JDB-3 Solid lubricating bearings
JDB-3 steel and bronze inlaid bearing, after the steel sleeve base body integrally sintered bronze powder embedded solid lubricant solid lubrication products, in addition to a function of JDB-2, but also to save costs and increase the compressive strength. It can be used with the base end surface welding installation, and therefore not suitable for refueling metallurgical machinery, construction machinery and oil machinery.
