Angular contact ball bearings are classified into single row angular contact ball bearings, double row angular contact ball bearings, and four-point contact ball bearings. Single row angular contact ball bearings can withstand both radial and axial loads, as well as pure axial loads, with high limit speeds. The ability to withstand axial loads is determined by the size of the contact angle. The larger the contact angle, the greater the axial load to withstand, and the contact angle is divided into 15° 25° 40°. When subjected to radial loads, additional axial forces are generated, so the corresponding reverse axial loads must be applied and should generally be used in pairs. When it is used for installation, it is divided into back-to-back installation, face-to-face installation and serial installation. Double row angular contact ball bearings can withstand large radial load, axial two-way combined load and moment load, and contact angle of 30°. Mainly used in parts that limit the axial displacement of the shaft or housing. Double row angular contact ball bearings are divided into two types: outer ring two inner ring type and two outer ring type - inner ring type. The four-point contact ball bearing is a split type bearing, which is divided into two double outer rings - one inner ring type and two half inner ring one outer ring type. The contact angle is 35o. When there is no internal load and pure radial load, the steel ball and the ferrule channel are in four-point contact, and the radial load capacity is large. Under the pure axial load, the steel ball and the ferrule are two points. contact. This type of bearing can withstand radial loads and any axial load or axial and axial combined load, can also withstand two-way axial load, and has the function of single row and double row angular contact ball bearings. The limit speed is higher. The bearings are used in machine tool spindles, rolling mills, air compressors, printing machinery and other industries. |
