Angular Contact Ball Bearings

1.Product Introduction: With contact angles of 15°, 25°, or 40°, they can bear combined radial and axial loads. The larger the contact angle, the stronger the axial load-bearing capacity. They are suitable for various precision transmission scenarios.
2.Structure Type: Inner ring + outer ring (with angular contact raceway) + single-row steel balls + cage. They can be used in pairs in a back-to-back or face-to-face arrangement.
3.Size Range: Inner diameter: 15 - 500mm, outer diameter: 40 - 800mm, width: 11 - 180mm.
4.Material: Inner ring / outer ring: GCr15/GCR15SIMN, rolling elements (steel balls): GCr15/GCR15SIMN, cage: brass (conventional) / aerospace aluminum alloy (for high-speed models).
5.Accuracy: Conventional P0 grade, precision models are of P6/P5/P4 grades.
6.Application Fields: Machine tool spindles, turbochargers, high-end motors, precision reducers, automobile transmissions.
7.Key Inspection Items: Accuracy of contact angle (deviation ≤ 1°), radial runout (≤ 0.005mm), consistency of pairing clearance, running noise (≤ 45dB).
