Bearing Material

NSK has developed TL (Tough and Long Life) bearing material, to overcome the problem of damage due to inner ring fracture encountered on spherical roller bearings in the dryer sections of papermaking machines. In addition to its primary function of preventing inner ring fracture, the material also contributes to an increased surface hardness on the bearing raceways, and provides enhanced dimensional stability under high temperature conditions. It has been developed to address the trend to higher operating temperatures in the dryer sections of paper making machines. Today, with the moves toward higher performance equipment, the temperatures in the hollow cylinder of the dryer section, through which steam or oil passes, can reach 180 °C, sometimes on newer machines, even 200-250 °C.
