Bones Swiss Ceramics Skateboard Bearings
These bearings are in a class by themselves. If you want the best there is, this is it. The Cerbec Ceramic balls are much lighter, harder, stronger, waterproof, and longer lasting than the finest steel balls. As a result, Bones ceramics will:
Roll faster and farther
Resist dirt and moisture better
Help to repair injuries to your races caused by dirt
Outlast the races, allowing them to actually be reused in most cases.
Single, non-contact, removable rubber shield for easy cleaning and less friction.
High speed Nylon ball retainer for greater strength and speed.
Pre-lubricated with Speed Cream racing lubricant.
Skate Rated clearances, tolerances, materials and lubricant provide the best performance and durability possible.
