WZB-3 High hardness impregnated brass solid lubrication bearing is improved upon WZB-3  by further enhance the hardness of high hardness brass, giving rise to higher load bearing capacity and better wear-resistant property. The products are widely used in continuous casting rolling machine, mining equipment, engineering equipment, injection-molding machines, etc. Because of its high hardness, it's difficult to machining and finish, it's recommended only for really high load applications.
