JDB-5 is reinforced product of JDB series. It is based steel GCr15 and embedded with solid lubricant. It is of high compress strength and particularly suitable of supporting position in hositing machines,e.g. Thesupport 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 highload. Due to its superb high hardness, when under high load, it overperforms than other JDB type.

Products of JDB-5 serise are a kind of fortified products. Due to it's excellent comprehensive capability, it's especially suited in the surpporting parts of hoisting machines, for example: surpport of rooter, surpport of hoist engine, surpport of crane and so on. But as for their matrix being steel, they are not suitable for circum-astances with water, acid and alkali.
