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.
