  • High-performance Product Series For Steel Production/Rolling Equipment


    This pamphlet introduces the high performance products (bearings, driveshafts, oil seals) contributing to stable operation of steel production equipment.
    The pamphlet is broken into two sections; one covering examples of application in the field and the other introducing individual products.

  • Cylindrical Roller Bearings for Multi-roll Mill Backup Rolls


    This bearing is used in multistage cold rolling mills. The outer ring is subjected to load due to directly making contact with the intermediate roll, therefore it has been given both surface hardness and strong impact ability through the adoption of special bearing material and heat treatment. This has increased its reliability even further. Furthermore, with JHS210 we have responded to customers' demand for a longer service life. This pamphlet features the handling of bearings (disassembly and inspection procedures) and case studies of bearings, damage and countermeasures.
