Which type of bearing allows for angular contact in a single row configuration?

• A. Single Row Ball Bearing
• B. Single Row Angular Contact Ball Bearing
• C. Tapered Roller Bearing
• D. Double Row Angular Contact Ball Bearing

Answer: (B)

The choice of a single row angular contact ball bearing is correct because this type of bearing is specifically designed to accommodate axial loads in one direction while allowing for angular alignment of the components. This characteristic is crucial in applications where alignment is necessary to reduce friction and wear between parts, particularly under high-speed conditions.

The design of a single row angular contact ball bearing incorporates a contact angle with the inner race, allowing it to handle not only radial loads but also axial loads in a specified direction. This contrived geometry makes it ideal for applications requiring precise alignment and the ability to handle combined loads, such as in electric motors or machine tool spindles.

Other bearing types mentioned differ primarily in their design and load handling capabilities. Single row ball bearings, while versatile, are not designed to accommodate significant axial loads in one direction due to their configuration. Tapered roller bearings can handle both radial and axial loads, but they require a more complex arrangement and are not classified as single row angular contact types. Finally, double row angular contact ball bearings can manage higher loads due to the additional row but do not fit the criteria of being a single row design, which is crucial to the question asked.

Thus, the specific characteristics and design of the single row angular contact ball
