Bronze bearing & bushings for agricultural machinery, conveying
installations and construction machinery
C86300 Centrifugal Casting Copper Alloy Bronze Bush Bearings Highly
Wear Resistance
Solid lubricated bearings (JDB) have at least the following
advantages:
These bearings are mainly used in agricultural machinery, conveying
installations and construction machinery.

Bronze Bearings Solid Bronze Lubrication | VSB-50
This type of bearing is suitable for middle or low speed with heavy
load condition. It is widely used for engineering machinery,
vehicle, steel and iron and takeup machinery.
1. Flexible, simple and convenient design, wide range of use:
Fuel supply system in the engineering design is a piece of work,
time-consuming setup, using solid lubrication bearings do not need
to consider when designing refueling device, save the refueling
devices, as well as for a wide variety of special occasions, the
solid lubricated bearing design into various shapes, in order to
satisfy various occasions, the use of solid lubrication bearing,
can greatly reduce the mechanical maintenance, oil and other
expenses.
2. Low use cost:
The traditional mechanical design, in a certain operating time,
want to often come on maintenance, check the oil, the oil supply
device was clear, the body itself and the surrounding environment
pollution caused by regular gas, result in an increase in
maintenance costs, realize self-lubrication, not only can realize
the environment clean and tidy, and greatly reduce the cost of the
use of lubricating oil.
3. Oil free:
Due to the linear expansion coefficient of solid lubricant is
greater than the metal matrix, so when the solid lubricated
bearing, when we started running on the oil film will shift to a
grinding and realize self-lubrication, so solid lubrication
bearings can be used in the place where is hard to go and can't go
or grease, even in the case of low speed and high load, also can
have good lubrication effect.
4. Under the condition of high load bearing and low speed, it can
give play to superior performance:
Solid lubricated bearing is a centrifugal casting of high strength
brass as the matrix, play the role of load bearing, with a good
self-lubricating performance of the special formula of graphite as
a lubricant, play the role of self-lubricating, so it combines
their own advantages, even in the case of high load, low speed, can
play a superior performance.
5. Excellent resistance and corrosion resistance:
The lubricant of the solid lubrication bearing is made of special
formula graphite, PTEE and other wear-resistant materials, it has a
stable molecular structure, the metal matrix can be selected
according to different metals have different resistance and
corrosion resistance, so the solid lubrication bearing has
excellent resistance and corrosion resistance.
6. In places where oil film formation is difficult, such as
reciprocating movement, swing movement, frequent starting and
stopping, excellent wear resistance can be exerted:
The arrangement principle of the lubricants of the solid
lubrication bearing is to ensure that there are lubricants on all
parts of the grinding parts in the running process. Therefore, the
arrangement position of the lubricants must be determined according
to the movement direction of the grinding parts.
7. Long working life, little maintenance, long replacement cycle
and good performance.
Due to the requirements of special production process, some key
equipment of industrial and mining enterprises operate under
extremely bad working conditions.Due to heavy equipment, high
ambient temperature, large dust or acid corrosive gas CO, SO2 in
the air, the lubrication of the equipment brings a lot of problems,
serious friction and wear, in order to produce continuous
operation, in addition to the original design requires the
installation of multiple equipment wheel repair, also need to
invest a lot of maintenance personnel.It seriously restricts the
improvement of productivity, and the consumption of spare parts and
energy is extremely large, which has become an important obstacle
to the development of production.

free maintenance etc, has successfully supporting several world
famous manufacturers of injection molding machine, die-casting

Cost efficiency
The traditional mechanical designing requires frequent oiling
maintenance; oil gauge check shall be performed to ensure the
passage of oil supplying apparatus is clear. Since the periodical
oiling can cause pollution to the machines themselves as welI as to
the ambient surroundings, resulting in an increase of the
maintenance cost,the realization of self-lubrication can not only
make the environment clean but greatly reduce the Iubricating costs
as well.
