A Comparison of the Application Scenarios of Deep Groove Ball Bearings and Angular Contact Ball Bearings

In the huge system of industrial machinery, deep groove ball bearings and angular contact ball bearings belong to the ball bearing family, but they have significant differences in application scenarios. The correct selection of suitable bearings is crucial to the efficient operation, cost control and service life of the equipment. Today, we will deeply analyze the unique performance of these two kinds of bearings in different scenarios.

Deep Groove Ball Bearings: Widely Used “All-rounder”

Home Appliance Field

In household appliances, deep groove ball bearings are extremely common. In the case of the washing machine bucket, it mainly bears radial force when rotating at high speed, and the deep groove ball bearing can easily cope with this condition by means of its simple structure, small friction coefficient and high limit speed. As the key parts of bearing ball rolling, the smoothness and accuracy of bearing races have an important impact on the performance of bearings. High-quality bearing races can effectively reduce the friction between the ball and the raceway, so that the bucket can be smoothly and efficiently rotated, thereby reducing energy consumption and noise. In air conditioning compressors, electric fans and other household appliances, deep groove ball bearings also play a vital role, effectively ensuring the stable operation of the equipment. Because home appliances are more sensitive to cost, and the manufacturing cost of deep groove ball bearings is low, which makes them have a strong competitiveness in the field of home appliances.

Miniature Motor

Small motors are widely used in various industrial equipment and automated production lines. Deep groove ball bearings in small motors can effectively withstand the radial load of the motor rotor to ensure the stability of the motor when rotating at high speed. In some small motor drives in automated production lines, roller guides, combined with deep groove ball bearings, can achieve accurate linear motion control. The low friction characteristics of deep groove ball bearings can reduce energy loss, and improve the efficiency of the motor, and their installation and maintenance are relatively simple, which is an important advantage for applications where frequent replacement or maintenance of the motor is required.

Angular Contact Ball Bearings: High-precision, High-load “Professional Players”

Machine Tool Spindle

Machine tools require very high accuracy and stability, and angular contact ball bearings are very critical in machine tool spindles. It can bear large radial and axial loads at the same time, and improve the rigidity and rotation accuracy of the spindle by adjusting the preload. The manufacturing accuracy of bearing races, the properties of materials and the design of bearing cages greatly affect the performance of angular contact ball bearings. In precision machining such as high-speed milling and precision grinding, the spindle of the machine tool needs to rotate at high speed and maintain high precision positioning, and the characteristics of the angular contact ball bearing enable it to meet these requirements. Despite the high cost, it is an indispensable choice in machines that require extremely high accuracy and performance.

Aero-engine

Aero-engine is the core component in the aviation field, the working environment is harsh, and the bearing performance is demanding. Angular contact ball bearings are used to support the rotor system, withstand axial and radial loads, and adapt to high temperature, high speed and high vibration conditions. The bearing cages are made of high-strength, high-temperature resistant materials and can guide and isolate the ball under extreme conditions. Roller guides are used in auxiliary systems such as inlet regulating mechanisms, which combine with angular contact ball bearings for precise position control and motion guidance and rely on high-precision technology and special materials to maintain stability in extreme conditions. Like the compressor and turbine parts, the operation of angular contact ball bearings is critical to engine efficiency and safety. Although the requirements are high, from the perspective of operating cost and safety, it is the key to the normal operation of the engine.

Deep groove ball bearings and angular contact ball bearings play an irreplaceable role in their respective application scenarios. Understanding their performance characteristics and application scenarios, as well as the role of key components such as bearing races, bearing cages and roller guides, can help engineers and equipment manufacturers make more informed choices.
