ABEC-5 tolerances and LLB seals with Graphite Nylon retainers are premium features that are not available on other ceramic hybrid bearings at two or even five times the cost. Oversized Silicon Nitride (Si3N4) Grade 5 balls and cryogenic treatment of the ABEC-5 races ensure long lasting, smooth rolling bearings at great value. 60% lighter weight and 7 times harder than steel, friction is reduced to near zero. Resistance to heat is 8 times greater than that of steel, while tougher and less brittle than other ceramic materials.
