Which type of bearing is designed to handle heavy radial and axial loads while maintaining accuracy?

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

Answer: (C)

The double row angular contact ball bearing is specifically engineered to accommodate both heavy radial and axial loads while providing high levels of precision. This design features two rows of balls that contact the raceway at an angle, allowing it to effectively handle forces coming from multiple directions. This capability makes it ideal for applications where both load types are present.

Additionally, the double row design offers increased load-carrying capacity relative to single row bearings, enabling these bearings to maintain operational accuracy even under significant stress. This combination of durability and precision is essential in various mechanical systems, particularly those that require reliable performance under substantial load conditions.

In contrast, the other bearing types included in the options may excel in specific applications but do not provide the same combination of features. For instance, single row ball bearings are generally better suited for applications with lighter loads, while tapered roller bearings are primarily focused on handling axial loads in one direction. Cylindrical roller bearings offer high radial load capacity but lack the axial load management that angular contact designs provide, leading them to be less suitable for applications demanding precision under combined loading conditions.
