Product Details

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 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.
Alloy layer material CuPb10Sn10 or CuSn6Zn6Pb3



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.


The products are applied to water conservancy and hydropower industry: hydraulic machinery: horizontal support slide of hydraulic steel gate, support bearing of hydraulic hoist and closure machine, sand blasting maintenance door bearing, etc.Hydraulic turbine: guide vane shaft sleeve (upper guide, middle guide, lower guide), wheel shaft sleeve, pin shaft sleeve (connecting rod pin, push and pull rod pin, relay piston pin), anti-wear ring plate (thrust ring), anti-wear block, control ring side tile.
Metallurgical industry: die-casting machine bearing, rolling cutting shears (bilateral shears, fixed length shears on the skateboard), etc.
Valve industry: butterfly valve, globe valve, etc.
Others: mining machinery, packaging machinery, construction machinery, heavy machinery, injection molding machine, automobile tire mold, wind turbine, thermal power and other industries.
