Overview
Technical Parameter
JDB-4 cast iron embedded bearing is a new product based on HT250 and embedded with solid lubricant. It is a typical material saving product. If the pressure is less than 145N/mm ² or the mechanical performance requirements are met, it can be used as a substitute for JDB-2 material. It can greatly reduce costs and meet usage requirements.
