Technically, the OSPW system is equipped with high-performance bearings and special ceramic balls made of third-grade silicon nitrite (best grade achieved for ceramic bearings). The ball bearing cage is made of reinforced polyamide, with a hardened steel race and polished groove. The CERAMICSPEED bearing balls are 15% harder, 100% more flexible and 99% more resilient than standard ceramic balls. CERAMICSPEED bearings are considered to be the best ceramic bearings worldwide.
