A Single Row Angular Contact Bearing is a type of rolling-element bearing specifically designed to support combined loads—radial and axial (thrust)—but primarily in one direction. Here’s a detailed breakdown:

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.
