Basic Parameters Of Deep Groove Ball Bearings

Deep groove ball bearings are one of the most mainstream and versatile rolling bearings in the machinery industry. With outstanding structural versatility and stable operating performance, deep groove ball bearings have been widely adopted in various mechanical transmission and supporting scenarios.

A complete standard deep groove ball bearing is structurally composed of four core components: an outer ring, an inner ring, precision steel balls and a bearing cage. According to the internal rolling element arrangement, deep groove ball bearings can be classified into single-row and double-row structures. Meanwhile, deep groove ball bearings are divided into open-type and sealed-type versions based on different protective and sealing designs.

The open-type deep groove ball bearing has no additional sealing structure, which is suitable for clean and low-dust working environments. In contrast, sealed-type deep groove ball bearings are further categorized into dust-proof sealing and oil-proof sealing types. The dust-proof sealing cover of deep groove ball bearings is made of stamped steel plate, which can block external dust and particulate impurities from entering the raceway of deep groove ball bearings and avoid internal abrasion. The oil-proof sealing structure adopts contact rubber oil seals, which can effectively prevent the internal lubricating grease of deep groove ball bearings from overflowing and volatilizing, ensuring long-term lubrication effect.

In the universal bearing model coding standard, single-row deep groove ball bearings adopt the type code 6, while double-row deep groove ball bearings correspond to the type code 4. Benefiting from their simple integral structure, convenient installation and stable working performance, deep groove ball bearings are the most mass-produced and widely applied bearing products in the industrial field.
