Ceramic Rolling Bearings

More durable and with even lower rolling resistance than any 2rs bearings they come closer to that magic zero rolling resistance number.

Ceramic rolling bearings. Cerobear is the leading manufacturer of ceramic rolling bearings and a pioneer in rolling bearing technology. We also build ceramic bearings i e bearings with ceramic races but they are not as common because they are less durable. Ceramic bearings are comprised of ceramic rolling elements balls enclosed in a ferrous typically steel inner and outer race. We get more email and blog feedback on the zerø s than any other bearing.

Full ceramic bearings have races and balls that are made entirely of ceramic material and are superior to common steel bearings in many ways. The new ceramtec production line for ceramic cyrol rolling elements is the result of years of development work and meets the technical requirements for silicon nitride roller bearing materials and geometries according to the astm f2730 f2730m class i standard ceramtec s ability to produce at competitive prices comes from the fact that the line is designed for medium to high production. The outer and inner ring of the hybrid ceramic bearing is made from special steel including high carbon chromium bearings steel. Ceramic rolling bearings are a key product for industries and processes with extreme requirements such as the semiconductor and aerospace industries as well as motor sports.

Cage can be made of metallic material resin or composite material depending on the intended operating conditions of the bearing. Since these bearings are constructed from many materials they often operate in hybrid capacities.
