In the heart of modern machinery, the 6306 deep groove ball bearing stands as a cornerstone of mechanical efficiency. With its standard dimensions of 30mm bore, 72mm outer diameter, and 19mm width, the 6306 model is more than just a component; it is a vital organ in the industrial world. As a leading China 6306 bearing supplier, we recognize that the global demand for this specific series is driven by its exceptional versatility. Whether it is a high-speed electric motor in a European manufacturing plant or a rugged transmission system in an American agricultural tractor, the 6306 bearing provides the necessary support for both radial and axial loads.
The global bearing market is projected to grow significantly, with deep groove ball bearings like the 6306 series taking a lion's share of the volume. This growth is fueled by the rapid electrification of vehicles and the expansion of automated production lines.
We are moving towards "Smart Bearings." Integration of sensors to monitor vibration, heat, and lubrication levels is transforming how 6306 bearings are utilized in Industry 4.0 environments.
Reducing carbon footprints is a priority. Our factory focuses on low-friction 6306 variants that contribute to energy efficiency in high-rotation applications, lowering the overall power consumption of machines.

Procurement managers across the globe—from the industrial hubs of Germany to the tech corridors of Southeast Asia—face a common challenge: balancing cost with uncompromising reliability. When sourcing from a 6306 bearing factory in China, buyers look for consistency. A single failure in a 6306 bearing can halt an entire production line, leading to thousands of dollars in downtime.
Pro Tip for Buyers: Always verify the clearance (C3 vs. CN) and sealing types (ZZ vs. 2RS) of your 6306 bearings. Our factory provides detailed material reports (GCr15 Chrome Steel) and noise testing certificates (Z1, Z2, Z3 grades) to ensure transparency in every shipment.
SILL BEARING FACTORY is strategically located in the Hangzhou Bay New Zone, a prime economic hub. Our proximity to the two largest ports in China—Shanghai Port and Ningbo Port—gives our clients a significant logistical edge. We aren't just a supplier; we are a partner in your supply chain.
Being adjacent to the Hangzhou-Ningbo Expressway and the 329 State Line means we can move products from our production floor to the container ships in record time. For international clients, our location is just 90 minutes from Hangzhou Xiaoshan Airport or Ningbo Lishe Airport, making factory audits and visits seamless.
To understand why the 6306 is preferred by global engineers, one must look at its load ratings. A standard 6306 bearing typically handles a Dynamic Load Rating (Cr) of approximately 26.7 kN and a Static Load Rating (Cor) of 14.9 kN. This high load-to-size ratio is achieved through precision heat treatment processes at our China factory.
The industry is currently shifting towards high-precision P6 and P5 grades for the 6306 series to accommodate the requirements of high-efficiency motors. By reducing internal friction, these bearings not only last longer but also reduce the heat generated during operation, which is the primary cause of lubricant degradation.
As 6306 bearing suppliers, we are investing heavily in "Green Manufacturing." Our facility uses recycled water systems for cooling and energy-efficient heat treatment furnaces. For global enterprises looking to meet their ESG (Environmental, Social, and Governance) targets, partnering with SILL BEARING ensures that your components are produced with a focus on sustainability.
