Sonic Ceramic Bearings use ceramic (Si3N4) balls, which are rounder and smoother than steel. This allows for less friction and more speed! Ceramic balls are also harder than steel and up to 60% lighter, lasting up to 10 times longer without corrosion. Deep groove races are made from premium Japanese SUJ2 chrome steel. Nylon ball retainer makes them light and quiet, while a labyrinth seal works to keep out dirt and debris to prolong bearing life. Fully serviceable (remove non-contact rubber seals) and pre-lubricated with Sonic Super Gel.
