We primarily utilize high-carbon chromium steel (GCr15), which provides the necessary hardness for fatigue resistance. For specialized industries like food processing or marine environments, we offer 6902 2RS variants in Stainless Steel (AISI 440C or 304). The 2RS rubber seals are made from high-quality Nitrile Rubber (NBR), capable of withstanding temperatures from -20°C to +120°C, ensuring the internal grease remains uncontaminated.
Our manufacturing lines are capable of producing bearings up to P5 and P4 precision grades. In the global marketplace, where automated assembly is standard, the consistency of dimensions is non-negotiable. Every 6902 2RS bearing undergoes rigorous testing for radial play and axial clearance to ensure it fits perfectly into your assembly, whether it's a drone motor or a high-end mountain bike hub.
As the industry moves toward sustainability, our factory has implemented closed-loop water cooling systems and energy-efficient induction hardening machines. We believe that being a top-tier China 6902 2RS Bearing Factory means taking responsibility for the environment while delivering the high-tech performance our clients expect. Our R&D team is constantly exploring low-friction seal designs that can save up to 15% more energy compared to standard 2RS seals.
