Material CuPb30 SAE48 JF700 BiMetal Bushings Plain Bearing for Agricultural Machines are specialized components designed to meet the demanding requirements of agricultural machinery applications. These bushings feature a bimetal construction, combining the outer layer of steel or iron alloy with an inner layer of CuPb30 (a lead-tin bronze alloy) for superior wear resistance and load-bearing capabilities.

The CuPb30 alloy, which is also known as SAE48 or JF700, is chosen for its excellent lubricity, corrosion resistance, and ability to withstand heavy loads and high speeds. This alloy composition ensures that the bushings can function effectively in harsh agricultural environments, where dirt, dust, and moisture are common.

The bimetal design of these bushings allows for a strong outer shell that can support the loads and stresses encountered in agricultural machinery, while the CuPb30 inner layer provides the necessary wear resistance and lubricity to reduce friction and wear. This combination of materials and design ensures that the bushings can last longer and require less frequent maintenance or replacement.

The plain bearing design of these bushings means that they do not require any additional lubrication, simplifying installation and maintenance. They can be pressed or fitted directly into the machinery's components, providing a reliable and low-friction interface for rotating parts.

In summary, Material CuPb30 SAE48 JF700 BiMetal Bushings Plain Bearing for Agricultural Machines are designed to meet the demanding requirements of agricultural applications. Their bimetal construction and CuPb30 alloy composition provide superior wear resistance, load-bearing capabilities, and lubricity, ensuring smooth and reliable operation of agricultural machinery.

JF-700Bimetal Metal Bushing

Jf-700 bimetallic bearing, is a steel plate as the matrix, the surface sintered CuPb30 material products, the product because of high lead content, so has a good anti-bite shaft and different physical buried.If the working surface is plated with soft alloy material, it can be used as the spindle bush, connecting rod bushing and rocker arm bushing of internal combustion engine with high speed and low load.Friction disc on pump side.
 
 

Introduction:
 

Bimetal bearings are steel shell backed with a lead bronze lining bearing material for oil lubricated applications. This material has high load capacity and good fatigue properties.
Bimetal Layers
1. Sinter bronze powder: Good wear resistance and excellent load carrying capacity.
2. Steel backing: Provides exceptionally high load carrying capacity, excellent heat dissipation.
3. Copper plating thickness 0.002mm provides good corrosion resistance.

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.

Range Of Application

 
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.
This product is the most powerful bearing capacity in the double-alloy bearing, the balance bridge bushing and gasket of heavy vehicles;Driven wheel and supporting wheel of bulldozer;Automobile steel plate bushing, Uses this product.It is a kind of high load and low speed sliding bearing widely used.
 

Agricultural Machinery

 
As the self-lubricating bearing has the characteristics of maintenance-free and good abrasion resistance under dust and outdoor conditions, it is widely used in the cylinder, suspension system of combine harvester, planter, baler, crusher, tractor, Joints and other parts can not be difficult to form oil or oil film parts.
