[Application Features] JDB-4 cast iron inlaid bearing, is HT250 for the substrate embedded with solid lubricant of new products, is a typical provincial wood products. If the pressure <14.5N / mm2 or occasion mechanical performance requirements, can be used for JDB-2 material substitutes. Can greatly reduce costs, meet the requirements. [Application] For example: field guide post of mold, injection molding machine mold, etc. can be used. The main parameters bearing matrix material: HT250 Dynamic load limit: 60N / mm2 basic hardness: HB180 ~ 230 friction coefficient μ: <0.18 maximum operating temperature: 400 ℃ Highest sliding velocity: 0.5m / s
