We provide Si3N4 material ceramic roller and Si3N4 ceramic ball for his bearings .

We can produce ceramic roller and balls all accoring to your requirements ,such as G2 ,G10 grade ,different dimension and tolerance.

For cermic material ,we can produce with belows type :

zirconia

extremely durable zirconia ball blanks are ideal for severe-service environments like oil & gas down-hole, chemical manufacturing, and other high-pressure, high-temperature, and corrosive applications.

used as components for valves, check valves, flow control, and flow measurement, zirconia ball blanks are available in many sizes.

alumina

alumina (aluminum oxide) ball blanks are abrasion resistant, high hardness, and thermally stable at temperatures up to 1800° c — useful in oil & gas down-hole, chemical pump applications, and as part of valves, bearings, flow meters, and more.

silicon nitride

silicon nitride has the most versatile combination of mechanical, thermal, and electrical properties of any technical ceramic material. it is a high performance technical ceramic that is extremely hard and has exceptional thermal shock and impact resistance. it surpasses most metals high temperature capabilities and has a superior combination of creep and oxidation resistance. Additionally, its low thermal conductivity and high wear resistance make it an excellent material that can withstand the toughest of conditions in the most demanding industrial applications. silicon nitride is an excellent choice when high-temperature and high -load abilities are needed.

bearings & valve balls

high-precision ceramic bearings, high temperature bearings, vacuum bearings, non-magnetic bearings, chemical pumps, high temperature pumps, ceramic valve balls, measuring balls.

ZZ BEARINGs can produce high-quality silicon nitride ceramic bearing balls The specifications are from 0.4mm to 60mm in diameter, and the machining accuracy is G5, G10, G20, G40-G100.
