Ceramic Bearings
Ceramic bearings are generally constructed from ferrous inner and outer rings, filled with ceramic rolling elements instead of steel ones. The rolling elements themselves are typically made from ceramic silicon nitride, which is harder and smoother than most steel bearing balls. The result is a bearing with higher speed and acceleration capability due to lower friction, and greater precision due to increased stiffness. Furthermore, ceramic bearings not only require less lubricant, but exhibit less lubrication degradation and are resistant to oxidation, resulting in longer life.
Typical applications include aircraft accessories, semiconductors, food processing machines, dental handpiece turbines, and other machinery that creates high temperatures, friction, or speed.

The Timken Company
The Timken Company offers ceramic hybrid ball bearings from a size range of 10 mm - 200 mm (0.3937 in. - 7.874 in.) bore . The bearings are a result of ceramic rolling elements combined with super-finished steel rings. The balls are lightweight and made of silicon nitride. The bearings can be ordered with or without seals and to include custom preloads, 15° or 25° contact angles, and designs to ISO/ABMA 02, 10, 19 specifications.CantonState: OHCountry: USA -
Bearing Works
Bearing Works Inc. provides full ceramic ball bearings. These ball bearings are anti-friction and completely made of ceramics. The inner races, outer races and balls are either made of silicon nitride or zirconium oxide. The bearings have a temperature capacity of 1800°F. The lightweight feature of these bearings not only reduces weight but also reduces vibration effects and increases speed. Significant features include non magnetism, corrosion resistance, electrically non-conductive, and thermal insulation.Country: USA -
