  • 7002A DB-Angular contact ball bearings for precision machinery
PREV：7002A DF-Angular contact ball bearings for precision machinery NEXT：7002A DTA-Angular contact ball bearings for precision machinery
Product description Technical parameter
Precision angular contact ball bearing, belongs to the deep groove ball bearing deformation structure, suitable for all kinds of precision machinery selection, this series of bearings can bear radial load and axial load at the same time, can work at a higher speed. The larger the contact angle, the higher the axial load carrying capacity. According to the axial load size, contact angle is mainly divided into C-15 degrees, AC-25 degrees, A-30 degrees, B-40 degrees type structure, small friction coefficient, high limit speed, high manufacturing accuracy, can provide high-speed ceramic ball series bearings and sealed series bearings, cage mainly organic processing window brass cage, steel plate stamping cage, glass fiber reinforced nylon cage (nylon), and phenolic Laminated cloth tube cage (rubber wood), also can provide universal pair and any pair combination bearings. Mainly used in: machine tool spindles, high frequency motors, gas turbines, centrifugal separators, small car front wheels, differential pinion shafts, booster pumps, drilling platforms, food machinery, indexing heads, welding machines, low-noise cooling towers, electromechanical equipment, coating equipment, machine tool groove plates, arc welding machines, water pumps, modules, and support seats.

Can automotive  angular contact ball bearings handle both radial and axial loads in automotive applications?
automotive angular contact ball bearings are designed to handle both radial and axial loads simultaneously. These bearings are engineered to provide efficient support for the complex loading conditions typically encountered in automotive applications.
Here's how automotive angular contact ball bearings accommodate both radial and axial loads:
Angular Contact Design:Automotive angular contact ball bearings are designed with an angle between the inner and outer raceways. This angle is known as the contact angle.
The angular contact design allows these bearings to carry both radial and axial loads in varying proportions.
Load Distribution:The arrangement of the races and balls in angular contact ball bearings facilitates an even distribution of loads between the radial and axial directions.
Depending on the specific design, these bearings can effectively handle thrust (axial) loads in addition to the radial loads.
Different Contact Angles:Manufacturers offer angular contact ball bearings with different contact angles, such as 15 degrees, 25 degrees, or 40 degrees.
Bearings with larger contact angles are better suited for handling higher axial loads.
Tandem and Back-to-Back Configurations:In some automotive applications, angular contact ball bearings may be arranged in tandem or back-to-back configurations to optimize load-carrying capacity.
These configurations are used to enhance the ability of the bearings to handle axial loads.
Preload Adjustment:Preloading is a technique used to eliminate internal clearances in the bearing, improving its rigidity and ability to handle axial loads.
Some automotive angular contact ball bearings may have provisions for adjusting preload to optimize performance under specific loading conditions.
Sealed or Shielded Versions:Automotive angular contact ball bearings often come in sealed or shielded versions to protect against contamination, ensuring reliable performance over the bearing's lifespan.
These features make automotive angular contact ball bearings versatile for use in various automotive components, such as wheel hubs, transmissions, differentials, and other applications where both radial and axial loads are present. The ability to handle combined loads makes these bearings crucial for optimizing the performance and reliability of automotive systems.
