A single angle contact ball bearing have the following kinds structure form:

(1) separated type angle contact ball bearing

This bearing code S70000, its outer ring rolling heats not locked mouth, and inner circle, retainer, outline the ball component separation, and therefore can be installed separately. This kind of more for less than 10 mm diameter of miniature bearing, used for gyro rotor, micro motors on the dynamic balance, noise, vibration, stability, and higher demand in the device.

(2) the separation type angle contact ball bearing

This type of bearing rings channel have a lock on the mouth, so the two front-runners can't separate. According to the contact Angle is divided into three types:

(1) contact Angle α = 40 °, apply to bear the larger axial load;

(2) the contact Angle α = 25 °, more for precision spindle bearing;

(3) contact Angle α = 15 °, more for larger size precision bearings.

(3) in the configuration of the angle contact ball bearing

Pairs the configuration of the angle contact ball bearing used in both radial load and axial load occasions, it also can be subject to pure radial load and any direction of the axial load. These bearings by factories in a certain type of the load demand, optional combination pairing, to give users use. When bearing installed in machine after fastening, totally eliminates the bearing clearance, and make rings and outline the ball in a preloaded state, thus improve the combination of bearing rigidity.

Pairs the configuration of the Angle contact ball bearing has three different configuration type:

(1) back-to-back configuration, or code DB (such as 70000 / DB), the configuration of the good rigidity, bear overturning the performance is good, bearing can be subject to bi-directional load;

(2) the face-to-face configuration, or code for DF (such as 70000 / DF), this configuration rigidity and bear the ability of overturning as DB configuration form, the bearing can be subject to bi-directional load;

(3) series configuration, or code DT (such as 70000 / DT), this is also available in the same supporting place three or more bearing series, but can only take a one-way axial load. Usually, in order to balance and limit the axial displacement of the shaft, and the other in supporting installation can withstand the other direction axial load bearing.

In addition, still have a kind of available for any pairing of a single Angle contact ball bearing. This bearing through special processing, can two back-to-back, two face-to-face or two series, either way combination, the matchmaking combination of the axial clearance can choose according to need, or code CA said smaller axial clearance, CB said axial gap moderate, CC said larger axial clearance.

 
Universal pairing of bearing, also can press use requirement is configured to have made the bearings, and later for code GA, GB, GC said. GA said after the smaller matching preloaded surplus; GB said after the matching interference medium; GC said after the larger matching preloaded tracker.
