F&F angular contact ball bearing can support radial load and axial load, it also can be subject to pure axial load, limit rotational speed is higher. The F&F axial load bearing capacity of the decision by the contact angular, the contact angular is big, bear axial load of high ability. Contact angular is defined as the intimacy competency scale, radial plane connected ball and groove contacts with a line with bearing shaft angular between the vertical lines.

F&F single angular contact ball bearing have the following kinds structure form:

(1) F&F separation type angular contact ball bearing

This bearing code S70000, its outer ring rolling heats not locked mouth, can and inner circle, maintains , 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 angular 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.

F&F single Angle contact ball bearing to the radial direction load primarily diameter, the axial union load, can also be subject to pure radial load, in addition to the series configuration, the other two are under any configuration of the direction of the axial load. In the radial load, will cause additional axial force. So generally need to use in pairs, do any pairing of bearing combination, and pair of bearing according to the outer ring installation end of the different combination is divided into: back-to-back configuration, face-to-face configuration, series configuration (also called: type O configuration, X configuration, T configuration) three types:

F&F back-to-back configuration

Type O configuration

F&F face-to-face configuration

X configuration

F&F series configuration

T configuration

(1) back-to-back configuration, F&F rear code DB (such as 70000 / DB), back-to-back pairing of bearing load bearing shaft line to separate. May withstand the role in two direction of axial load, but each direction of load only by a bearing. The installation of bearing rigidity back-to-back provide relatively high bearing configuration, and can withstand overturning.

(2) the face-to-face configuration, or code for DF (such as 70000 / DF), face to face the load bearing the pairing of line up to bearing shaft. May withstand the role in two direction of axial load, but each direction of load only by a bearing. This configuration as back-to-back pairing of rigidity is high, but not so good for bear overturning. 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), series configuration, load line parallel, radial and axial load bearing Shared by uniform. But, bearing group can only take effect in a direction of axial load. If axial load function in the opposite direction, or if there is a composite load, you have to add a relative series matching bearing adjustment of the third bearing. This configuration 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.

F&F 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.
