The single row angular contact ball bearings structural forms.

1,026 Published by Jan 22,2019

The single row angular contact ball bearings are coded S70000, and the outer ring raceway has no locking edge and can be separated from the inner ring, the cage and the ball assembly, so that it can be installed separately. Most of these miniature bearings with an inner diameter of less than 10 mm are used in devices with high requirements for dynamic balance, noise, vibration and stability, such as gyro rotors and micromotors.

The ferrule channel of this type of single row angular contact ball bearings has a locking port, so the two rings cannot be separated. According to the contact angle, there are three types:
1 single row angular contact ball bearings with contact angle α=40°, suitable for withstanding large axial loads;
2 single row angular contact ball bearings with contact angle α=25°, mostly used for precision spindle bearings;
3 Single row angular contact ball bearings with contact angle α=15°, mostly used for larger size precision bearings.

Single row angular contact ball bearings in pairs are designed to withstand both radial and axial loads, as well as pure radial loads and axial loads in either direction. The single row angular contact ball bearings are selected by the manufacturer according to a certain preload requirement, and are provided in pairs for use by the user. When the bearing is mounted on the machine, the clearance in the bearing is completely eliminated, and the ferrule and the ball are pre-tensioned, thereby improving the rigidity of the combined bearing.

The single row angular contact ball bearings in pairs are available in three different configurations:
1 Back-to-back configuration, the rear code is DB (such as 70000/DB), this configuration is better in steel, and it has good performance under the overturning moment, and the bearing can bear the bidirectional axial load;
2 face-to-face configuration, the rear code is DF (such as 70,000 / DF), the rigidity of this configuration and the ability to withstand the overturning moment is not as good as the DB configuration, single row angular contact ball bearings can withstand two-way axial load;
3 series configuration, rear coded DT (such as 70000/DT), this configuration can also be connected in series with three or more single row angular contact ball bearings, but can only bear axial load in one direction. Usually, in order to balance and limit the axial displacement of the shaft, the other bearing needs to be fitted with a bearing that can bear the axial load in the other direction.

In addition, there is a single row angular contact ball bearings that can be paired. The single row angular contact ball bearings are specially processed and can be combined in any combination of two back-to-back, two face-to-face or two series. The axial clearance of the paired combination can be selected according to requirements. The rear code CA indicates that the axial clearance is small. , CB indicates that the axial clearance is moderate, and CC indicates that the axial clearance is large.
The universal matched bearing can also be configured as a bearing with pre-interference according to the requirements of use, and will be indicated by the codes GA, GB and GC. GA indicates a small pre-interference after pairing; GB indicates a medium pre-interference after pairing; GC indicates a larger pre-interference after pairing.
