Both radial and axial loads. In high speed work. Larger the contact angle, the higher the axial load capacity. High-precision and high-speed bearings usually take the contact angle of 15 degrees. In the axial force, the contact angle will increase.
Single row angular contact ball bearings can withstand axial load in one direction, the radial load, will cause additional axial force. And the only limit shaft or housing in a direction of axial displacement. Angular contact ball bearing contact angle of 40 degrees, so you can bear large axial load. Angular contact ball bearing non-separation type design, inner and outer rings on both sides of the shoulder uneven. In order to improve the bearing load capacity, which would lower side of the shoulder machined, so that the ball bearings can be put more.
Double row angular contact ball bearings can withstand greater radial load mainly radial and axial joint load and moment load, limiting both the axis of the axial displacement. Main shaft and the housing for limiting the axial displacement member bidirectional
Double row angular contact ball bearings, the outer ring is limited between the tiltable, allowing the tilt angle depends on the bearing internal clearance, bearing size, internal design and acting on the bearing force and torque, while the maximum permissible tilt angle should guarantee bearing will not generate excessive additional stress. If the bearing inner and outer angle of inclination between will affect bearing life, also causing precision bearings running down, running noise increases. Double row angular contact ball bearings generally use nylon cage or solid brass cage. Double row angular contact ball bearing installation should pay attention, although bearings can withstand axial load, but if there is one side of the gap when the ball should be careful not to let the main axial load through the notched side of the gutter. Note that the bearing should be used without the ball gap to bear the main load side of the raceway.
Pairs of double ball bearings
If paired mounting, making a pair of bearing outer ring is relatively wide side face of wide and narrow side facing the narrow end. This can avoid additional axial force, but also in both directions so that the shaft or housing to limit axial clearance range.
Its inner and outer ring raceways in the horizontal axis relative displacement, so it can bear radial load and axial load - combined load (single row angular contact ball bearings can withstand axial load in one direction, so often used in pairs).
Retainers are made of brass, synthetic resins, etc., according to individual bearing features and application conditions.
More angular contact ball bearings are manufactured abroad, bearing manufacturers, domestic imports of equipment used in such large angular contact ball bearings 3204RS, etc.

Feature
1. Universally matchable bearings
Universally matchable bearings are specially processed, when the bearing is installed close to each other, any combination can achieve the established internal clearance or preload, and the average load distribution, without the use of shims or similar devices.
Pairing bearing applications: When a single bearing load carrying capacity is insufficient (associated with channeling configuration) or when to bear the combined load or effect in both directions of the axial load (with back to back or face to face configuration).
2. The basic design of the bearing (not as a general with the group), is configured for a single bearing
Basic design of single row angular contact ball bearings are mainly used in each location is only one bearing configuration. Its width and the amount of outstanding ordinary level tolerances. Therefore not suitable for the two single row angular contact ball bearings close to the installation.
