Metal Materials

JDB650 material is made of strong cast bronze based metal with special solid lubricants embedded. It basic material is CuZn24Al6. The base metal withstands high load and the solid lubricants provide for self-lubrication. The bearing shows excellent performance without pre-lubrication under conditions of extreme high/lower temperature with low speed. This material provides a maintenance-free bearing solution, particularly for high load, intermittent of oscillating motion.

For special heavy load application, CLI also can supply the strong cast bronze of special high hardness. The material can be up to HB>270, HB>300.
