- 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.

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.

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.

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.
