Bronze Graphite Plugged Bushings of the Straight Flanged Type are
bushings made from bronze alloys that are reinforced with graphite
particles. The graphite addition enhances the self-lubricating
properties of the bronze, resulting in smoother operation and
reduced friction. The straight flanged design provides a secure
attachment to mechanical components, ensuring stability and
durability during operation.
These bushings are commonly used in high-load and high-speed
applications, where they can effectively reduce wear and extend the
service life of mechanical systems. Their use is widespread in
various industries, including machinery, automobiles, and heavy
equipment, where reliable and durable bushings are crucial for
optimal performance.
Material Graphite Filled Bronze Plate Bushing
Utilizing its extensive problem-solving capabilities and experience
with self-lubricating bearings, it offers a solution to a
long-standing problem for mines and quarries. Many conveyors
operating in harsh mine environments have the problem of premature
self-lubricating bronze bushing bearing failure on head, tail,
transmission, and tensioning wheels. There are many reasons why use

Product Description
Our present position in the industry is chiefly attributable to our
specifically designed Graphite Bronze Split Bush from our exclusive collection of products
Graphite bronze bearings are a substrate of carbon steel, bronze
powder, , fiber and other materials through a special process to
produce self-lubricating products, with the characteristics of
environmental protection
The solid inlaid bearing is on a brass matrix.A high performance
solid lubricant inlaid with graphite or MoS2 solid lubricant.It
breaks through the limitation that the general Graphite Bronze Bearings depends on oil film lubrication.In the process of use, the
friction heat makes solid lubrication and shaft friction, forming
an excellent condition for oil and powder to coexist lubrication,
which not only protects shaft from wear, but also makes solid
lubrication characteristics eternal.Its hardness is twice as high
as that of ordinary copper sheath, and its wear resistance is also
twice as high.At present, the Graphite Bronze Bearings product has been used in metallurgy continuous casting machine,
train support, steel rolling equipment, mining machinery, ships,
gas turbines and other high temperature, high load, low speed heavy
load and other occasions.

Description
Graphite Bronze Bearing-Imperial line bushings (dimensions in
inches)
Graphite Bronze Bearing are metal backed with bronze alloy graphite
oil-less bushings.
These are multi-layer composite bearings made of a special sintered
material used as sliding surfaces and a steel material as a support
metal. The sintered layers are made of a special copper-nickel
alloy containing a uniformly dispersed solid lubricant, the main
component of which is graphite. Solid lubricants will be released
to the surface of the ring as they wear, which will ensure a lower
coefficient of friction during operation. In addition, these
sintered layers were treated by the oil impregnation treatment.
Features
1．no oil supply device, oil hole, oil groove
The cost of the fuel supply system, the cost of processing,
assembling, and so on, can greatly reduce the cost of
manufacturing.
2．Operation cost reduction
Greatly reduce the use of lubricating oil and equipment maintenance
costs, but also exempt from the risk caused by the shortage of oil.
3．design time shortened
No oil can make the design, structure is greatly simplified, reduce
costs, save design time. In addition, using self-lubricating
bearings can also improve the mechanical properties and prolong get
remarkable results using life and improve the reliability.
4．recovery and environmental protection of lubricant
No need to waste oil recycling, is conducive to environmental
protection.
Use notes
1．In the possible case, the design uses the standard specification
as far as possible;
2．Please note that there is no foreign body in the assembly;
3．After using the sliding surface, formed by solid lubricant oil
film in surface with black or gray black phenomenon, please do not
scrub, as usual.
4．Before the assembly, if the lubricating oil applied to the
grinding parts, can shorten the running in period, conducive to the
operation of machinery, operation;
5．When the assembly should be slowly pressed into, it is strictly
forbidden to beat, so as to avoid damage to the Graphite Bronze Bearings and deformation;
6．Design, different parts should be selected with appropriate
material, in order to improve the mechanical performance, to extend
the service life of the Graphite Bronze Bearings;
7．In the high load, reciprocating motion, the proposed use of screw
fixation;
8．In fresh water, sea water and in the sea, on the use of stainless
steel or surface plating.
Characteristic
1. Flexible, simple, convenient design with wide applications
2. FunctionaI in absence of oiI
3. Cost efficiency
4. Excellent performance under high load and low speed
circumstances
5. In circumstances where it is difficult to generate hi-films,
such as reciprocating movements, rotating movements and frequent
on-off, Graphite Bronze Bearings highlights its excellent abrasion resistance.
6. Excellent chemical resistance and corrosion resistance
