ADVANTAGE
# Stainless Steel, Ceramic Hybrid, Orange Sealed bearings are specially designed for any application seeking a high precision, free spinning bearing. These are the true secret weapon for serious rc racers and long distance casters. ABEC 7 tolerances makes the Orange Seal line the closest precision tolerance that Bearings has to offer. The removable, non-contact rubber seals results in a bearing with less drag and that requires less maintenance than a typical shielded bearing. The Grade 5 ceramic Si3N4 balls will allow the bearing to be lighter and spin 50% faster than a traditional steel bearing.

# Ceramic by its nature is lighter than steel by about 2/3 the wieght, it is harder than steel when it is in ball form and it is virtually frictionless because it is non-porous. A ceramic hybrid bearing has steel races with ceramic balls. The balls will never corrode or rust.
