Kwik Swiss Nitride

The ball bearings of the KwiK Swiss Nitride Ball Bearings - the surface where friction with alloy balls occurs - are coated with a thin layer of titanium nitride, a durable alloy of precision-ground hardened chrome steel alloy balls and lightweight, friction-resistant Delrin® retainers, a chemical-resistant compound that will not flake, dissolve, or otherwise degrade even under the most extreme conditions.

The titanium nitride coating completes the races of the KwiK Swiss Nitride ball bearings with a beautiful metallic gold look, making them among the fastest ball bearings currently available.
