BULLSEYE Skateboard Inline BEARINGS - ABEC 5 - 20 TUBES

Making a great bearing starts with having the a lot of expertise, and using the best materials. Bullseye uses super hard Chrome Steel balls that measure 65 on the Rockwell Scale; each ball is tested to ensure that is perfectly round. The balls run in deep-grove race ways, and are retained by a self-lubricating Delrin crown. A low viscosity synthetic oil bas been added to make these bearings spin great, while keeping friction levels at a minimum. Each bearing feature dual rubber shields(seals) to protect the bearing from dust and other contaminates. The shields also make this bearing completely serviceable.
