When selecting the right bearing for automotive components and other mechanical applications, one of the most common choices is deep groove ball bearings. These bearings are widely used due to their simple design, low friction, and ability to accommodate both radial and limited axial loads. But an important question arises: Are deep groove ball bearings suitable for handling moments?
Deep groove ball bearings are the most popular type of rolling bearing. Their key features include:
High versatility: They are suitable for use in many industries, particularly automotive components such as alternators, transmissions, and wheels.
Low noise and vibration: Important for automotive components that prioritize smooth performance.
Durability: They can operate at high speeds and require minimal maintenance.
Due to these features, they are often chosen as a reliable solution for automotive component manufacturing and repair.
Torque (or tilting load) occurs when an applied force causes a bearing to tilt rather than rotate smoothly. While well-suited to accommodating radial and moderate axial loads, deep groove ball bearings are not designed to handle large moment loads.
For smaller moment loads, deep groove ball bearings can still perform effectively, especially when used in properly supported shafts.
For larger or continuous moment loads, other bearings, such as angular contact ball bearings or tapered roller bearings, may be a better choice because they offer greater rigidity and stability.
Despite this limitation, demand for deep groove ball bearings in automotive components remains high because most automotive applications do not require them to withstand significant moment loads alone. Instead, they are typically used in pairs or in combination with other bearing types to ensure balanced load distribution.
Examples of automotive components include:
Electric motors and alternators—where speed and efficiency are more important than torque load capacity.
Gearboxes—where compact design and reliability are key.
Wheel hubs (light vehicles)—provide smooth rotation under normal driving conditions.
The answer is: they can handle small to moderate torques, but they are not the best choice for heavy or continuous moment loads. Their advantages in speed, reliability, and versatility make them an ideal choice for automotive applications, especially when combined with proper engineering.
