There are several important advantages to bearing performance that are due to the improved surface characteristics of silicon nitride balls. Because the microstructure of silicon nitride can be uniformly engineered to sub-micron grain size, the surface of a silicon nitride ball can be finished to <0.15 micro-inch Ra and the roundness is often better than 0.00001 tolerance. This precision res... (read more)

CERBEC ® ceramic balls are used in hybrid bearings for a wide variety of applications.

CERBEC Balls are made from two types of silicon nitrides made by Saint-Gobain Ceramics: NBD200 and SN101C. They are both fabricated using glass encapsulation HIPing which assures 100% density, high beta phase content,micron-sized grains, and minimal levels of glass phase.

NBD-200 is a "Magnesia" d... (read more)

SKF® hybrid bearings with silicon nitride rolling elements and steel rings provide insulation against stray currents in large variable speed electric motors to eliminate electric arc bearing damage and resulting premature bearing failure. The ceramic rolling elements further make these bearings lighter, harder … (read more)

MRC hybrid ceramic ball bearings from SKF USA Inc. combine traditional steel rings matched with non-conductive silicon nitride (ceramic) balls offering inherent insulating properties to prevent electrical arcing and associated surface damage to raceways, excessive noise, and premature lubricant aging. They provide ideal "drop-in" replacement solutions ... (read more)
