    1. Detailed information

    JBD-1H Ultra-high hardness impregnated brass solid lubrication bearing is further improved upon JDB-1 by adjusting high hardness brass casting process to further raise its hardness, maximizing both its load bearing capacity and wear-resistant property. Due to its reduced ductility, high impact applications should be avoided. Also because of the high hardness of the bearing bush, during design of the bearing set high hardness shaft should be selected to prevent premature shaft wear. JDB-1H are widely used in mining equipment, engineering equipment, and injection-molding machines, etc.
