Application features:
Jdb-250g bearing steel sleeve is a reinforced product with high compression resistance. When the lubricating particles are discharged when inlaid with graphite, a layer of diaphragm is formed between the shaft and the sleeve, which has the advantage of anti seizure compared with single oil lubrication. It is especially suitable for the supporting part of lifting machinery. For example: the support of the soil rolling machine, crane, etc., but it is not suitable for use in water or acid and alkali occasions.
