3. Longer Service Life: Shielded bearings often boast a longer service life by effectively preventing contaminants from entering and retaining lubrication. This is particularly beneficial in applications where bearings are subjected to harsh conditions.
4. Lower Friction: Shielded bearings typically exhibit lower friction than sealed bearings. The shields do not contact the inner ring, cage, or balls. Lower friction often translates to higher efficiency and less energy consumption in machinery.
5. Easier Maintenance and Handling: Since shielded bearings do not have seals that contact the rolling elements, they are generally easier to handle and maintain. They can be cleaned and inspected with less difficulty, which is beneficial in environments where bearings need to be regularly checked for wear and damage.
6. Cost-Effectiveness: Shielded bearings can be more cost-effective than sealed bearings because they typically require less stringent manufacturing processes for the shielding compared to sealing. This can make them a more economical option when conditions do not need full sealing protection.
7. Suitable for High-Speed Applications: Shielded bearings are often preferred in high-speed applications because they generate less heat due to reduced friction. Sealed bearings, by contrast, might not perform as well under high-speed conditions due to increased friction from seal contact.
8. Versatility: They are suitable for a wide range of applications. While they are not ideal for extremely dirty or wet environments (where sealed bearings might be preferable), they work well in various general engineering and industrial applications.
9. Availability: Shielded bearings are widely available in various sizes and designs, making them easy to integrate into numerous types of equipment without requiring special adjustments or components.

Correct selection and use of Shielded Bearings
Understand application requirements:
First, clarify the specific requirements of your equipment or system for bearings, including load, speed, working environment (such as temperature, humidity, pollutants, etc.), and electromagnetic environment.
Evaluate whether electromagnetic shielding is required and what level of shielding effectiveness is required.
Choose the right type and size:
According to the application requirements, select the appropriate bearing type (deep groove ball bearings, cylindrical roller bearings, etc.) and specifications (such as inner diameter, outer diameter, width, etc.).
Ensure the load and speed ratings of the selected bearings meet or exceed your application needs.
Consider materials and coatings:
Select a bearing material suitable for the working environment and consider factors such as corrosion resistance, wear resistance, and thermal stability.
Special coatings or surface treatments may be considered if additional electromagnetic shielding or corrosion protection is required.
Refer to manufacturer recommendations:
Communicate with shielded bearing manufacturers to learn about their product features and recommended applications.
Use the manufacturer’s recommendations and specifications to select the bearing best suits your application.
Correct use of Shielded Bearings
Install correctly:
Follow the installation guidelines and recommendations provided by the manufacturer to ensure that the bearings are installed correctly and to the intended accuracy.
Use appropriate tools and methods to avoid damaging the bearing or affecting its performance during installation.
Maintenance and care:
Check and maintain bearings regularly to ensure they are in good working order.
Perform necessary lubrication and cleaning according to manufacturer’s recommendations to extend bearing life.
Pay attention to the electromagnetic environment:
Avoid the influence of strong electromagnetic fields or electromagnetic interference sources when using shielded bearings.
If possible, appropriate electromagnetic shielding measures should be taken to improve the electromagnetic performance of the bearing further.
Logging and monitoring:
Record bearing usage and performance data so potential problems can be identified and dealt with promptly.
A monitoring system is used to track the condition of the bearing in real time to ensure it maintains optimal performance throughout its use.
This bearing adds a shielding layer of conductive material on the inner and outer rings or rolling elements to reduce or eliminate electromagnetic interference. It is particularly suitable for equipment in high electromagnetic field environments, such as motors, generators, and transformers.2. Sealed and shielded bearings:
In addition to its electromagnetic shielding function, this kind of bearing also has excellent sealing properties, which can prevent liquid, dust, and other contaminants from entering the inside of the bearing. They are often used in applications that require high cleanliness or reliability, such as food processing, medical devices, and aerospace.
3. High-temperature shielded bearings:
This bearing uses special materials and designs to maintain stable performance and an electromagnetic shielding effect in high-temperature environments. It is suitable for high-temperature working environments such as high-temperature furnaces, heat treatment equipment, and thermal machinery.
4. High-speed shielded bearings:
Shielded bearings specially designed for high-speed rotation can withstand the centrifugal force and frictional heat caused by high rotational speeds while maintaining stable electromagnetic shielding performance. They are commonly used in high-speed motors, wind turbines, and machine tools.
5. Stainless steel shielded bearings:
Stainless steel shielded bearings have excellent corrosion resistance and mechanical strength. They are suitable for wet, corrosive environments or applications requiring high-strength support.
