Full Ceramic ABEC 5 radial bearing with 15 mm inner diameter, 28 mm outer diameter, 6/7 mm thickness and low friction silicone sealing.
Full ceramic bearings constructed entirely of ceramic material.
Made from pure Silicon Nitride material (Si3N4) with extreme high density from uniform compaction (3.25 g/cm3), the micro-structural elements of this material is second to none. In other words, it is extremely dense, hard and fast. There are several materials used for ceramic balls and races and Enduro Bearings only use the best, Grade 3 Silicon Nitride. 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, tougher and less brittle than other ceramic materials. There is simply no comparison for corrosion resistance or magnetic problems with their Si3N4 balls.
Full Ceramic require special tools and proceedures. The warranty voided by non approved installers.
