产品简述
JDB、JFB（翻边轴套）镶嵌式固体润滑轴套是以特殊配方的高力合金黄铜为基体。并在合金摩擦面上开出排列有序大小适当的孔穴，固体润滑剂磨擦面积达25%。这种合理性的结合综合了铜合金和非金属减磨材料的各自互补优点，完全突破了一般轴承依靠油膜油脂润滑的界限性，实现了无油润滑，并能稳定可靠的应用在各种机械中。
INTRODUCTION
JDB JFB（FLANGED）SOLID LUBRICANT EMBEDDED BUSH IS BASE ON SPECIAL STRONG BRASS ALLOY MATERIAL,ON THE SURFACE OF WHICH DRILL REGULAR HOLES AND EMBEDDED WITH SHAPED SOLID LUBRICANT WHICH FRICTION AREA UP TO 25%OF TOTAL.IT COMPOSES BOTH THE ADVANTAGES OF METALS AND NON-METALLIC AND BREA THE BOUNDS OF OIL LUBRICANTING,BRING ABOUT OILLESS SELF-LUBRI-BANTING,NOW IT IS WIDELY USED IN KIND OF MACHINES.
优点与用途
JDB具有低的摩擦系数，高承载的能力及使用寿命长优点。特别适用于无法加油润滑场合，例如高温、高负载、低速度、防污、防蚀以及在水中式其它溶液浸润而根本无法加润滑油脂的特殊工况条件下使用。目前已广泛应用于冶金、矿山钢铁、船舶机械、海洋工业机械、起重升降机械、包装机械、注塑机械、食品机械、灌装机械、工程机械、水工机械、水轮机、汽轮机、机床工业和其它工业机械等领域。
ADVANTAGES AND APPLICATION SCOPE
JDB JFB HAVE LOWER FRICTION,HIGHER LOAD AND LONG LIFE.IT IS MOST APPROPRITE FOR HIGH TEMPERATURE.HIGH LOAD AND THESE UNDER WATER AND OTHER SOLUTIONS WHERE OILS ARE DIFEICULT TO BE APPLIED OR OILS AREN'T PERMITTED .IT IS WIDELY USED AS METALLURGY, MINING MACINES,SHIP BUILDING, MARINE MECHANISMS PACKAGE MACHINE,INJECTION MACHINE,FOOD MACHINE ENGINEERING MECHANICAL,AEROSPACE CRAFT,WATER TURBINE,GAS TURBING MACHINE TOOLS AND SO ON.
