Angular Contact Ball Bearing with Machine Cage (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.
