Comprehensive analysis of angular contact ball bearings

Angular contact ball bearings, which is commonly referred to as angular contact ball bearings, which allow the operating speed and deep groove ball bearings are similar, but support more rigid than the deep groove ball bearings, mainly because of the bearing can be loaded more of the ball, the radial load carrying capacity than ordinary ball angular contact bearing large, but also to withstand large axial load or bear pure axial load. These bearings are generally used in pairs for small span rigid support shaft or double precision spindle, can improve the rigidity of the bearing system.
Structural features of angular contact ball bearings Bearing this structure can withstand the radial and axial loads in one direction. Ball with inner, outer ring 15 °, contact angle 25 °, 30 ° or 40 ° of. The contact angle, the greater the axial load carrying capacity. Under normal circumstances, the two single row angular contact ball bearings opposed, adjusted internal clearance to use.
The two radial bearings, combined bearings pairs called pairs of double bearings. Often, by the same pairs of double-bearing angular contact ball bearings or the same combination of tapered roller bearings.
Double pairs of species, there is a positive paired with outer front double, double pairs parallel with the back of the back pairs of double, and in the same direction.
df and db-shaped form pairs of double bearing, can bear radial load and axial load in two directions, dt shape the direction of the axial load for a big occasion.
Double row angular contact ball bearings contact ball bearing outer ring on the back of two separate angles coincide, the inner and outer rings are each integrated structure. Therefore, the import of this structure bearing, thrust load capacity having two directions.

11 ball gap double row angular contact ball bearings 12, No ball gap double row angular contact ball bearings 13, one side with a double row angular contact ball bearings 14 dust cover, dust cover both sides with double 15 row angular contact ball bearings, double row angular contact ball bearings with a ring 16 side, the main purpose row angular contact ball both sides with a double row angular contact ball bearing ring angular contact ball bearings slewing ring bearing: machine tool spindles, high-frequency motors, gas turbines, centrifuges, small car front wheel, the differential pinion shaft.
Double row angular contact ball bearings: pump, blower, air compressor, various types of transmission, fuel injection pump, printing machinery.
