Self-lubricated oilless bearings with graphite insert washer are a
unique and innovative solution for various industrial applications.
These bearings are designed to operate without the need for
external lubrication, relying instead on the self-lubricating
properties of the graphite insert.
The graphite insert washer provides excellent lubrication and wear
resistance, enabling the bearing to operate smoothly and
efficiently even under high loads and speeds. The graphite material
has inherent lubricating properties that help reduce friction and
heat generation, thus enhancing the bearing's lifespan and
performance.
Furthermore, the oilless design eliminates the need for regular
lubrication and maintenance, reducing operational costs and
downtime. This makes these bearings particularly suitable for
applications where lubrication is difficult or impractical, such as
in dusty or wet environments.
Overall, self-lubricated oilless bearings with graphite insert
washer offer a reliable and cost-effective solution for industrial
applications that require smooth and efficient operation without
the need for external lubrication.

Metallic, self-lubricating bushings are made up of one of four basic compositions: Strong Cast Bronze, Bronze Bushings
Since bearings usually receive a lot of frictional resistance that
generates heat, lubricants such as oil or grease are used to
prevent the seizing or abnormal wear that this frictional heat
could otherwise cause. Lubrication-free bushings don't need
lubricating oil because the bearing body has a lubricating
structure made possible by lubricating oil in the bearing body, or
by embedded solid lubricant or the like. Since they don't need
lubricating oil, lubrication-free bushings are often used for
applications such as precision machinery that makes lubricating oil
refilling difficult, and equipment with poor affinity to oil. They
also greatly reduce maintenance costs by eliminating the need for
regular lubrication and enabling stable operation over long
periods. Lubrication-free bushings come in a variety of shapes that
can be used for different applications as needed. Examples include
straight bushings, collar bushings, flange bushings, and housing
bushings.
Our bearings have been developed for high load, low speed
applications and are made from rotationally cast high strength
bronze using a specially formed graphite plug as a lubricant.
Our range of oil free washers are available in metric and imperial
sizes. Our in-house machining service can produce non-standard
sizes to meet customer's specific needs.

Self-lubricating bearings and sliders embedded with solid
lubricants, under the action of friction heat, expand the solid
lubricant, automatically transfer to the friction surface, form a
layer of lubricating film to prevent metal-to-metal contact,
thereby reducing friction factor and wear, and improve The bearing
capacity of the bearing. Metal skeleton, according to the needs of
gear pump bearing users, bronze, cast iron, cast steel, stainless
steel, non-metallic skeleton can be used bakelite, phenolic
plastic, nylon and so on.
Second, the characteristics of inlaid bearings and sliders:
Self-lubricating bearings and sliders with solid lubricants are
made of 10 kinds of lubricating materials with excellent
lubricating properties and special lengths, some of which can
accept under heavy load. The bearing pressure is on the 2 um thick
JDB solid inlaid bearing film, the friction speed of 40m per second
can withstand the contact stress of 2800Mpa; some components, low
shear force between molecules, low adhesion is easy to form
Molecular slip surface, only in the lubrication layer of 2.5um
thickness, there are about 40,000 JDB bronze inlaid bearing slip
surface, which plays a key role in the lubrication performance of
solid lubricant; some components are at 399 °C high temperature,
The friction factor is normal; some components have good
lubrication properties in normal temperature, normal load, high
friction speed, vacuum, and atmosphere. In short, self-lubricating
solid lubricants with inlaid bearings and sliders can be adapted to
the friction conditions of various working conditions. The friction
factor is mostly between 0.006 and 0.09.
Third, the use of inlaid bearings, sliders: Inlaid bearings and
sliders are embedded in the skeleton by solid lubricants,
self-lubricating friction operation, ideally solve the pollution
problems caused by liquid lubricants in the lubrication process, so
Widely used in food machinery and other non-polluting environments.
The solid lubricant used in the inlaid bearing and the slider has
the characteristics of large load bearing, so it is very suitable
for the heavy-duty, low-speed, high-temperature, water vapor and
other corrosion conditions and the inconvenient and frequently
lubricated working conditions of the oil film. Used in mining,
metallurgy, petroleum, geology, chemical, paper, bridges, hydraulic
hubs, ships, and other industrial sectors. The most outstanding
results, such as steel ladle cranes and 1150 roughing mills, are
6-8 times longer than the original bearing pads. Various rolling
mills, shearing machines, cold bed sliders (pipe pullers), twisting
pots, rubber mill bearings, floating crane bearings, textile mill
dryers, non-ferrous metal rolling mills, steel plates for
heavy-duty vehicles The pin bushing, the twisting mixer of the
chemical plant, the roller bearing of the coal mine conveyor, the
inner sleeve of the drilling machine deep rod pump, the protective
drill sleeve and the guiding bushings, sliders and cam discs on
various equipments are all very obvious. .
Fourth, the use of inlaid bearings, sliders:
(1) Inlaid bearings and sliders have been coated with a special
layer of grease on the friction surface before leaving the factory.
Do not soil the friction table during installation. Do not wipe off
the grease! ! ! If it is rubbed off, please replace it with
molybdenum disulfide lithium grease, but it must be run at low
speed for a period of time before the test run, in order to operate
normally. When using heavy load equipment, you must purchase
special grease repaint from the seller. .
(2) When installing the inlaid bearing, it must ensure a certain
sliding clearance to prevent jamming and damage the bearing and the
machine.
(3) When installing the inlaid bearing, it should ensure that the
shaft diameter with which it is rubbed has a good cylindricity, so
that it has sufficient contact area with the bearing, otherwise it
will seriously affect the service life of the bearing or damage
immediately.
Five, inlaid bearings, sliders factory specifications: This product
is widely used in many industries, so it is difficult to unify
specifications.
