Product Description

Full Zirconia Ceramic Ball Bearing

 

Zirconia Ball Bearing is ceramic balls that are inert to corrosive materials with the exception of hot,concentrated sulfuric acid. Zirconia has a maximum useful temperature of 1800° F. Compressive Strength. 794,837 psi.They are able to run without lubrication, have low thermal expansion, are normally low density and have non-magnetic qualities.However, they are expensive, have low load capacities, are sensitive to thermal shock and are difficult to achieve a high quality of surface finish on.

 

Applications For Full Ceramic Bearings: > MRI equipment > vacuum environments > semiconductor manufacturing > radiotherapy > food processing industrie > any extreme environment requiring non-corrosive, non-conductive or non-magnetic bearings

 

Benefits Of Full Ceramic Bearings: > resistant to acid, salt and water, and blood > non-magnetic > lower coefficient of friction > resistant to electricity > corrosion-resistant > lighter, smoother and stiffer
