Ceramic Ball Bearings Eliminate Arcing (November 01, 2003)

Koyo 3NC hybrid-ceramic ball bearings eliminate electric arcing or fluting by insulating the bearing. Featuring low temperature rise at high speeds and high resistance against seizure, they allow performance at speeds up to 50% higher that steel bearings, because ceramics are 60% lighter. Other benefits include good rigidity and long grease life.
