The bimetal washer embedded with graphite plugs is a unique
mechanical component that combines the strength and durability of
two different metals with the lubricity and wear resistance of
graphite. This innovative design ensures optimal performance in
applications requiring high precision, reliability, and extended
service life.
The bimetal washer itself consists of two layers of metal,
typically chosen for their specific material properties. One layer
may be selected for its strength and durability, while the other
layer may be chosen for its corrosion resistance or other desired
properties. The combination of these two metals allows the bimetal
washer to perform optimally in a wide range of environments and
applications.
Embedded within the bimetal washer are graphite plugs. Graphite is
a natural form of carbon that exhibits excellent lubricity,
self-lubricating properties, and wear resistance. When graphite is
embedded in the bimetal washer, it provides a continuous
lubrication source that reduces friction and wear between moving
parts. This results in smoother operation, less wear, and longer
service life for the mechanical system.
The graphite plugs are strategically positioned within the bimetal
washer to maximize their effectiveness. They are typically embedded
in high-wear areas or in areas where friction is a concern. The
size, shape, and number of graphite plugs can be customized based
on the specific requirements of the application.
The bimetal washer embedded with graphite plugs is commonly used in
automotive, aerospace, and industrial machinery applications. Its
ability to provide continuous lubrication and wear resistance
ensures smooth and reliable operation of moving parts, even under
extreme conditions. This innovative design represents a significant
improvement over traditional metal washers, offering superior
performance and durability in demanding applications.
Bimetal Washer Embedded Graphite Plugs-08G is a kind of steelhead
bronze alloys-based bearing that is embedded with a particular
formulation of solid lubricants. Owing to the high strength, high
load capacity, and the spirally distributed diamond embedded with
solid lubricant. With a lubrication area of 25% on the bearing
surface up to,, the bushing shows better performance in good
lubrication and anti-wear. This type of bearing is particularly
applied in gearbox for automobiles, generators, cranes, and
machines for the metallurgical industry.
