Basic Features

The JDB-250 Graphite Cast Iron Inserted Lubricating Bearing is a new product made with HT250 as the base material and embedded with solid lubricant, representing a typical material-saving product. It can be used as a substitute for the JDB-650 under conditions of pressure less than 14.5N/mm2 or when mechanical property requirements are not high. However, it is not suitable for use in water or in acidic or alkaline environments.
