应用特点:
JDB-250G bearing steel sleeve is a reinforced product with extremely high compressive performance. When graphite is embedded, lubricating particles are discharged, creating a layer of diaphragm between the shaft and sleeve, which has the advantage of anti bite compared to single oil lubrication. Especially suitable for the supporting parts of lifting machinery. For example: support for soil rollers, crane support, etc., but not suitable for use in water or acidic or alkaline environments.
