(Cox Instruments: Scottsdale, AZ) -- COX Instruments, a supplier of precision and industrial flow measurement instrumentation for the world’s most demanding applications, has announced its turbine flowmeters are now available with ceramic ball bearings. These rugged bearings are superior to standard 440C stainless steel and journal bearings in terms of wear resistance, and are less susceptible to fluid particulates. They are ideal for water and cryogenic applications, which have little to no lubricating properties.

In a wide range of applications, turbine flowmeter users must select the proper bearing material for fluid lubricity and process temperature to ensure long-term reliability. Water applications in particular may require high-friction journal bearings, which can shorten the meter’s linear flow range of operation. Ceramic ball bearings, on the other hand, have a low coefficient of friction and exhibit excellent wear-resistant characteristics. They are also an excellent choice for high-temperature applications, with temperatures up to 425°C (800°F).
