JDB-1 Solid Lubricant Embedded Bush

JDB-1 Solid Lubricant Embedded Bush

Application：

The products bases on alloy of bronze of special formula(CuZn24AL6). The solid lubricating medium is inlaid in the friction surface and the friction area of the solid lubricating medium take over 20%.The combination of advantages of alloy of bronze and non-metal Friction reducing matercing has broken in the limit of general bearing that depend on oil film. It was widely used in metallurgy, stell rollers in metallography, mineral machine, ships gas turbine and ect.
