● Introduction
SKF spherical roller bearings are produced by SKF. Founded in 1907, SKF is one of the world's largest rolling bearing manufacturers. SK company has more than 80 factories, mainly producing various types of bearings, seals, special steel for bearings, accounting for 20% of the global bearing production, and its business covers 130 countries and regions. As early as 1912, SKF entered China. It has 11 manufacturing plants and a number of service units in China. We maintain good cooperation with SKF and can distribute SKF bearings. SKF spherical Roller Bearings can be self-aligning, the bearing can bear large radial load, and can also bear two-way axial load and its combined load, with large bearing capacity and good anti-vibration and impact resistance.
SKF roller bearings can be applied to industrial equipment, papermaking, prevention and control, mining, metallurgy, construction and other large machinery and equipment, agricultural machinery and other fields.
● Bearing Series
The types of the spherical Roller Bearings include 20000E series, 20000EK series, 20000CC series, 20000CCK series, 20000CC/W33 series, 20000CA/W33 series, 20000CCK/W33 series, 20000CCK30/W33 series, 20000ECCJ/W33 series and 20000ECCK30/W33 series.

● Production Details
◆ Allowance and tolerance for bearing ring turning
The machining allowance and tolerance of the bearing ring are necessary for cutting, which changes with the production conditions. The influencing factors include the structural shape and size of the bearing ring. The size of the ring is large, the structure and shape are complex, and the cold and hot processing is easy to deform. The remaining amount and tolerance should also be increased. The material composition of the ring, the uniformity and tightness of the internal organization. Intrinsic quality of blank manufacturing, stability of annealed structure, existence of residual stress, etc., equipment for turning and grinding processes, performance quality and use adjustment status of tools, clamps and measuring tools, rationality of turning and grinding process design, directly affects the processing quality of the ferrule, thereby affecting the allowance and tolerance: the ferrule handles the deformation amount and the depth of the decarburized layer. The bearing accuracy grade, the final technical requirements of the ferrule, the level of production management, the degree of production standardization and the processing technology of workers level etc.
◆ Cage material
When the bearing is working, especially when it rotates at high speed, the cage has to bear great centrifugal force, shock and vibration, great sliding friction, and generate a lot of heat. Therefore, the material is required to have good thermal conductivity, wear resistance, small friction coefficient, small specific gravity, certain strength, expansion coefficient similar to that of rolling elements, and good processing performance. Bearing cages for special purposes also have special requirements, such as high temperature resistance. At present, the commonly used cage materials are high-quality low carbon steel (08A1, 10, 08), brass, bronze, stainless steel, phenolic tape tube, plastic and so on.
● Bearing Dirt Noise
When the bearing is not clean and the lubricant contains dust, dirt or foreign objects, it will cause non-periodic vibration and noise. Its noise is irregular and not fixed. Especially small and miniature bearings are sensitive to it. Dirt not only damages the rolling surfaces, but also reduces bearing life. To remove dirt, high-purity lubricants can be used, cleaning methods, the cleanliness of bearings and the sealing performance of bearing components can be improved.
