The self-lubricating oilless flanged graphite bronze sleeve bushing
is a specialized mechanical component designed to provide smooth
and reliable operation without the need for external lubrication.
This type of bushing is crafted from graphite bronze, a material
that combines the benefits of both graphite and bronze, resulting
in exceptional wear resistance, corrosion resistance, and
self-lubricating properties.
The flanged design of the bushing allows for easy installation and
secure attachment to machinery components. The graphite bronze
material is inherently self-lubricating, meaning it can maintain a
low coefficient of friction and reduce wear even in the absence of
external lubricants. This eliminates the need for regular
lubrication maintenance, reducing downtime and improving overall
system efficiency.
The self-lubricating oilless flanged graphite bronze sleeve bushing
is ideal for applications where lubrication is difficult or
undesirable, such as in high-temperature or high-pressure
environments. It is also suitable for applications involving
frequent start-stops, high-speed rotation, or heavy loads, as it
can maintain a consistent level of performance even under extreme
operating conditions.
In summary, the self-lubricating oilless flanged graphite bronze
sleeve bushing is a reliable and efficient solution for reducing
friction and wear in mechanical systems. Its unique combination of
material properties and design features enables it to operate
smoothly without the need for external lubrication, improving
system performance and reducing maintenance requirements.
These oilless bushings are self-lubricating bearings composed of
high strength brass alloy bases manufactured with advanced casting
technology and built-in solid lubricants. They can be combined with
different types of solid lubricants depending on the conditions of
use.

Solid graphite plugged bronze oilless bushings
The base of the solid lubricating bearing should be determined
according to the working conditions of the bearing itself. The more
commonly used materials are high-strength brass, tin bronze, castings, etc. There are two main types of
embedded solid lubricating materials, one is natural black lead,
Artificial graphite is synthesized with MoS2, and the other is
synthesized with . According to the bearing's own working
conditions, through the combination of different metal substrates
and embedded solid lubricants, it can ensure that the product can
meet various temperatures, loads, motions and media. Special needs
under the conditions, while ensuring stable and reliable work.
JDB solid graphite plugged bronze bushings
JDB solid graphite plugged bronze bushings are widely used in
metallurgical continuous casters, train supports, rolling
equipment, mining machinery, ships, steam turbines, and other high
temperature, high load, low speed and heavy load occasions; in low
load, high temperature, medium speed and other occasions, such as
fireplaces Door, oven raceway, rubber machinery, light industry
machinery, machine tool industry; its end face can be welded and
installed with the base body, so it is suitable for metallurgical
machinery, construction machinery, oil transportation machinery and
other fields that cannot be refueled; in lifting machinery The
supporting parts are especially adapted, such as hoist support,
crane support, and excavator support.
Application characteristics of oilless bushing:
It is especially suitable for rotating motion under heavy load and low speed, rocking motion and parts that are not easy to form fluid
lubrication under load; it can be used for a long time under
boundary lubrication conditions without refueling maintenance, and
refueling in the process can make the bearing use The service life
can be more extended; the plastic layer on the surface can leave a
certain margin during the forming and processing of the shaft
sleeve, and can be processed by itself after being pressed into the
opening to achieve a better assembly size.
At present, it is mainly used in metallurgical machinery, mining
machinery, water conservancy machinery, automobile chassis,
construction machinery, agricultural machinery, steel rolling
machinery, etc.
1. The mixture of modified polyoxymethylene (POM) and lead is 0.3~0.5mm, which has high wear resistance, and has a
low friction coefficient even in the case of instantaneous oil
shortage. There are regularly arranged oil storage pits with spiral
angles on the bearing surface, which must be covered with
lubricating grease during assembly.
2. The copper powder layer is 0.2~0.3mm, which has good carrying capacity and wear resistance, and good thermal conductivity can transfer the heat generated
during the operation of the bearing in time. The composite material
can penetrate into the gap of the copper powder ball to improve the
bonding strength.
3. Low carbon steel 0.4~2.2mm, improve the bearing capacity and
heat transfer effect.
4. Copper/tin plating layer, copper plating layer 0.008mm, tin
plating layer 0.005mm, so that the bearing has good corrosion
resistance.
