The Bones Swiss Ceramic bearings have ceramic ball bearings with a Swiss steel casing. Ceramic is naturally waterproof and is harder, lighter, and stronger than steel. It produces less friction which creates a fast and long lasting bearing. The one sided, non-contact, removable rubber shield provides easy maintenance. The retainer is produced with high speed nylon for strength and speed.
