Angular Contact Balling Bearing

Anuglar Contact Ball Bearing with competitive price with lower noise and high quanlity

Characteristics

Angular contact bearings are single row ball bearings but designed in such a way that the central line of the contact between balls and raceways is at an angle. This angle is called a contact angle and as per the manufactured design these vary between 15o, 25o,45o In this type of bearings contact angles between balls and tracks have been swung to an angle between 20o to 40o to the radial plane.

These bearings are capable of carrying higher axial loads than the corresponding deep groove ball bearings, but in one direction only. These bearings are eminently suitable where heavy thrust (axial) loads are encountered at high speeds.

Usually these bearings are mounted in pairs and adjusted axially against

each other so that they may support combination of heavy radial and thrust (axial) loads. If paired mounting, make the end faces of outer rings of two bearings face to face, i.e. wide end face to wide end face (DB type) and narrow end face to narrow end face (DF type).

This bearing is most used in the applications with high rotational speed, high precision and small axial load such as main shaft of motor of airplane,main shaft of machine tool and other main shafts of high speed and precision machinery. It is also used on high frequency motor, gas turbine, oil prump, air compressor, printing machines etc. It is a most widely used bearing in machinery industry.

Types  

RICH can supplies four types of angular contact ball bearing :    Single-row angular contact ball bearing:    7000C, 7000AC, 7000A, 7000B    Paired-mounting angular contact ball bearing:    Face to Face (DB) , Back to Back (DF), Tandem (DT), Triple    Four-point contact ball bearing    QJ0000, QJF0000 

Demension Range

The following dimension data table is about the basic dimensions of ZWA angular contact ball bearings ,    Single-row angular contact ball bearing        Dimension range of bore diameter: 150mm-1180mm        Dimension range of outer diameter: 225mm-1420mm        Dimension range of overall width: 35mm-106mm    Matched pair angular contact ball bearing        Dimension range of bore diameter: 100mm-1320mm        Dimension range of outer diameter: 180mm-1600mm        Dimension range of overall width: 68mm-106mm    Four- point contact ball bearing        Dimension range of bore diameter: 150mm-480mm        Dimension range of outer diameter: 225mm-870mm        Dimension range of overall width: 35mm-170mm

Tolerance

The standard tolerance of Single-row angular contact ball bearing is manufactued by Class P0, but ZWA can also supply the bearings meeting precision Class P6 or higher. For a single-row bearing with contact angle of 15o and 25o used for paired mounting, the precision class meet P5. For a single row bearing with contact angle of 45o used for paired mounting, the precision class meets P6. ZWA also can supply the bearings with precision 4A, 2A or other precision requirements.

Cage

RI CH angular contact ball bearings belong to middle-size and large-size types. So, usually, they use Solid brass cage
