| Oil Hole is necessary to design if bimetal bushings have lubricated
sufficiently; the following oil hole design is recommended, which
is also suitable for bimetal series without special requirements. |

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.

We can solve bimetal bushings bearings solutions for you.
Bi-metallic bushing is formed from steel strips with alloy lining
material. The alloy lined surface can be machined oil grooves,
holes, formed Indentations etc according to different application.
It is suitable for high load, lower speed oscillation & rotation
movement.
