Ceramic Bearing Vs Hybrid Ceramic

Hybrid bearings sit between full ceramic and steel options.

Ceramic bearing vs hybrid ceramic.

Full ceramic bearings can run without lubrication. Long life and the need for minimal lubrication make this material appropriate for extreme applications. Most sealed ceramic bearings are actually hybrid ceramic bearings which combine a steel race with ceramic ball bearings. Full ceramic bearings on the other hand have ceramic balls and ceramic rings races as well.

Ceramic balls are suitable for applications where high loads high speeds and extreme temperatures are factors. While they use ceramic balls these bearings are paired with metal inner and outer rings. For example while full ceramic bearings do not require lubrication hybrid bearings do. Because of the ceramic balls hybrid bearings cope well with marginal lubrication but they should be adequately lubricated as the ceramic balls will abrade the steel rings much faster if run.

For example while full ceramic bearings do not require lubrication hybrid bearings do. The benefits of ceramic balls are shared by both. Specifying the right bearings for extreme environments has always been a complex issue. Lubrication may not be required when using hybrid bearings at very low speeds.

Despite the small difference in design hybrid bearings requirements differ quite extensively from full ceramic bearings. Using this combination allows for higher speeds. However although the ceramic balls will still abrade the steel rings hybrids will cope with marginal lubrication better than steel bearings due to the low friction coefficient and lightness of the balls. Hybrid bearings typically include stainless steel rings also known by some as races but maintain ceramic balls.

That said a hybrid bearing s corrosion resistance pales in comparison to a full ceramic equivalent. A ceramic bearing is also harder than steel bearings up to 30 which improves durability and they also don t rust so less maintenance should be required. Ceramic is non porous non magnetic non corrosive and lighter than steel. The steel rings in a hybrid bearing will withstand shock loads much better than ceramic rings but in the event of a sudden impact load the much harder ceramic balls will make indentations in the steel raceways leading to rapid wear and early failure.

Ceramic hybrid bearings have steel races and ceramic balls. Ceramic balls on their own are smoother lighter tougher and stronger.
