JDB-50is a reinforced product of JDB series. It is based on steel GCr15 and embedded with solid lubricant. It is of high compress strength and particularly suitable for supporting position in hoisting machines,e.g. The support or stand of windlass and of crane. But it should not be applied in 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 other JDB type
