Ceramic balls, especially silicon nitride balls, have characteristics of low density, high hardness, low friction coefficient, anti-magnetic and electrical insulation, wear-resisting, self-lubricating and rigidity, etc.. Especially ceramic balls are suitable for high speed, high precision and long life mixing ceramic ball rolling. (Inner ring and outer ring are metal). Generally speaking, inner and outer rings are steel (GCr15) or stainless steel (AIS440C, 316 304) and ceramic balls can be Zr02, Si3N4 or SiC.

Ceramic ball bearing: With the development of high-speed operation, ceramic materials (mainly refers to Si3N4) become the ideal material for high-speed precision bearings due to a small density, high elastic modulus, small expansion coefficient, wear resistance, high temperature, corrosion resistance and other characteristics. Our high-speed precision ceramic bearings rolling ceramic are made of Si3N4, both inside and outside the circle are mixed steel bearing ceramic ball bearings and the accuracy level is up to P4 or more.


Characteristic:
1. With a resistance of a variety of strong acid, alkali, salt and other corrosive media erosion, high temperature, wear-resistant.
2. Structure of light weight, high speed limit, electrical insulation, high temperature stability. The starting torque is small.
3. Can be used in harsh working conditions, with a high service life.

Applications:
Widely used in the fields of aviation, aerospace, navigation, petroleum, chemical, machinery, automobile, locomotive, metallurgy, electric power, textile, pump, pharmaceutical, food machinery, medical instrument, scientific research and national defense and military technology.
