The flange oilless sleeve bushing with graphite die bearings is a
specialized component designed to provide exceptional wear
resistance and self-lubricating properties in various industrial
applications. These bushings are typically used in high-load and
high-speed rotating equipment, such as presses, punches, and other
die mold machinery.
The key feature of this bushing is the graphite die bearing
material. Graphite is an excellent choice for bearing applications
due to its low coefficient of friction and high thermal
conductivity. This allows the bushing to operate smoothly and
efficiently, even under extreme operating conditions.
The flanged design of the bushing provides additional stability and
support, ensuring a secure fit within the machinery. The
sleeve-type construction allows for easy installation and removal,
making maintenance and replacement a breeze.
The oilless design of this bushing eliminates the need for regular
lubrication, significantly reducing downtime and maintenance costs.
This is especially beneficial in applications where lubrication may
be difficult or undesirable.
The combination of the graphite die bearing material and the flange
oilless sleeve bushing design offers a robust and reliable solution
for various industrial applications. These bushings are well-suited
for high-performance and demanding environments, where precision
and durability are paramount.
In summary, the flange oilless sleeve bushing with graphite die
bearings is a specialized component designed to provide exceptional
wear resistance, self-lubricating properties, and stability in
various industrial applications. Its oilless design and graphite
bearing material ensure smooth and efficient operation, even under
extreme conditions.
The first cost-competitive alternative to C93200 (SAE660) bronze
bearings.
Owing to the high quality and variability, our oilless bushes are
widely used in the automobile, engineering, electrical and consumer
goods industries. Quality is the number one characteristic, which
our business partners expect from our sliding bearings products. We
endeavor to offer more – customer care, technical service, and
guidance – which our business partners receive tog with
high-quality materials for injection molding.
Oilless solid lubricant embedded bushing is made from strong
material and homogeneously embedded with solid lubricant in its
body.
It breaks through the limit of general bearing whose lubrication
depends on an oil film.
So it is suitable for high temperature, heavy-duty, anti-corrosion,
or where oil is hard to be introduced.
It′s performance doubles both on hardness and wear-friction. It is
now widely applied in successive Casting Machines,

Typically there are 3 Standard Types of Bushings:
Sleeve Bearing
Flange Bearing (Double Flange bushing also)
Thrust Bearing (also called a Thrust Washer)
Each type is available as a Plain Bearing, Grooved (Oil or Grease),
and/or Graphite Plugged Bearing.

bearing, and mating surface materials. Graphite plugs bronze
bearings should never be used where electrolytic corrosion can
occur, such as high humidity atmospheres or submerged equipment. In this case, -based plugs are recommended
Oilless Flange Sleeve Bearing Bushing High hardness impregnated brass solid lubrication bearing is improved upon
Oilless Flange Sleeve Bearing Bushing by further enhance the
hardness of high hardness brass, giving rise to higher load-bearing capacity and better wear-resistant property. The products are widely used in continuous casting
rolling machines, mining equipment, engineering equipment,
injection-molding machines, etc. Because of its high hardness, it's
difficult to machining and finish, it's recommended only for really
high load applications.

Material Features
Oilless Flange Sleeve Bearing Bushing, JDB material is made of
strong cast bronze based metal with special solid lubricants
embedded. The base metal withstands high load and the solid
lubricants provide for self-lubrication. Oilless Flange Sleeve
Bearing Bushing shows excellent performance without pre-lubrication under conditions of extreme high/lower
temperature with low speed. This material provides a maintenance-free bearing solution, particularly for high load, intermittent oscillating motion.
Oilless Flange Sleeve Bearing Bushing can be applied under dry, high temperature, high pressure, corrosive, water, or other chemical environments when no oil can
be introduced.
Oilless Flange Sleeve Bearing Bushing is widely be used in
automotive product line, water engineering, dam gate, plastic
industries, successive casting machines, steel rollers in
metallurgy industry, mineral machines, ship turbo generators,
hydraulic turbines, and injection molding machines.

Oilless Flange Sleeve Bearing Bushing fixing method
When pressing the oil-free bushing, use a vise or punch to press it
in quietly. In order to facilitate the press-in, it is recommended
to chamfer the end of the inner diameter of the fixed seat, apply a
small amount of lubricating oil to the inner diameter of the fixed
seat and the outer diameter of the bushing.
Anti-rotation screw/bonding
Note that when the oil-free bushing is prevented from falling off
and turning, it is recommended to use the following methods
depending on the conditions of use and the environment.
The life of oilless bushings depends on the amount of wear. The
calculation of wear amount is very different due to surface
pressure, sliding speed, movement pattern, lubrication conditions,
the surface roughness of the matching shaft, and other conditions.
From the viewpoint that the wear amount is proportional to the load
and sliding distance, the following formula is usually used to
calculate the wear amount. Please consider it as the standard for
selection.
Estimate wear(mm)W=K*1×p×v×T
Wear ratio(k):mm/(N/mm2·m/s·Hr)
Design surface pressure(p):N/mm2
Sliding speed(v):m/s
Friction time(T):Hr-hr
