Angular contact ball bearings have a high limit speed and can bear radial loads and axial loads at the same time, as well as pure axial loads.
Inner diameter range: 8~360mm.
Product features: ultra-high speed, high rigidity, suitable for grease lubrication, oil-gas lubrication or jet lubrication.
Application areas: Widely used in machine tools, steel & metal, injection molding machine, mining and construction, semiconductor, cement, motorcycles, gearboxes, industrial motors, pump & compressors, wind turbine.
The company's precision angular contact ball bearings are divided into four series: high-speed angular contact bearings (standard series), ultra-high-speed angular contact ball bearings, high-speed sealed angular contact ball bearings and high-speed spindle bearings. The precision angular contact ball bearings for spindles are available in four size series: 718, 719, 70 and 72.
The contact angle of angular contact ball bearings is divided into 15° (code C) and 25° (code AC). The larger the contact angle, the greater the axial load capacity, but the lower the bearing's limit speed. Therefore, the main shaft support with high speed and small axial load should use a bearing with a contact angle of 15°. Conversely, an angular contact ball bearing with a contact angle of 25° should be used.
Single-row angular contact ball bearings often need to be installed in conjunction with other bearings that bear axial loads in the opposite direction. In other words, angular contact ball bearings are usually used in duplex, triplex, quadruple, or even quintuple combinations.
The inner and outer rings and rolling elements of rolling bearings used under general working conditions are made of high-carbon chromium bearing steel. The company also provides widely used hybrid ceramic angular contact ball bearings for high-speed precision machine tool spindles and other high-speed precision mechanical spindles. That is, the inner and outer rings of the bearings are made of high-quality bearing steel materials, while the rolling elements are made of silicon nitride ceramics. Compared with standard steel angular contact ball bearings of the same structure and size, hybrid ceramic angular contact ball bearings have the advantages of good high-speed performance, high rigidity, low friction heat generation and long life.
