Angular Contact Ball Bearings
Angular contact ball bearings are designed to support combined loads — both radial and axial — thanks to the contact angle between the balls and raceways. This design allows them to accommodate higher axial loads in one direction and makes them ideal for applications requiring high rigidity and precision, such as machine tool spindles and pumps.

Key Features:

  • Designed to handle combined radial and axial loads

  • Contact angle (typically 15°, 25°, or 40°) enables higher axial load capacity

  • Can support axial loads in one direction only (single-row type)

  • Paired bearings can support loads in both directions

  • Provide high rigidity and precision for demanding applications

  • Suitable for high-speed operation

  • Available in single-row, double-row, and four-point contact designs

  • Commonly used in machine tool spindles, gearboxes, and pumps
