Super precision of angular contact ball bearing 3216 zz

Angular contact ball bearings are particularly suitable for carrying combined (axial and radial) loads. Sometimes, they also can carry pure axial load and operate in higher speed. Under radial load, axial component force will be produced which must be counteracted. So the bearings are normally adjustable against a second bearing.        
Single row angular contact ball bearings can carry axial load acting in one direction only. In many applications, angular contact ball bearings in pairs or multi-arrangement should be used. The axial load carrying capacity of angular contact ball bearings increases with the increase of contact angle.
P4 Angular Contact Ball Bearing Features
Individual bearings of this type are capable of taking radial loads and also axial loads in one direction. Contact angles of 15°, 25°, 30°, and 40° are available. The larger the contact angle, the higher the axial load capacity. For high-speed operation, however, the smaller contact angles are preferred. Usually, two bearings are used in duplex pairs, and the clearance between them must be adjusted properly.
Pressed steel cages are commonly used, however, for high precision bearings with a contact angle less than 30°, polyamide resin cages are often used.
Applications
P4 Angular Contact Ball Bearing These bearings are mainly applied in the machine tool spindles, high-frequency motors, gas turbines, oil pumps, air compressors, printing machines and other installations.

P4 Angular Contact Ball Bearing Double row angular contact ball bearings can withstand larger radial load and axial joint load and torque load, limit the axial displacement of the two aspects. Mainly used for limiting the axial displacement of the shaft and the shell.
Double row angular contact ball bearing inner and outer ring of the tilt between the limited, allowing the tilt angle depends on the internal clearance of the bearing, bearing size, internal design and role in bearing the force and torque, and the maximum allowable inclination angle should ensure that the bearing will not produce high additional stress.
