Angular contact ball bearings Jixiang heart Thrust Ball Bearings , as can be loaded more of the ball, the radial load carrying capacity greater than the ordinary ball bearings , can withstand large axial load or bear the pure axial load, which allows work speed  and bearing deep groove ball bearing similarities more rigid , but requires precise installation for misalignment error is very sensitive, it is generally not used alone to bear radial load , radial load while at the same time will bring additional axes to the load . This variant bearing many varieties of applications is very broad, often made with 15 °, 25 ° and 40 ° contact angle of three kinds of series, the greater the contact angle , the higher the axial load capacity , but should be used at high speed small contact angle is appropriate.
Most of these bearings Stainless steel slewing bearing in pairs for a small span rigid double precision spindle bearing axis or , when used to carefully adjust the clearance, change the bearing inner and outer axial distance , you can adjust the bearing internal clearance , while the several sets of bearings installed in parallel and give some preloaded amount , can improve the rigidity of the bearing system .
This type of single bearings can withstand axial load in one direction , while others need to be configured in order to offset the additional axial bearing force when it is made on the installation of additional axial force which cancel each other out , and can withstand tapered bearing up two forces axial load , and has two strong axial direction limit ability to be installed in pairs generally use two sets of bearing outer race wide face with its relative ( back to back ) or a relatively narrow end ( face to face ) two installation forms , where rigid bearing system mounted back to back best . For ease of installation in pairs or groups , some bearing factory supply in pairs, a group of three and four sets of a group such as bearings, bearing the same batch so that the supply of processing consistency, use bear the load more evenly , additional axial forces cancel each other more thoroughly .
This type of bearing and non- separable non-ionic type two, the separation of bearings for restricted installation conditions , requirements from the entire outer or inner ring bearings were installed in order to remove the case , since the separation of angular contact ball bearings are widely used in magnetic motor , it is also known as magneto bearings. This type of bearing on the inner ring in the locking variety, can be adapted to higher speeds .
