Jdb-4 cast iron inlaid bearing, which is a typical province material product, is a new product embedded in solid lubricant with HT250. If under pressure < 14.5N/mm squared or mechanical performance requirements can be used as substitutes for JDB-2 materials. Can greatly reduce cost, meet the use requirement. For example: mold guide column, injection molding frame and other fields can be used completely.
