Angular Contact Ball Bearing (7000-7300 Series)
- Angular contact ball bearings are suitable for applications that require high accuracy and good high-speed performance.
- This type of bearing is designed to carry a combined load.
- 7000-7300 Series.
About Angular Contact Ball Bearing
Single-row angular contact ball bearings and matched pair angular contact angle contact ball bearings.
- Single-row angular contact ball bearings accommodate radial load and axial load in one direction.
- Bearings with a machined cage are suitable for high-speed applications.
- The standard contact angles are 15°, 30°, and 40°.
- They are identified, respectively, by the supplementary codes "C", "A" (omitted), and "B".
- Bearings with a smaller contact angle are more suitable for applications involving high-speed rotation.
- Those with a larger contact angle feature superior axial load resistance.
- Angular contact ball bearings are often preloaded to enhance their rigidity and rotating performance.
- For high-precision matched pair angular contact ball bearings of class 5 or higher, which are used in machine tools and other precision equipment, the standard preload is
specified in three levels: slight (S), light (L), medium (M), and heavy (H).
- When this type of bearing is loaded radially, an axial component of force is produced.
- In this case, two bearings are used together facing one another, or two or more bearings are matched and used.
Double-row angular contact ball bearing
- Consist of two single-row angular contact ball bearings matched back-to-back, with inner and outer rings integrated.
- Accommodates radial load and axial load in both directions.
- Also able to accommodate moment load.
Features Deep Groove Radial Bearing
- The contact angle between the bearing balls and rings is normally 15, 30, or 40 degrees.
- The larger contact angle bearings have greater thrust load capacity.
- Single row bearings can accommodate radial load and axial load in one direction only.
- Double row matched bearings can accommodate radial load and axial load in either direction.
- The DT double tandem arrangement should be used for higher axial loads.
- Angular contact bearings can provide a high degree of accuracy and are capable of running at high speed.
- Cages can be pressed steel, machined copper alloy, molded polyamide, and machined synthetic resin.
Main Applications
- Automotive: Front wheel bearings, transmissions, differential pinion shaft.
- Electrical: High frequency motors.
- Industrial Equipment: Machine tool spindles, pumps, gas turbines, centrifugal separators, and Printing equipment.
