High precision double row, single row, four point Angular Contact Ball Bearing
?

Like other bearings, angular contact?[ball bearings]?are also have lots of structures, single row angular direction, While double row angular contact ball bearings in DB or DF combination and four-point contact ball bearings can accommodate radial load and axial load in two directions. Angular contact?[ball bearings]?suit high-speed rotation and high-precision rotation. These bearings are mainly used in the fields like machine tool spindles, high frequency motors, oil pumps, air compressors, printing machines, etc. For?[four-point contact ball bearings?]are mostly used in the roller-boxes of rolling mills to carry axial load.

Feature of Angular contact ball bearings:

??? When the single-row angular contact ball bearing is carrying the radial load, they will be a component of force in the axial direction. Therefore it is suggested that two of there bearings be applied in back-to-back or face-to-face arrangements. 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.

?

Applications:

??? These bearings are mainly applied in the machine tool spindles, high-frequency motors, gas turbines, oil pumps, air compressors, printing machines and other installations.
