Longer-life four-row tapered roller bearings for rolling mills
NSK has developed its four-row tapered roller bearings for rolling mills to offer a number of class-leading performance and environmental benefits. The work roll bearings use newly developed water-resistant grease that is fully sealed into the confines of the bearing. With the new bearings, service life is typically doubled in challenging conditions such as those where there is a high risk of water penetration. In addition, the sealed design means that grease consumption is far less than that exhibited by a conventional "˜open' bearing, while the risk of contaminating the environment is greatly reduced.
