Jf800 Gunmetal Bronze Bimetal Bearing Bushes Groove Design
JF800 Gunmetal Bronze Bimetal Bearing Bushes with Groove Design refer to bushings made of a bimetallic material combining gunmetal (a type of bronze alloy) and another metal, typically steel. The groove design is a specific feature that allows for lubrication or the retention of lubricant, enhancing the bushing's performance and durability.
Gunmetal bronze is chosen for its excellent wear resistance, corrosion resistance, and load-bearing capacity. The bimetallic construction provides a strong and durable backing material, while the gunmetal layer ensures smooth operation and reduced friction.
These bushings are widely used in various industrial applications where high-performance and long-lasting bearings are required. The groove design makes them particularly suitable for applications where lubrication is critical, such as in rotating machinery, engines, and pumps. The use of JF800 Gunmetal Bronze Bimetal Bearing Bushes with Groove Design can significantly improve the efficiency and reliability of mechanical systems.
Jf800 Gunmetal & Bronze Bush Groove Bushing can be produced from an ID of 3mm all the way up to 400mm.

Sintered SAE797 Layer + Steel Backing + Copper Plating / Tin-Plating
JF800 bimetal bearings are steel and copper alloy products with low carbon steel plate as the matrix material and sintered CuPb10Sn10 or CuSn6Zn6Pb3 on the surface. The bimetlal t is a double alloy bearing bearing capacity of the strongest one, heavy vehicle balance bridge bushing, gasket; 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.
Bimetal Bearing Design
We can design bimetal bearings according to the operating conditions of copper alloy surface processing of various types of oil tank, oil hole, hole, etc., in order to suit to cannot continue to go hard or go occasion. Good bonding strength and optimum bearing capacity can be obtained by secondary sintering and secondary extrusion.
