Unlike others, we match the hardest ceramic balls with the hardest available races. This
means no soft stainless steel races. Our races are hardened chromium steel, cryogenically
treated and polished to make them the best possible match for the ceramic balls. The ZERŲ bearings include a Magnetite
rust-proof finish and USA-made Grade 3 ceramic balls.
