Angular contact ball bearings come in various sizes, and their dimensions are typically specified by the bore diameter (d), outside diameter (D), and width (B). Common size ranges include:

  • Bore Diameter (d): From a few millimeters to several hundred millimeters.
  • Outside Diameter (D): Typically ranges from tens of millimeters to several meters.
  • Width (B): Varies depending on the specific design and application requirements.

Sizes are usually standardized, and specific dimensions can be found in catalogs provided by manufacturers.


Single-Row Angular Contact Ball Bearings:

  • Suitable for carrying axial loads in one direction and limited radial loads.
  • Can be paired to accommodate axial loads in both directions.

Double-Row Angular Contact Ball Bearings:

  • Consist of two rows of balls separated by a central rib.
  • Capable of handling higher radial and axial loads.

Four-Point Contact Ball Bearings:

  • Designed to accommodate axial loads in both directions and radial loads.
  • Feature a unique contact angle arrangement, allowing for four-point contact.

Thrust Angular Contact Ball Bearings:

  • Designed specifically to accommodate axial loads.
  • Can support high axial loads and moderate radial loads.


Angular contact ball bearings find applications in various industries, including:

  • Machine Tools: Spindle bearings for precision applications.
  • Automotive Industry: Wheel bearings, gearbox applications.
  • Aerospace: High-speed and precision applications.
  • Robotics: Joint bearings and other critical components.
  • Wind Turbines: Support the main shaft and other rotating components.


The pricing of angular contact ball bearings can vary based on factors such as size, material, precision class, and brand reputation. Prices are typically higher for bearings with tighter tolerances, higher precision, or those designed for specialized applications.


  • Precision Class: Bearings are available in different precision classes (e.g., ABEC 1-9). Higher precision often comes with a higher price.
  • Material: Bearings can be made from various materials, including chrome steel or stainless steel. Specialty materials may affect the cost.
  • Brand: Well-known and reputable brands may have higher prices, but they often come with a track record of quality and performance.
  • Sealing and Lubrication: Bearings with enhanced sealing and lubrication features may be priced higher.

Remember that prices can fluctuate, and it’s crucial to consider the specific requirements of your application when selecting angular contact ball bearings. Always consult with manufacturers or suppliers for the most accurate and current pricing information.
