Bimetal bushings for track rollers refer to bushings that are made
of two different metals, usually combined through a special
manufacturing process. This combination of metals offers unique
advantages, such as improved wear resistance, higher load-bearing
capacity, and better heat dissipation. The outer layer of the
bushing is typically made of a harder, more wear-resistant metal,
while the inner layer provides better lubrication and corrosion
resistance.
Bimetal bushings for track rollers are widely used in various
industrial applications, including conveyor systems, material
handling equipment, and heavy machinery. They are designed to
provide smooth and reliable operation under high loads and
challenging conditions. The bimetallic construction ensures
durability and longevity, reducing the need for frequent
maintenance and replacement.
The use of bimetal bushings for track rollers helps improve the
efficiency and performance of machinery and equipment, reducing
downtime and operational costs. They are an essential component in
ensuring the smooth and efficient operation of industrial systems.

Bimetal bearings are able to handle heavy loads and shock loading
conditions. Our bimetal bearings have anti-corrosion capabilities
and are easy to install, making them ideal for emergency
replacements.
Friction welding bimetal bearing bushing made in china has been
widely used in the site of all kinds of construction machinery,
such as the supporting wheel, guiding wheel and supporting sprocket
wheel of bulldozer, excavator, transporter, etc.
It is an important part in construction machinery. It is made of
bimetal rolling bearing and bimetal gasket through friction melting
welding.The product USES copper alloy in the contact sliding part
of the shaft, which can play a good role in lubrication and
protection of the shaft and shaft shoulder when used. The back
lining USES steel, which has a stronger bearing capacity and
further reduces the material cost.
The product can bear axial and radial load at the same time when it
is used. It is suitable for the rotating and swinging of medium and low speed and high load.

Bimetal Bearings JF800 Bimetal bushing Size and Tolerance
VIIPLUS offers a broad range of sizes, forms and materials in
monometallic and bimetallic bearings. Bimetal and metal bearings
offer excellent corrosion resistance in industrial outdoor applications and in water, marine and
offshore environments. VIIPLUS bearings can be made in many sizes and forms, including thin-walled,
thick-walled, flanged, cylindrical, sintered and oil-impregnated,
and more. Some popular bearing materials and their benefits
include:
Bimetal bearings are able to handle heavy loads and shock loading
conditions. Our bimetal bearings have anti-corrosion capabilities
and are easy to install, making them ideal for emergency
replacements. VIIPLUS( JF800 )bearing is available with stainless steel, carbon steel or bronze backing.
Because the matrix is stable as low carbon steel material, so the machining accuracy of the outer diameter of the shaft
sleeve has been guaranteed, and there is no need for screw fixation
after the product is loaded into the seat hole, relying on
interference fit can prevent the phenomenon of going out of the
circle.The change of chemical composition of inner surface alloy
layer can meet the requirements of different bearing pressure,
different service temperature and different sliding speed. The oil
groove and oil hole with different structure are designed in the
production of friction surface to meet the requirements of
different ways of oil adding, prevent shaft biting and adapt to
different lubrication conditions.
Widely used in automobile engine, motorcycle clutch, light
industrial machinery, construction machinery.
