Appliation
- ZY-JDB-1 Can be used low,middle and high load. When under high load, wear peformance degrades accordingly. It's a general-purpose product and be applied under low or high pressure, low or high temperature, and oil, water or dry lubrication. Can be applied in consistent cast machine, rolling machine, conveyor equipment; plastic injection machine, high voltage switch; hoisting supporter, hydraulic gate supporter; paper-making machine, automobile die etc.
- ZY-JDB-2 is also one type of JDB series.It is base on bronze CuSn6Pb3 and evenly embedded with a solid under low load,high temperature and middle speed,e.g.gemel is furnace gate,convery way of the baking furnace,light industry and tooling machine industry etc.
- ZY-JDB-3 has almost the same constructure as JDB-2.Suitable for lowload position,wear performance worsens when under middle or high load. The mating layer is same as JDB-2 so that more cost-saving than JDB-2 whereas compression strength increases and weldable. Most suitable for dry position in construction, metallurgical machines, conveyor machines etc.
- ZY-JDB-4 is based on cast irom Ht250 and embedded with solid lubricant.Very good performance when under low load. Not suitable for middle and high load. A typical cost saving material, can substitute JDB-2 to be applied in the position without high requirements such as die guider, plastic injection machines etc.
- ZY-JDB-5 is reinforced product of JDB series.It is based steel GCR15 adn embedded with solid lubricant.it is of high compress strength and particularly suitable ofr supporting position in hoisting machines,e.g.The support or stand of windlass and of crane.But it should not be appliedin water or in acid/alkali circumstance. Can be used under low,middle and high load. Due to its superb high hardness, when under high load, it overperforms than other JDB type. Not suitable for water,acid,ahkili circumstances. Most suitable for the supporting position of hoisting machine, e.g. bulldozer supporter, hoister supporter, reeling machine supporter etc.
