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. Ceramic balls are suitable for applications where high loads high speeds and extreme temperatures are factors. This stress can exceed the strength of the material thus forming a crack. Ceramic bearings full ceramic bearings have ceramic rings and balls and either a synthetic cage made from peek or ptfe or no cage at all.

Silicon nitride rolling elements can extend bearing service life by offering enhanced bearing performance even under difficult operating conditions. Thermal shock is when the temperature gradient within the material causes a differential expansion which results in an internal stress. 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. A ceramic bowl spills over with a hearty stew of calamari shrimp flanks of fish mussels and scallops in a mild and vaguely sweet tomato fennel sauce my companions tried baked bacon and baked cheese dishes that also weighed in at 450g and were served sizzling hot in ceramic bowls.

They withstand chemical erosion that occurs in other materials subjected to acidic or caustic environments. Ceramic bearings have lower load capacities in comparison to metals and are sensitive to thermal shock.
