Angular Contact Ball Bearing

1.Product Introduction: With strengthened raceway thickness and larger steel ball size, mainly with a 40° contact angle, the axial load-bearing capacity is significantly improved, suitable for medium and heavy combined load scenarios.
2.Structure Type: Inner ring + outer ring (thick-wall angular contact raceway, quenching depth ≥ 5mm) + large-diameter steel balls + steel cage, with strong impact resistance.
3.Size Range: Inner diameter: 30 - 600mm, outer diameter: 72 - 1000mm, width: 20 - 200mm.
4.Material: Inner ring / outer ring: GCr15/GCR15SIMN, rolling elements (steel balls): GCr15/GCR15SIMN, cage: steel (impact-resistant).
5.Accuracy: Conventional P0 grade, precision models are of P6/P5/P4 grades.
6.Application Fields: Spindles of heavy-duty machine tools, transmission ends of port cranes, mining machinery, large reducers.
7.Key Inspection Items: Hardness of the raceway (HRC60 - 65), axial load-bearing capacity (≥ 80kN), radial runout, integrity of steel balls.
