Alumina Bearings

Share This Page

Alumina oxide (Al2O3), whilst being very common in the wider world of ceramics, is not typically used in bearings but can be supplied when the situation arises. Recent advancements in biomedical engineering have shown this material is highly suited for use within the human body due to its superior wear resistance and the fact that it eliminated the risk of ion release.


Our alumina bearings have high-hardness, run lubrication-free, and are non-magnetic and non-conductive. Please get in touch with our team today to find out of these bearings are the correct choice for your next project.
