Sill Bearing
High-performance components for diverse industrial applications.
The 6317 deep groove ball bearing is an essential pillar of modern heavy machinery. With an inner diameter of 85mm, an outer diameter of 180mm, and a width of 41mm, the 6317 series is engineered to support high radial loads while maintaining stability at significant speeds. Globally, the demand for precision-grade 6317 bearings has surged due to the rapid expansion of renewable energy sectors, particularly in wind turbine gearboxes and large-scale industrial electric motors.
In the current industrial landscape, enterprises in Europe, North America, and Southeast Asia are looking for more than just a component; they are seeking reliability and durability. The 6317 bearing serves as the heart of transmission systems in mining equipment, agricultural machinery, and power generation units. As industries transition toward "Industry 4.0," the 6317 model has evolved to incorporate advanced sealing technologies and specialized heat treatments to withstand harsh environmental conditions.
Merging material science with AI-driven manufacturing processes.
Modern 6317 factories are moving beyond standard GCr15 steel. High-nitrogen steels and ceramic hybrid options are becoming the norm for high-temperature and high-corrosion environments.
AI-integrated production lines allow for real-time monitoring of tolerance levels. Our China factory utilizes automated grinding and assembly to ensure 100% consistency across every 6317 batch.
Sustainability is driving the development of biodegradable lubricants and low-friction cages, reducing the carbon footprint of heavy industrial operations worldwide.
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.
This strategic positioning offers unparalleled logistical advantages for global procurement. Besides, it owns the advantage of transportation, as it only takes about 90 minutes to go to Hangzhou Xiaoshan Airport or Ningbo Lishe Airport. For international buyers, this means reduced lead times, lower shipping costs, and the ability to conduct rapid factory audits and quality inspections.
"Being at the epicenter of China's manufacturing hub allows us to leverage high-tech supply chains while maintaining the cost-efficiencies that global '6317 bearing factory' seekers demand."
Solving complex rotation challenges across every major industry.
Used in 200kW+ industrial motors where high radial rigidity is required to maintain shaft alignment under peak torque loads.
Sealed 6317-2RS variants are essential in conveyor pulleys and crushers, preventing dust and slurry from compromising the rolling elements.
Large-scale centrifugal fans rely on the 6317's low noise and vibration characteristics to ensure long-term, maintenance-free operation in commercial buildings.
Tractors and harvesters utilize 6317 bearings in transmission gearboxes to handle the rugged terrain and varying seasonal loads.
The high thermal stability of our 6317 bearings makes them ideal for roller tables in hot rolling mills where ambient temperatures are extreme.
From hydro-turbines to emergency diesel generators, the precision of the 6317 ensures uninterrupted power flow and grid stability.
What sets our factory's production apart from generic alternatives.
Procurement for 6317 bearings requires a balance of price, quality, and compliance. As a leading China 6317 Bearing Factory, we provide:
In the world of mechanical engineering, the 6317 bearing is often referred to as a "medium-heavy" series component. Unlike the 6000 or 6200 series, the 6300 series (including 6317) features a larger ball diameter and deeper grooves. This design allows it to absorb much higher energy loads, making it indispensable for heavy-duty drive shafts. As a premier 6317 Bearing Factory, we understand that the failure of a single bearing can lead to thousands of dollars in downtime. That is why our quality control protocols include ultrasonic flaw detection and vibration analysis as standard procedures.
Recent data indicates that the global ball bearing market is projected to grow significantly by 2030. Much of this growth is driven by the automation of warehouses and the rise of electric vehicles. For the 6317 model specifically, the largest demand comes from the "Belt and Road" infrastructure projects where massive machinery is deployed in remote locations. These environments require bearings that can operate without frequent maintenance, pushing us to innovate in long-life lubrication technology.
Working with a factory in the Hangzhou Bay New Zone provides more than just a product. It provides a logistical nexus. Our proximity to the Shanghai and Ningbo Ports allows for "Just-In-Time" delivery models for our international clients. This reduces the need for expensive inventory stockpiling, allowing our partners to maintain leaner operations while knowing that a reliable supply of 6317 bearings is always available.
For engineers drafting specifications, the 6317 typically adheres to the following parameters in our production line:
From micro-bearings to massive roller systems.
