Alumina oxide or Al2O3 is a very common material in the ceramic’s world. It’s not as common for bearings but UNASIS bearings can still be supplied when the situation arises. Recent advancements in biomedical engineering have shown that alumina ceramic bearings have shown superior wear resistance and eliminate the risk of ion release. This makes this material highly compatible for use within the human body.
Alumina bearings are non-magnetic, non-conductive, run lubrication free, have a high hardness and wear resistance. Please reach out to Carter Bearings to see if alumina bearings are the correct ceramic bearing option for you.
