Ningbo Sanya Bearing Co., Ltd. was established in 1994 and is located in the core area of ​​the Yangtze River Delta. It enjoys a high reputation in the bearing industry for its high-quality products. In particular, its 6000 series double contact sealed deep groove ball bearings are highly regarded for their excellent sealing performance and durability. These bearings are designed to provide an excellent seal, effectively preventing external contaminants such as dust, dirt and moisture from entering the bearing, significantly extending the service life of the bearing.The double contact seal structure of the 6000 series bearings is a distinctive feature. Double contact seal means that the bearing is equipped with two contact seal rings. These seal rings can not only prevent contaminants from entering, but also effectively retain the lubricant inside the bearing, thus ensuring the long-term stable operation of the bearing. This design is particularly suitable for applications that operate in harsh operating environments, such as agricultural machinery, construction equipment and outdoor equipment, where bearings are often exposed to higher risks of dust and moisture.Ningbo Sanya Bearing Co., Ltd. not only focuses on quality in product design, but also implements strict quality control measures during the production process. The company has introduced advanced manufacturing equipment and testing instruments to ensure that each batch of bearings meets or exceeds industry standards. In addition, Ningbo Sanya also pays attention to the selection of raw materials. The combination of high-quality steel and precision processing technology makes the bearings it produces have higher strength and wear resistance.As the global market's demand for high-performance bearings continues to increase, Ningbo Sanya Bearing Co., Ltd. has continued to expand its production capabilities and is committed to technological innovation to meet customers' customized needs. Whether in the field of OEM (original equipment manufacturing) or ODM (original design manufacturing), Ningbo Sanya has won widespread recognition and trust from customers for its reliable product quality and excellent service.

Deep groove ball bearings are one of the most widely used bearings in various industries due to their simple structure and versatile functions. Deep groove ball bearings consist of inner and outer rings, cages and rolling elements. The rolling elements in the bearing are usually spheres, which are fixed in the correct position by the cage. In addition, deep groove ball bearings are equipped with seals or dust covers to protect the inside of the bearing from contaminants. The so-called "deep groove" refers to the depth of the raceway grooves in the inner and outer rings, which can accommodate the balls and enable them to run smoothly. This design not only enables the bearings to withstand radial loads, but also axial loads within a certain range, so they perform well in various applications.Another important feature of deep groove ball bearings is their low friction and high speed capabilities. This makes them very suitable for applications that require high speed operation and long life. For example, in the automotive industry, deep groove ball bearings are widely used in wheels, transmissions and engines. Their low friction characteristics help reduce fuel consumption and extend the service life of vehicles. Likewise, in industrial machinery, these bearings are used in a variety of rotating equipment, such as motors, compressors, and pumps, to improve the efficiency and reliability of the equipment.Deep groove ball bearings are relatively simple to maintain because they are usually pre-lubricated, and many models are equipped with sealing devices that can effectively prevent the leakage of lubricants and the ingress of external contaminants. This design reduces maintenance costs and extends the service life of the bearings.
