Jdb has both the virtues of the copper alloy and the solid lubricant. Can be applied under dry, high temperature, high pressure, corrosive, water or other chemical envioroments, where no oil can be introduced.
It is widely applied in casting machines, steel rollers in metallography, mineral machines, ships, turbogenerators and hydraulictubine and injection molding machines.
