Material structure
Basic characteristics
Jdb-250 nodular cast iron inlaid lubrication bearing is a new product with HT250 as base material and solid lubricant, which is a typical material saving product. If the pressure is less than 14.5n/mm2, or the mechanical property requirements are not very high, it can be used as a substitute for jdb-650. But it should not be used in water, acid or alkali.
