Angular contact ball bearings have inner and outer ring raceways that are displaced relative to each other in the direction of the bearing axis. This means that these bearings are designed to accommodate combined loads, i.e. simultaneously acting radial and axial loads.

Key Characteristics:

Contact Angle:

• The inner and outer ring raceways are displaced relative to each other in the direction of the bearing axis.
• Standard contact angles are typically 15°, 25°, or 40°.
• A larger contact angle = higher axial load capacity, but lower speed capability.

Load Handling:

• Radial loads (perpendicular to the shaft) and axial loads (parallel to the shaft) in one direction only.
• To handle axial loads in both directions, they are usually mounted in pairs (back-to-back, face-to-face, or tandem).

Precision and Speed:

• These bearings are ideal for high-speed and high-precision applications, such as machine tool spindles.
