Angular Contact Ball Bearings

1. Sizes:Inner Diameter: 150-1250mm
Outer Diameter: 190-1750mm, Weight: 1.32-1600kg
2. Structures: Separable, Nonseparable
3. Type: 70000,6000
4. Feature:The single row angular contact bearings can support the axial load in one specific direction. Its axial loading capacity depends on the contact angle α. The bigger the contact angle is, the higher its axial bearing capacity is. The typical contact angle is 15°, 25°, and 40°.
5. Cage:Metal solid cages are mainly used in single row angular contact ball bearings. Phenolic cloth laminated tube solid cages are usually used for high speed applications, and the maximum temperature is 120°C.
6. Material: GCr15/GCr15SiMn/G20Cr2Ni4A
