JDB-450钢板浇铸轴承,实在钢套的基体内,离心浇铸铜层后镶嵌固体润滑产品,除具有JDB-650的功能外,还能节省成本,提高抗压强度。他打端面可以与基体焊接安装使用,因此适用于冶金机械,建筑机械和输油机械中等不可以加油的领域br>JDB-has almost the same constucture as JDB-650.Suitable for lowload position,wear performance worsens when under middle or high load.The mating layer is same as JDB-so that more cost-saving than JDB-whereas compression strength increases and weldable.Most suitable for dry position in construction,metallurgical machines,conveyor machines,conveyor machines etc.
