JDB-4 product description
JDB-4 cast iron lubricated embedded bearing is a new product with HT250 as the base material embedded with solid lubricant, which is a typical material-saving product. If the pressure is less than 14.5N/mm2 or mechanical properties are required, it can be used as a substitute for JDB-2 material. It can greatly reduce the cost and meet the requirements of use. For example: mold guide posts, injection molding machine mold bases and other fields can be used.
