How to tell if bearings are hybrid ceramic bearings?

2025-03-11

Check the Product Label or Manual: Look for words like "hybrid," "ceramic balls," or "silicon nitride (Si3N4) balls" in the product description or manual. This information will tell you if it's a hybrid ceramic bearing.
Examine the Bearing Number: Sometimes, the bearing model number might include hints that it’s a hybrid type. However, this can vary by manufacturer, so checking the specific naming rules from the maker can help.
Magnet Test: Ceramic doesn’t attract magnets. You can use a small magnet to see if the balls inside the bearing are attracted to it. If they are not attracted, they are likely ceramic.
Compare Weights: Ceramic balls are lighter than steel ones. Compare the weight of your bearing with a known steel bearing of similar size. The lighter one is probably a hybrid ceramic bearing.
Ask the Supplier: If you’re unsure, simply ask the supplier or check the manufacturer’s website. They can confirm whether the bearing is hybrid ceramic.

Remember to handle the bearings carefully to avoid any damage. If you're uncertain, always refer back to the original documentation or contact the supplier directly.
