has a bi-layer structure of low carbon steel backing and copper alloy (CuSn6.5P0.1) sliding layer. This product is lead-free. To decrease abrasion, oil grooves can be formed on the surface of alloy. According to the requirement, the steel back can be plated with anticorrosive coating. bimetal bushings series products are often used as wrapped bushes, thrust washer and bushes on mainshaft and connecting rod of internal combustion engine.Steel backing can be copper plated Steel+CuSn6.5P0.1 Basic concept of composite bimetallic bearing
Bimetal bearing is one of the oil-free smooth bearings. The compound bearing is made of high quality low carbon steel back with sintered lead-tin bronze alloy on the outside.It has the characteristics of high bearing capacity, impact resistance, high temperature resistance, strong self-smoothness, etc., especially suitable for heavy load, low speed, reciprocating or rocking, etc., which is difficult to smooth and form oil film, and is not afraid of water flushing and other acid corrosion and erosion.
Because the substrate is stable for low carbon steel, so the machining accuracy of the outer diameter is guaranteed, and dry bearing in the product into the seat hole does not need screw fixation, relying on interference cooperation can avoid the phenomenon of going round.The modification of the chemical composition of inner surface alloy layer can satisfy the requirements of different bearing pressure, different operating temperature and different sliding speed.
Bimetal bearing has the advantages of good wear resistance, especially suitable for medium speed and low speed and high load.Through special technique, it can process various oil groove, oil hole and oil hole on the conflict surface, and then adapt to different smooth conditions.The products are mainly used in the balance bridge bushing and gasket of heavy duty vehicles.Automobile engine, chassis, motorcycle clutch, gear pump cleaning plate and lifting equipment and other categories.
JF800 Bimetallic Bearings Bushing Made in China JF800 bush,bimetal bush Introduction Bi-Metal bushing is composed of high quality low carbon steel and bronze with the characters of wear high speed, high load capacity, very compact dimensions, low wear.
Spilt bimetal bushings Product DescriptionJF800 / SAE797. JF800 Bimetallic Bearing's steel-bronze-compound material with indents as reservoir for the grease. JF800 Bimetallic Bearings has high load capacity, very good resistance to fatigue strength at higher temperatures. JF800 Bimetallic Bearings is applicable in rough operation conditions. JF800 Bimetallic Bearings
The product is made with high-quality low carbon steel plate as mitrix,the surface is sinterrd with lead green aliminum alloy,and it is made through many times of sintering and rolling.It has medium fatigue strength and good surface performance of bearing.The products are mainly used for connecting rod bearing of spindle on internal combustion engine.

Bimeatl Bushing Split Gap Design
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
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.
