JDB-4 is made of HT250 as the basis and embedded with solid lubricant. It is a typical material saving product. The product can be used as a substitute of JDB-2 if the pressure is <145N/mm² or the requirement in mechanical performance is not high, to greatly reduce the cost and meet the use requirements.It can be used in fields such as guide post of mold, mold-frame of plastic injection machine.
