Utilizing precision Swiss-made hardened chromium steel alloy balls and lightweight friction-resistant Delrin® retainers, the races of the KwiK® Swiss Nitride bearings – the surface where friction is created with alloy balls – are coated with a thin coating of Titanium Nitride, a durable chemical-resistant compound that will not chip, dissolve, or otherwise degrade even during the most extreme skating conditions. The Titanium Nitride coating finishes the races of the KwiK Swiss Nitride bearings in a beautiful metallic gold appearance and also strengthens them to produce the fastest, longest roll available today.
