Angular contact ball bearings 3216ATN
Angular contact ball bearings can support radial load and axial load, you can also afford pure axial load, the higher speed limit. The axial load bearing capacity of the decision by the contact angle, contact angle large, the ability to withstand high axial loads. Contact angle α is defined as the radial plane to connect the contact ball and roller bearing axle line and a vertical line with the angle between.
Single row angular contact ball bearings have the following structure
(1)Separate angular contact ball bearings
This bearing the code name for the S70000, the outer ring raceway side no locking, with inner ring, cage, Gang ball component separation, which can be installed separately. These are mostly less than 10mm diameter miniature bearings, for gyroscope rotor, micro motors on the dynamic balance, noise, vibration, stability of the devices have higher requirements.
(2)Non-separation-type angular contact ball bearings
These bearings are locking ring channel, so can not separate the two sets of circles. Divided into three types according to the contact angle
a.Contact angleα=40°,Apply to bear large axial load
b.Contact angleαα=25°,Are used for precision spindle bearings
c.Contact angleαα=15°,Multi-precision bearings for the larger size.
(3)Pair of angular contact ball bearing configuration
Pair of angular contact ball bearing configuration used to support radial load and axial load of occasions, also can take pure radial load and axial load in either direction. Such bearings from the manufacturer in accordance with certain pre-load requirements, matching pairs combination available to users. When the bearings installed in the machine fastening, the complete elimination of the bearings in the clearance, and to preload ring and the key link in the state of the ball, thus increasing the bearings of the steel.
Single row angular contact ball bearings with radial load mainly radial and axial joint load, but also pure radial load to bear, in addition to tandem configuration, the other two configurations can withstand axial load in either direction. In the radial load, will cause additional axial force. Therefore, pairs normally takes to do any matching of bearing, the bearing installed in pairs according to the combination of the outer ring is divided into different sections: back to back configuration, face to face configuration, series configuration (also known as: O-type configuration, X-type configuration, T-configuration) of three types.
a.Back to back configuration, post code for the DB (such as 70000/DB), back to back pair of bearing the load line to separate the bearing axis. Affordable acting on the axial load in two directions, each direction of the load can only be a bearing. Back to back installation of the bearing to provide a relatively high stiffness bearing configuration, and can withstand overturning moment.
b.Face to face configuration, post code-named DF (such as 70000/DF), face to face match the load bearing line to the bearing axis converge. Affordable acting on the axial load in two directions, each direction of the load can only be a bearing. This configuration is not as good as back to back pair of rigid high and not suitable to withstand overturning moment. This configuration of the rigidity and the ability to withstand overturning moment as DB configurations, two-way bearings can withstand axial load.
c.Series configuration, post code-named DT (such as 70000/DT), series configuration, the load line parallel, radial and axial load from the bearings evenly shared. However, the bearing can only bear group acting on a direction axial load. If the axial load in the opposite direction, or if there is complex load, you must add a series matching the relative adjustment of the third bearing bearings. This configuration also supports office in the same series of three or more bearings, but can only afford a one-way axial load. Typically, in order to balance and limit the axial displacement, and the other supporting Department should be installed to withstand the axial load bearing another direction.
