What is the angular contact ball bearing

Angular contact ball bearings can withstand a direction of axial force and radial force. Rolling element bearing point up and down two attachment, there is a certain Angle and the radial direction. This kind of bearings for angular contact bearings. Angular contact ball bearing what belongs to bearing 1, 【 Angular contact bearing. Belong to the Rolling bearing 】 The 【 Ball bearing 】 2, as the Angular contact bearing. Can bear radial force and axial force, its installation is installed in pairs more, form a back to back, face to face form, 3,' Angular contact bearing. Integral, and can be separated type two kinds, in the installation, typically offer certain axial force, to remove the bearing clearance, bearing, therefore, generally do not give the Clearance. Angular contact ball bearings, self-aligning ball bearing what is the difference between angular contact ball bearings can bear radial load and axial load at the same time. Can work under high speed. The larger the contact Angle, the higher the axial bearing capacity. Because of its outer ring raceway can have relative displacement in the horizontal axis, so can bear radial load and axial load at the same time - — Joint load ( Single row angular contact ball bearings can only carry axial load of single direction, therefore is generally installed in pairs) is often used to 。 Self-aligning ball bearing are angled bearings because of their spherical, with self-aligning performance, thus can be automatically adjusted because of the shaft or shell buckling or axis deviation caused by different heart cone bearing can be easily installed on the shaft by using fasteners stamping steel wheel and steel ball inside the cage can foreign wheel free tilt, therefore, a certain degree of assembly error ( Don't treat) Or axial radial curve can be automatically adjusted, without damage to the bearings. Angular contact ball bearing characteristics and purposes of the usage of the angular contact ball bearings, angular contact ball bearing limit rotational speed is higher, can bear radial load and axial load at the same time, also can withstand pure axial load, its axial load capacity is determined by contact Angle, and with the contact Angle increases. Single row angular contact ball bearings can only carry axial load in one direction, when bear radial load, will cause the additional axial force, must be applied to the corresponding reverse load, therefore, this kind of bearings are generally used in pairs. Double row angular contact ball bearings can withstand the bigger radial direction load primarily radial, axial two-way joint load and torque load, it can limit shaft or shell two-way axial displacement, the contact Angle of 30 degrees. Installation Angle contact ball bearing in pairs can afford to two-way joint mainly consisting of radial load, axial load, also can withstand pure radial load. Serial configuration can only carry axial load in single direction, the other two configurations can carry axial load in either direction. This type of bearings in general by submitting users, manufacturers matching combination pairs after installation preloading interference, ring and ball in the axial preload charge state, thus increasing the support stiffness and the whole bearing as a single rotation accuracy.
