/ Single row angular contact ball bearings

Precision Angular Contact Ball Bearings

1.Product Introduction: The raceways are processed by ultra-precision grinding, with radial runout ≤ 0.002mm, suitable for high-speed and high-precision transmission, and are mostly used in the core spindles of high-end equipment.
2.Structure Type: Inner ring / outer ring (ultra-precision ground angular contact raceway, Ra ≤ 0.02μm) + precision steel balls + aerospace aluminum alloy or brass cage, and some are equipped with positioning steps.
3.Size Range: Inner diameter: 20 - 300mm, outer diameter: 47 - 500mm, width: 14 - 100mm.
4.Material: Inner ring / outer ring: GCr15 (ultra-precision forged), rolling elements (steel balls): GCr15 (ultra-precision ground), cage: aerospace aluminum alloy (for high-speed) / brass (for precision).
5.Accuracy: Conventional P0 grade, precision models are of P6/P5/P4 grades.
6.Application Fields: Spindles of CNC lathes, machining centers, aerospace equipment, precision testing instruments, semiconductor manufacturing equipment.
7.Key Inspection Items: Radial runout (≤ 0.002mm), running noise (≤ 40dB), accuracy of contact angle, surface roughness of the raceway.
