● ●Definition:
Full ceramic bearing refers to the inner ring, outer ring, rolling element is a ceramic material bearing.
● ●Material:
Zirconia full ceramic bearings, silicon nitride full ceramic bearings, silicon carbide full ceramic bearings and alumina full ceramic bearings.
● ●Accuracy:
P0~P5。
● ●Size range:
Minimum inner diameter 3mm, maximum outer diameter 200mm.
● ●Model:
Can produce 350 models, covering a variety of metric and inch deep groove ball bearings, self-aligning ball bearings, angular contact bearings, plane bearings, spherical bearings. Can provide open, sealing ring form, dust cover form and other structures.
We can design and produce corresponding non-standard bearings according to the working conditions provided by customers.
Cage: nylon (NYLON), polytetrafluoroethylene (PTFE), polyetheretherketone (PEEK), stainless steel, copper or full ball.
● ●Performance advantages:
The advantages of full ceramic bearings compared to steel bearings are:
1, can be used for higher temperatures: ceramic materials at high temperatures can maintain its mechanical properties, so it can be used in high temperature fields.
2. More suitable for temperature changes: Since the thermal expansion coefficient of ceramics is smaller than that of steel, the clearance of ceramic bearings is less affected by temperature changes than steel bearings, so that they can be used in a wider range of temperature fluctuations.
3. Better anti-seizure and anti-seizure performance: This is because the thermal expansion coefficient of ceramics is smaller than that of steel, which helps to reduce thermal deformation and improve anti-seizure ability.
4. It can work without oil: ceramic has self-lubricating characteristics and can also be lubricated by medium, so it can be applied to high vacuum and inconvenient lubrication.
5, acid, alkali, salt corrosion, so it can be used in chemical corrosion occasions.
6. It can be used in occasions that require electrical insulation and no static electricity: the ceramics produced by our company are non-conductive, non-static, and will not produce current ablation of steel bearings.
7. Can be used in magnetic environment: ceramic is non-magnetic, magnetic foreign matter or abrasive particles are not easy to adhere to the channel, which can reduce abrasive wear.
● ●Application areas:
For extremely harsh environment and special conditions, such as chemical industry, fluid industry, smelting, food, electronics, semiconductor, medical, vacuum, magnetic and other occasions.
● ●Note:
1. The thermal expansion coefficient of ceramic materials, especially silicon nitride, silicon carbide and alumina, is much smaller than that of steel. Therefore, if it is not handled properly, the full ceramic bearing is likely to be broken due to the different expansion coefficients of the materials when it is matched with the steel shaft.
2. Full ceramic bearings are not suitable for heavy loads and variable loads.
