TWATURE:
1)When the single-row angular contact ball bearing is carrying the radial load, there will be a component of force in the axial direction. Therefore it is suggested that two of these bearings be applied in back-to-back or face-to-face arrangement.
2)These bearings have contact angles between the rings and balls. The standard angles are 15°,25°,and 40°.The greater the angle, the higher the rotating speed.
3)Single row bearings can carry radial load and axial load in one direction. Double-row angular contact ball bearings have two designs of one outer ring and two inner rings and one outer ring and one inner ring. For the design with one outer ring and two inner rings, the axial clearance is easy to control during machining.
4)Angular contact ball bearings are applied for high speed and high precision rotating conditions
APPLICATION:
These bearings are mainly applied in the machine tool spindles high-frequency motors, gas turbines, oil pumps air compressors, printing machines and other installations.
We also can produce according to client’s sample and drawing, OEM is welcome. The more detail pls check the catalogue or contact with us.
