Deep groove ball bearing consists of an outer ring, an inner ring, a set of steel balls and a set of cages. It mainly bears pure radial loads, but also can bear joint loads. When it is subjected to pure radial load, its contact Angle is zero. When it has a larger radial game, that is, it has angular contact bearing performance, which can withstand a larger axial load. Deep groove ball bearing has small friction coefficient and high limit speed, so it has more advantages than thrust bearing when axial load is rotating at high speed. But because its aligning performance is limited, the concentricity of bearing installation should be high, otherwise it will affect the balance of its operation, increase the bearing stress, and thus shorten the working life. Deep groove ball bearing simple structure, compared with other easy to achieve high precision, so can be mass production. In addition to the conventional models, it also has a variety of structural variations, such as deep groove ball bearing with dust cover, deep groove ball bearing with rubber ring and deep groove ball bearing with a stop groove and so on.       Q:What Is The General Fit Between The Inner And Outer Ring Of Bearings And The Shaft. A:It is generally an interference fit. According to the direction and nature of the load acting on the bearing and which side of the inner and outer ring rotation, the load borne by each ring can be divided into rotating load, static load or non-directional load. The ferring bearing rotating load and non-directional load should be static fit (interference fit), and the ferring bearing static load can be transitional fit or dynamic fit (gap fit). When bearing load is large or bearing vibration and impact load, its interference must increase. When using hollow shaft, thin-wall bearing box or light alloy, plastic bearing box, also must increase the amount of interference. When high rotation is required, high-precision bearings should be used, and the dimensional accuracy of shaft and bearing box should be improved to avoid excessive interference. If the interference is too large, the geometry accuracy of the shaft or bearing box may affect the geometry of the bearing ring, thus impairing the rotation accuracy of the bearing. Non-separation type bearing (such as deep groove ball bearing) inner and outer ring are static fit, bearing installation, disassembly is extremely inconvenient, it is best to use a dynamic fit of one side of the inner and outer ring.       Why Choose Us 1.High speed, High Precision, Low Noise, Long Service Life 2.Widely used 3.Large Inventories 4.High Quality and Competitive Prices 5.Various Brands 6.OEM is supported
