Silicon nitride ceramic bearings self-lubrication high precision non conducting insulation waterproof
product name:Silicon nitride ceramic bearings
Compared with traditional steel bearings, the specific advantages
of silicon nitride ceramic ball bearings are as follows :
High-speed operation performance. During the use of the bearing,
with the increase of the rotational speed, the centrifugal force
generated by the bearing operation increases greatly, resulting in
an increase in the sliding friction between the bearing ring and
the internal roller, resulting in a skidding phenomenon of the
bearing, which ultimately leads to a shortened service life of the
bearing. Due to the low density of the ceramic ball bearing, the
centrifugal force of the internal ceramic ball during the rotation
process is greatly reduced, and the slip phenomenon caused by the
centrifugal force is also greatly reduced, thus improving the life
of the bearing.
Good friction performance. In a high temperature working
environment, even if the lubrication fails, the friction
coefficient of the ceramic bearing is small, the temperature rises
slowly after the lubrication failure, the volume expansion is
smaller, it is not easy to jam the bearing and prolong the service
life of the bearing.
High temperature performance. When the temperature is high, the
strength of ceramic ball bearing will not be greatly reduced at
high temperature compared with steel bearing, which has good high
temperature performance.
Chemical stability. Compared with traditional bearing steel,
silicon nitride ceramic material has excellent chemical stability
in common strong acid and alkali environment, and it is difficult
to be corroded by strong acid such as sulfuric acid, hydrochloric
acid and strong alkali such as sodium hydroxide. In addition,
compared with steel bearings, ceramic bearings do not have
electrical conductivity and magnetism, so it is safer to use
ceramic bearings in a strong magnetic environment.
