Cold rolling is a demanding process – not only as a result of severe mechanical and operating environment stresses, but also due to the demands for increased throughput, stringent material quality and finish, high dimensional consistency, increased energy efficiency, and maximum machine uptime.
To accommodate, NSK work roll bearings deliver maximum performance, durability and service life through advanced material, seal and lubrication technologies. For optimized precision of cold-rolled steel, NSK back-up bearings for rolling stands and cluster mills accommodate heavy rolling loads while running with high rotational accuracy.
For the heavy rolling loads in back-up rolls in rolling mill stands, NSK Super-TF Four-Row Cylindrical Roller Bearings equipped with stud-type cages and solid rollers optimize load carrying capacity and minimize risk of roller damage.
