7204 Ceramic Ball Bearings +PEEK Cage with P6/ABEC3-P4/ABEC7
Precision
Description of 7204 Ceramic Ball Bearings :
7204 ceramic ball bearings belongs to the ceramic angular contact
ball bearing series, 7204 ceramic ball bearings is mainly used in
compressors, eye drop machinery, transmission shaft, non-metallic
material testing machine, forging, casting machinery, packaging
mold, wind blades, leakage emergency, electronic and electrical
production lines, vehicle lights and other equipment.
Advantages and main properties of ceramic ball bearing:
(1) High temperature resistance
The ceramic ball is hot and the expansion coefficient is small. In
the high temperature environment, the bearing ball will not expand
because of the temperature, which greatly improves the use
temperature of the whole bearing. The temperature of the ordinary
bearing is about 160 degrees, and the ceramic ball can reach more
than 220 degrees.
(2) High speed
Ceramic ball has oil-free self-lubrication property, ceramic ball
friction coefficient is small, so ceramic ball bearing has a high
speed. According to statistics, the bearing with ceramic ball is
1.5 times more than the speed of the general bearing.
(3) Long life
The ceramic ball can not add any grease, that is to say, even if
the grease is dried, the bearing can still run, so as to avoid the
occurrence of premature bearing damage caused by grease in ordinary
bearings. According to the actual use data show that the service
life of the bearing after the use of ceramic ball is 2-3 times that
of ordinary bearings.
(4) Insulation
The last point is also the most important point - insulation, the
ceramic ball bearing, can make the bearing between the inner and
outer rings insulation, because the ceramic ball is an insulator,
in the bearing between the inner and outer rings with ceramic ball,
you can achieve the effect of insulation. This enables the bearing
to be used in an electrically conductive environment. The rolling
bearing is composed of a ring, a rolling body, a retainer, grease
and seals. When the rolling body is made of ceramic material, the
rolling bearing is defined as a ceramic ball bearing.

Application
Ceramic bearings can be widely used in aviation, aerospace,
navigation, petroleum, chemical, automotive, electronic equipment,
metallurgy, electric power, textile, pump, medical instruments,
scientific research and national defense and other fields, is the
application of new materials of high-tech products.
Application field:
Used in extremely harsh environment and special conditions, such as
chemical industry, fluid industry, smelting, food, electronics,
semiconductor, medical, vacuum, magnetic and other occasions.
Use
How to ensure that bearings work reliably?
Generally speaking, from the point of use, we should pay attention
to the following points:
1. Bearing clearance should be appropriate, too large impact, too
small lubrication is poor, may burn tile;
2. Bearing and journal surface quality and geometric shape should
be strictly guaranteed;
3. Improve lubrication quality, control oil pressure, temperature
and flow, strengthen oil filtration;
4. Use fuel oil and lubricating oil in accordance with the
regulations.
In order to give full play to bearings and maintain their due
performance for a long time, regular maintenance (regular
inspection) must be done effectively. Early detection of faults and
prevention of accidents through proper regular inspection are very
important for improving productivity and economy.
