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