Angular contact ball bearings Spherical roller shaft tapered roller bearings Luoyang Bearing Co., Ltd. Ma Ma Luoyang Bearing Co., Ltd. is a professional manufacturer of needle roller bearing manufacturers. Male plants produce more than 2,000 species. Imperial bearing models. The main products are: Needle roller bearings, needle roller cage assemblies, connecting rod with needle roller cage assemblies, thrust needle roller bearings, needle roller bearings entity rings, bearing roller, roller and needle curves, etc. . Widely used in automobiles, trucks, tractors, motorcycles, scooters, electric tools, textile machinery, machine fishing nets, agricultural machinery, printing machinery, engineering machinery, fitness and entertainment equipment, logistics systems and automatic instrumentation and other fields. Bearing products exported to Europe, Asia and many other countries and regions, deeply domestic and foreign customers. Bearings ("Bearing", the Japanese called "axis by") is fixed and reduce the load coefficient of friction components in mechanical transmission process. You can also say that when the other parts on the shaft movement relative to each other, the process used to reduce the power transmission coefficient of friction and keep the shaft center position fixed parts. Bearing is a kind of modern machinery and equipment vital components. Its main function is to support the mechanical rotary member, the drive device for reducing the mechanical load during the friction coefficient. According to the different nature of friction of moving parts, the bearings can be divided into two types of rolling bearings and plain bearings Four-point contact ball bearings are separable bearings, four point contact ball and rings can bear radial load and axial load in either direction or radial and axial joint load. The axial clearance on both sides of this kind can limit the axial displacement of the bearing shaft or housing in the bearing. When paired installed back to back or face to face, should be provided in the middle of the two outer spacer ring. By grinding mill thickness of the inner and outer rings to control radial clearance (also achieve this objective through two grinding surfaces of the bearing inner ring protruding amount). And there are preloaded during installation, thereby increasing the load capacity, rigidity and precision rotating set of paired bearings. Four-point contact ball bearings compared with the double outer (inner) double row angular contact ball bearings, high precision rotary bearings of the type matching, accurate positioning, but the complexity of the installation of artificial demanding.
