JDB-NO.1
Can be used under low, middle and high load. When under high load, wear performance degrades accordingly.It's a general-purpose product and can be applied under low or high pressure, low or high temperature, and oil, water or dry lubrication.The base material is high strength brass and its hardness doubles than normal bronze so that wear performance improves in large degree.
JDB-NO.2
Suitable for low load position, wear performance worsens greatly when under middle or high load.
JDB-NO.3
Suitable for low load position, wear performance worsens when under middle or high load. The mating layer is same as JDB-Ⅱso that more cost-saving than JDB-Ⅱwhereas compression strength increases and weldable.
JDB-NO.4
Very good performance when under low load. Not suitable for middle and high load.
JDB-NO.5
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.
