High Precision Double row angular contact ball bearings

Angular contact ball bearings have raceways on the inner and outer rings, and the inner and outer rings can be displaced relative to each other along the axial direction of the bearing. These bearings are particularly suitable for withstanding composite loads, ie loads acting simultaneously in both radial and axial directions. The axial load bearing capacity of the angular contact ball bearing increases as the contact angle α increases. The contact angle is the angle between the line connecting the contact point of the ball and the raceway in the radial plane and the vertical line of the bearing axis.

Angular contact ball bearing accuracy class includes dimensional tolerance and rotation accuracy. From low to high accuracy is expressed as P0(ordinary), P6(P6X), P5, P4, P2, in addition, P3, P7, P9 are also used in European and American brands to indicate accuracy levels, P3 is equivalent to level P6 of ISO and JS standards, P7 is equivalent to level P4, and P9 is equivalent to level P2.

The characteristic of angular contact bearing is that it can bear both radial load and single axial load. The larger the contact Angle, the larger the axial load, the smaller the contact Angle, the smaller the axial load. Conversely, the smaller the contact Angle, the greater the ability to bear radial loads, and the more suitable for high-speed applications. According to different working conditions, it can be combined in a variety of ways to obtain different radial and axial load capacity, and meet the requirements of high speed and diameter, and high axial stiffness.

Product features of angular contact ball bearing:

High-quality bearing materials: 

WGHB adopts ultra-clean steel, high purity high-carbon chromium bearing steel GCr15 from a well-known domestic manufacturer, which can extend the life of the bearing by 80%.

High quality bearing rolling elements: 

The bearing balls provided by WGHB have good product performance to ensure the optimal bearing configuration and smooth operation at high speed and quiet. WGHB has a complete process production line, from powder ultrasonic pre-dispersion, mixture mixing, spray drying granulation, near-net-size molding, cold isostatic pressing, GPS-HIP combined sintering process, high-precision grinding and processing, total quality inspection to packaging. 

More suitable bearing cage: 

WGHB mostly adopts bakelite cage, which can more effectively reduce the friction between metal and bearing balls and extend the life of the bearing. WGHB can also choose more suitable bearing cage materials according to customer requirements and bearing applications.

Advanced lubrication technology: 

WGHB uses high performance grease and advanced lubrication technology to extend bearing life and improve bearing performance.

Ultra finished raceways: 

WGHB uses special honing to minimize noise, improve lubricant dispersion and increase bearing life.

Contact angle: 

WGHB ultra high speed precision bearings usually use 15°and 25° contact angles.

Accuracy grade:

WGHB can offer the high precision angular contact ball bearings with P2, P4A, P4 grade.
