JF20 High Percentage Aluminum Alloy AISn20Cu Bushings Bitemal Bearings ​

 

 

JF-20 is a bearing with a high percentage of tin and aluminum composition.With stecl as back and press AISn20Cu as lining.the bushing is of fairly good performance in anti-fatigue, load capacity,anti-corrosion and smooth sliding movement.It is widely applied under high speed and low load.It can be made into bearing shells for internal combustion engine with mid or low power or bearing shells for trains,air compressor and coling machines.It is a good substitution for Babbit material.

 

Sliding layer can be machined with lubricating grooves and/or with grease indents

Aluminum-tin alloy for hydrodynam-ic applications

Steel+AlSn20Cu

 

JF-20 high percentage of tin with aluminum alloy bushing is backing on low carbon steel, pressed with AISn20Cu as liner. It has fairly good performance in anti-fatigue and good load capacity, anti-corrosion and smooth sliding movement.
It usually used as engine bearing with middle or low power, air compressor bushing. It is a good substitution for Babbit material.

Other Bimetal Boundary Lubrication Bearings

 

1. It is a steel and copper alloy product with low carbon steel plate as the matrix material and surface sintered CuPb10Sn10 or CuSn6Zn6Pb3 material. The product is a kind of balance bridge bushing and gasket for heavy duty vehicles with the strongest bearing capacity among the double alloy bearings.The slave wheel of a bulldozer;Automotive steel bushing, all used in this product. It is a widely used high - load low - speed sliding bearing.

 

2. The product is made of CuPb24Sn4 alloy sintered on the surface of a steel plate.The product has good anti-fatigue strength and bearing capacity.Suitable for medium speed medium load.There are occasions for oil sliding.When the surface is plated with soft alloy, it can be used as bearing and connecting rod bushing for high speed internal combustion engine to achieve good wear resistance and fatigue resistance.

 

3. The product is made of CuPb30 material sintered on the surface with steel plate as the matrix.Due to the high lead content, the product has good bite resistance and foreign body embedding.If the working surface is plated with soft alloy material, it can be used as high speed, medium and low load internal combustion engine spindle, connecting rod bushing, rocker arm bushing;Oil mercury side friction sheet.

 

4. Lead-free bimetal bearing, is an environmentally friendly bimetal bearing, it is based on low carbon steel plate as the matrix, the surface of the sintered CuSn6.5P0.1 steel copper alloy products.The product has high fatigue strength and bearing capacity, good sliding performance, in many cases can replace the lead bimetal bearing or copper sleeve.
