Angular Contact Ball Bearings Single Row

1.Product Introduction: The basic version of angular contact ball bearings, with a single-row steel ball and single contact angle design, mainly designed to bear unidirectional combined loads. It needs to be paired with other bearings to balance the axial force.
2.Structure Type: Inner ring (with guide groove) + outer ring (with single angular contact raceway) + single-row steel balls + brass or stamped steel cage, featuring a compact structure and convenient installation.
3.Size Range: Inner diameter: 15 - 400mm, outer diameter: 40 - 600mm, width: 11 - 150mm.
4.Material: Inner ring / outer ring: GCr15/GCR15SIMN, rolling elements (steel balls): GCr15/GCR15SIMN, cage: stamped steel (conventional model) / brass (precision model).
5.Accuracy: Conventional P0 grade, precision models are of P6/P5/P4 grades.
6.Application Fields: Small and medium-sized motors, feed shafts of machine tools, automobile steering systems, precision instruments, water pumps.
7.Key Inspection Items: Contact angle (selectable as 15°, 25°, or 40°), radial clearance (0.003 - 0.008mm), stability of the cage, conformity of steel balls fitting.
