Ceramic Bearings Application

Hybrid bearings ceramic steel or chrome the following are the basic properties of hybrid bearings figure 3.

Ceramic bearings application.

Much of the modern material we find common place today can find there origins in pioneering space technology the same can be said for many of the advanced ceramic materials used in bearings. A tiny percentage reduction in friction here can equate to a worthwhile power saving but when you re only turning at 300 rpm as you do on a bicycle a small percentage increase in efficiency will make a negligible change to your power output. Ceramic bearings are typically constructed with a ferrous inner and outer ring or race with ceramic balls in the place of steel. The lightweight and vacuum compatible bearings make them ideal for satellites and spacecraft which require optimal weight capacities to enhance flight dynamics and acceleration.

Silicon nitride bearings have found use in a myriad of applications including laptop smartphones modelism bicycles skate board and rollers. Ceramic bearings offer many advantages over all steel bearings such as higher speed and acceleration capability increased stiffness lower. Catastrophic failure of ceramic bearings in vivo fig. They ceramic bearings do run with less friction which offers a significant advantage in industrial applications running at 20 000 rpm.
