Why choose a ceramic IMS bearing
When sintered silicon nitride balls are used in ceramic hybrid ball bearings there are many benefits to these advanced ceramics over conventional steel balls including: no cold welding or adhesive wear and with lowered centrifugal forces ball-skidding is minimized 5 Beyond spalling caused by mechanical overload which is commonly seen in original IMS bearings adhesive wear and ball
What is silicon nitride? aluminum foundry high speed bearing
Silicon Nitride is one of the hardest substances in the world Its high strength low density and high temperature resistance makes it a suitable material for various harsh conditions Si3N4 ceramic is a covalent bond compound The basic structural unit is a [SiN4] tetrahedron The silicon atom is located at the center of the tetrahedron

Are ceramic bearings worth the cost?
Mar 05 2020Using bearings made from silicon nitride rather than the standard alumina (aluminum oxide) provides electrical insulation and good corrosion resistance Silicon nitride's resistivity and dielectric constant are similar to that of alumina but the material is far stronger due to its microstructure

Bearing It All: Ceramic Bearings
Finally ceramic bearings are lighter because ceramic is less dense than steel (silicon nitride for instance has a 60 percent lower density than steel) When combined with special seals and optimized lubrication the friction in ceramic bearings can be 20- to 30-times lower than steel bearings with standard seals and lubrication
