The ZERO line is the best option for high-performance ceramic bearings for athletes who demand the most from their equipment, however, it is more suitable for wheels. Due to a cryogenic treatment, these bearings guarantee greater hardness and longevity, in addition to lower sliding resistance than any other bearing, hence the name “zero”, almost zero resistance.
These are the roundest spheres you can buy without a military license.
Enduro Bearings uses silicone seals that are more slippery than the rubber seals used by other ceramic bearing suppliers.
Si3N4 balls and a 52100 Races body of cryogenically treated high carbon chromium alloy: The cryogenic treatment brings the corp down to less than three hundred degrees Fahrenheit to normalize the crystalline structure of the material so that the body will resist the hardness of ceramic balls and obtain maximum wear potential.
