Properties of Silicion Nitride Ceramic Shaft Sleeve

1. Silicon nitride shaft sleeve has high mechanical strength, good toughness and wear resistance, which can provide support and protection for the shaft to avoid direct wear and failure of the shaft.

2. Silicon nitride sleeve has high temperature resistance, good corrosion resistance, it can separate shaft and bearing, to avoid bearing direct contact with high temperature environment or corrosive media.

3. Silicon nitride ceramic sleeve has self-lubrication, low noise, easy assembly, can be used for occasions that can not be lubricated or lubricated more difficult, such as vacuum, high temperature and other environments.

4. Silicon nitride sleeve has high thermal conductivity, small thermal expansion coefficient, also with large elastic modulus, so the deformation under high temperature or heavy load is very small, which is conductive to high precision operation.

Applications of Si₃N₄ Shaft Sleeve

Silicon nitride sleeve is installed between bearing and shaft, which can provide support for the shaft, prevent wear of the shaft, reduce friction between the shaft and the bearing so to reduce the operating resistance and extend service life of the equipment.

It is widely used in machinery manufacturing, aerospace, automobile manufacturing and medical equipment and other industries.
