Full ceramic wheel bearings would be an amazing way to reduce friction in hubs.
Full ceramic engine bearings.
Ceramic is the perfect material for any application seeking to achieve higher rpm s reduce overall weight or for extremely harsh environments where high temperatures and corrosive substances are present.
The problem here is that wheels take hard impacts from potholes.
Full ceramic bearings constructed entirely of ceramic material.
Full ceramic bearings are lighter smoother stiffer harder corrosion resistant and electrically resistant.
Full ceramic bearings have races and balls that are made entirely of ceramic material and are superior to common steel bearings in many ways.
Studies show that ceramic bearings can last anywhere between 5 and 20 times longer.
The smoother surface of the ceramics also significantly reduces the risk of bearing seizure with little to no lubrication.
Inner outer races and balls are made of either silicon nitride si3n4 zirconium oxide zro2 or silicon carbide sic.
Furthermore ceramic bearings can operate in harsh.
Boca bearings is the leader in ceramic and ceramic hybrid bearing technology for industrial and recreational applications.
Full ceramic bearings are used in extreme and in special environments like operating temperature.
Ortech manufactures 6312 full ceramic bearings for extend service life reduce wear and minimize friction applications.
After all since there are no chance for parts to oxidize there is also no need for grease.
