Ceramic and hybrid bearings

Boca Bearings has expanded its range of full ceramic and ceramic hybrid ball bearings. Ceramic bearings are made of a highly manufactured ceramic, similar to the heat absorbing, super resilient tiles on the Space Shuttle. Ceramic is the perfect material for any application seeking to achieve higher speeds, reduce overall weight or for extremely harsh environments where high temperatures and corrosive substances are present. Ceramic silicon nitride balls for example, exhibit much greater hardness than steel balls resulting in at least ten times greater ball life due to its ability to hold the surface finish longer. The ball has dramatically smoother surface properties than the best steel ball resulting in less friction between the balls and bearing race surfaces. Thermal properties are also improved over steel balls resulting in less heat build up at high speeds. Ceramic has 35 percent less thermal expansion, 50 percent less thermal conductivity, and is lighter in weight and non-corrosive.
