Angular contact ball bearings are a type of rolling-element bearing designed to handle both axial and radial loads by supporting the shaft in both axial and radial directions. Here’s a guide covering sizes, types, applications, and general pricing information.

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.
