Moto Premium Swiss Bearings are the most technologically advanced and visually stunning bearings in roller-skating. Moto Premium Swiss Bearings are built with precision Swiss parts that are bonded with an extremely hard “TiNite” ceramic coating, and also feature the industry’s only “oil thru” shields, that ensure proper lubrication to all the internal parts. This “TiNite” coating process hardens the running surfaces and not only improves durability and glide, but also reduces friction, which requires less oiling. This process also gives Moto Premium Swiss Bearings its ‘rainbow like’ coloring that is unlike any other.
