Ceramic Bearings Def

Long life and the need for minimal lubrication make this material appropriate for extreme applications.

Ceramic bearings def.

Thermal shock is when the temperature gradient within the material causes a differential expansion which results in an internal stress. A ceramic material is an inorganic non metallic often crystalline oxide nitride or carbide material. Ceramic hybrid bearings ceramic hybrid bearings have steel races and ceramic balls. Some elements such as carbon or silicon may be considered ceramics ceramic materials are brittle hard strong in compression and weak in shearing and tension.

They withstand chemical erosion that occurs in other materials subjected to acidic or caustic environments. This stress can exceed the strength of the material thus forming a crack. Hybrid bearings have rings made of bearing steel and rolling elements made of bearing grade silicon nitride si 3 n 4 which make the bearings electrically insulating. They are highly resistant to acids and alkalis and are.

Ceramic bearings have lower load capacities in comparison to metals and are sensitive to thermal shock. Silicon nitride rolling elements can extend bearing service life by offering enhanced bearing performance even under difficult operating conditions.
