Full Ceramic Bearings from Boca Bearings
Written by Sergio Sebastian-Spain
Revista DH, Nov 2010
Full ceramic bearings are made entirely of Zirconia ceramic for the races and Silicon Nitride for the balls which is superior to conventional steel bearings in many respects. The ceramic is a perfect material without any pores or imperfections as opposed to steel which has pores, pits and gaps on the surface. Ceramic is also a very light weight material, which can achieve more RPM
