Ceramic Bearings and Balls for Turbine Flowmeters

A line of ceramic balls and stainless-steel, ceramic-hybrid, and full ceramic bearings are now available for turbine flowmeters.

Using ceramic bearings extends the service life of flowmeters because their nonporous, glasslike surface is virtually frictionless and, therefore, requires little or no lubrication to operate. Ceramic is also suitable for extremely high or low temperature applications with in the range of –100 to 900°C (–148 to 1,652°F).

The bearings also come in stainless steel, alumina oxide ceramic, silicon nitride ceramic. and heavy-duty plastics, as well as in many different styles, including radial deep groove bearings, thrust bearings, and angular contact bearings.
