Ceramic bearing cage material

Ceramic Hybrid Bearings: Standard steel race bearings (chrome or stainless steel) which have been refitted with ceramic balls, or manufactured with ceramic balls-the results are higher speed, extended operating life, less lubrication, and corrosion resistance. Other features are high stiffness, low torque, long wear life, and lighter weight.

Solid Film Lubricants: Special bearing coatings are available for extreme high temperature and chemical environments that standard bearings just cannot handle. Ball bearings often suffer premature failure due to galling caused by a lack of lubrication. We have several types of dry lubricants available for different applications. Please check with your sales rep for the dry film, which will handle your application.

Hybrid bearings eliminate scarring of races
Advanced motors can electrically damage steel bearings. The inner and outer races of antifriction bearings often become frosted, fluted, or get corrugated pattern imprinted on them. These are not mechanical scars but are due to electromagnetic forces and can lead to bearing failure. They are usually found in modern systems that routinely feature pulse-modulated adjustable-speed motors and inverters with high switching frequencies and short rise times. These designs can transmit the rotor voltage through the motor shaft because voltage exceeds the dielectric strength of lubricants on the bearings. The resulting current flows from the shaft and lubricant, causing the frosting, fluting, and generating the corrugated pattern.
