1 single row angular contact ball bearings, single row angular contact ball bearings have the following several kinds of forms:
(1) the separation angle contact ball bearing
The bearing code for S70000, its outer ring raceway edge without locking, can with the inner ring, retainer, tennis component separation, which can be mounted separately. This kind of multi micro bearing diameter less than 10mm, used for gyroscope, micro motor on dynamic balance, vibration, noise, stability have higher requirements in device.
(2) the non separation type angular contact ball bearing
This kind of bearing ring raceway is locked, so the two rings cannot be separated. According to the contact angle is divided into three types:
The contact angle α =40 °, applicable to bear large axial load;
The contact angle α =25 °, used for precision spindle bearing;
The contact angle α =15 °, used for large size precision bearings.
(3) angular contact ball bearings are configured
Angular contact ball bearing in pairs configured to bear radial load and axial load applications, the axial load can be pure radial load bearing and any direction. Such bearings by the manufacturer according to the requirements of a certain degree of pre load, matching pairs portfolio, available to users. When the bearing is installed in the fastening machine, the complete elimination of the bearings in the clearance, and make the ball ring and the key link in the pre state, thus improving the composition of bearing steel.
Angular contact ball bearings are arranged in pair with three different configurations of type:
The back-to-back configuration, post code named DB (such as 70000/DB), steel of this configuration can withstand overturning moment, performance good, two-way bearings can withstand axial load;
