Properties advantages of ceramic bearings compared with steel ball bearings: 
1. Higher limiting speeds: Ceramics is lighter than steel and can effectively restrain the centrifugal force, therefore enhancing the limiting speeds.
2. Higher precision usage: Ceramic has a higher hardness and elastic modulus than steel, which means ceramic bearings are more rigid than steel bearings, so therefore can be used in higher precision conditions.
3. Longer life: Lighter ceramic leads to a lower centrifugal force, this will extend the life of the bearing. Furthermore, the friction coefficient of ceramic is lower than steel, which also extends the life of the bearing
4. Higher temperature usage: Ceramic is more mechanically stable at elevated temperatures, therefore they could be used under higher temperatures.
5. Temperature-variation usage: Ceramics has a lower thermal expansion coefficient, and the clearance and tolerance variation is lower than those of steel bearings, which leads to a greater variation in the temperature range.
6. Better seizure resistance: Ceramics has a smaller thermal expansion coefficient; indicating less thermal deformation, therefore enhancing seizure resistance.
7. Could run without oil or grease: Ceramic never rusts and is self-lubricated, therefore can be used in applications that require no oil or grease.
8. Resistant to acid, alkali, and salt: The chemical industry is the largest potential application industry of ceramic bearings to be exploited.
9. More suitable for magnetic applications: Our ceramic bearings are non-magnetic, which means it is difficult for magnetic particles to adhere to the race, therefore reducing particle abrasion.

What is the price range for shielded bearings?

The price range for shielded bearings can vary depending on several factors, including the bearing type, size, brand, quality, and supplier. Here’s a detailed explanation of the price range for shielded bearings:

The cost of shielded bearings can range from a few dollars to several hundred dollars per bearing. The factors that influence the price of shielded bearings are as follows:

  1. Bearing type: Shielded bearings are available in various types, such as deep groove ball bearings, angular contact bearings, cylindrical roller bearings, and more. The price of shielded bearings can vary depending on the complexity of their design and the intended application.
  2. Bearing size: The size of the shielded bearing significantly impacts its price. Larger bearings that can handle higher loads and speeds tend to be more expensive than smaller bearings.
  3. Brand and quality: Well-known and established bearing brands typically command higher prices due to their reputation for quality and reliability. These brands often invest in research and development, precision manufacturing processes, and quality control measures to ensure their bearings meet or exceed industry standards. Lesser-known or generic brands may offer lower-priced shielded bearings, but their quality and performance may vary.
  4. Supplier and quantity: The supplier or distributor from which the shielded bearings are purchased can also affect the price. Different suppliers may offer different pricing structures or discounts based on factors such as order quantity, customer loyalty, or special promotions.
  5. Application-specific requirements: In some cases, shielded bearings may need to meet specific requirements or industry standards, such as high precision, high temperature resistance, or special certifications. Bearings designed for specialized applications or industries may come with a higher price tag due to the additional engineering and manufacturing considerations.

It’s important to note that the price of shielded bearings is usually indicated per bearing. If multiple bearings are required for an application, the total cost will depend on the quantity needed.

To get an accurate price range for shielded bearings, it’s recommended to contact bearing suppliers or distributors directly. They can provide detailed pricing information based on the specific requirements, quantity, and other factors relevant to the application. Comparing prices from different suppliers and considering the overall value, including quality, reliability, and service, is crucial in making an informed decision.

How to maintain and clean shielded bearings?

Proper maintenance and cleaning are crucial for ensuring the optimal performance and longevity of shielded bearings. Here’s a detailed explanation of how to maintain and clean shielded bearings:

  1. Regular Inspection: Periodically inspect the shielded bearings for any signs of damage, wear, or contamination. Check the shields for dents, deformations, or loosening. Inspect the rolling elements and raceways for signs of pitting, scoring, or abnormal wear. If any issues are found, replace the bearing or take appropriate corrective actions.
  2. Clean Work Environment: Before performing any maintenance on shielded bearings, ensure that the work area is clean and free from dust, dirt, and other contaminants. This helps minimize the risk of introducing particles into the bearing during maintenance.
  3. Use Proper Tools: When handling shielded bearings, use appropriate tools and equipment to avoid damaging the shields or internal components. Avoid using tools with sharp edges that can scratch or deform the shields.
  4. Cleaning Procedure: To clean shielded bearings, follow these steps:
    1. Remove the shields: Carefully remove the shields from the bearing using suitable tools. Be gentle to avoid damaging the shields or bending them out of shape.
    2. Clean the shields: Clean the removed shields using a mild solvent or degreaser. Gently wipe away any dirt or debris using a soft, lint-free cloth. Avoid immersing the shields in solvents for an extended period as it can damage the shields.
    3. Clean the internal components: If necessary, clean the internal components of the bearing using a suitable solvent or degreaser. Use a soft, lint-free cloth or a soft-bristle brush to remove any dirt or old lubricant. Ensure that the solvent used is compatible with the bearing material.
    4. Dry the components: Allow the cleaned shields and internal components to air dry completely or use a low-pressure air source to remove any residual solvent or moisture.
    5. Lubricate the bearing: Apply an appropriate lubricant to the cleaned internal components. Follow the manufacturer’s recommendations for the type and amount of lubricant to be used.
    6. Reinstall the shields: Carefully reinstall the cleaned shields onto the bearing, ensuring they are properly aligned and securely seated.
  5. Relubrication: Depending on the operating conditions and manufacturer’s recommendations, shielded bearings may require periodic relubrication. Monitor the lubricant condition and replenish it as needed. Follow the manufacturer’s guidelines for the relubrication interval and the type of lubricant to be used.
  6. Document Maintenance: Keep a record of the maintenance activities performed on the shielded bearings, including the date, cleaning procedure, lubrication details, and any observations or issues. This documentation can help track the maintenance history and plan future maintenance activities.

It’s important to note that the maintenance requirements may vary depending on the specific application, bearing type, and operating conditions. Always refer to the manufacturer’s instructions and guidelines for the proper maintenance and cleaning procedures of the shielded bearings.

By following these maintenance and cleaning practices, you can ensure the optimal performance and longevity of shielded bearings, minimizing the risk of premature wear, contamination, or failure.
