Product Description

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.


Professional bimetal bearing supplier

bimetal bushings for track roller



Low price,Hight Quality Bimetal bearings can be made in many sizes and forms, including thin-walled, thick-walled, flanged, cylindrical, sintered and oil-impregnated, and more. The Bimetal internal surface of bronze can be channelled with different types of channels depending on and conditions of lubrication in which the bushes can be used.



Bimetal bushing is based on steel and sintered with CuPb10Sn10 or CuSn6Zn6Pb3 as a lining layer.

The strongest type of bimetal bushings and widely applicated in so many fields. This type has the best performance within the range of Cu-Pb alloy construcured bushing. Therefor it has a wide application and is mostly suitable for where is middle speed and high impact 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.
Alloy layer material CuPb10Sn10 or CuSn6Zn6Pb3



Typical Characteristics

Suitable for low speed, heavy load or intermittent movement conditions, lubricating oil film can not form or maintain the occasion;

Suitable for working environment or mechanical structure restrictions, it is difficult to supply oil lubrication occasions;
It is suitable for rotating, reciprocating, swinging, linear and other forms of movement, as well as occasions requiring frequent starting or starting under high load;

Suitable for high or low temperature work, or the environment temperature range of large occasions;Good corrosion resistance, can be used in seawater and other corrosive media such as chemical liquids or gases, as well as water containing sediment or radioactive environment;

Non-water absorption, good dimensional stability, high mechanical strength, good thermal conductivity;
Bearing is thin wall structure, light weight, small volume, suitable for compact design;
Compared with the traditional three-layer composite material, the static load characteristics, wear-resistance, service temperature, dimensional stability and so on under the condition of non-grease lubrication are better;
Compared with copper inlaid self-lubricating material, it is more suitable to work under the condition of small Angle swing, and the price is cheaper.
