Ceramic Sliding bearings are a most common bearing used in machines, pumps, similar devices besides roller bearings. These kind of bearing could make good use of their low friction and self-lubrication properties to use in limited space and design demand movement stable applications.
Since there is a direct contact between rotating machines' components and bearings, friction force is an inevitable issue of them. The friction will significantly reduce the service lifespan. So the low fricition parameter, high wear resistance, middle bearing pressure, load range (Sommerfeld number), storage temperature, relative bearing play, buckling sensitivity must be takein into account at choosing the raw material of bearings, or bearing sleeve.
In the advanced ceramics family, silicon nitride ceramic is an ideal choice to make ceramic sliding bearings or bearing sleeve because of their remarkable features, please find find the strength of this ceramic material from the table below:
| Property | Unit | Value | |
| Silicon nitride | Stainless steel | ||
| Coefficient of friction | 0.40 | 0.4 | |
| Density | g/cm3 | 3.3 | 7.5~8.0 |
| Water absorption | % | 0 | 0 |
| Hardness | HV | Over 1630 | 210 |
| Flexural strength | MPa | 900 | 938 |
| Compressive strength | MPa | 2500 | 22.9~57.6 |
