Product informationAbout Us

WZB-4  Graphite-impregnated bronze bearings are customer-specified products. In many cases, previously using 5-5-5 bronze which does not possess self-lubricating property, if lubrication becomes insufficient, will result in binding and failure of the bearing. WZB-4 was developed to solve this problem. By impregnating graphite in certain designed pattern into working surface of the bearing, the product can operate in dry conditions through the mechanism of solid lubrication. JDB-7 can be used in high temperature environments, such as hot steam rolling equipment, paper making machineries, etc.
