NSK has developed a range of long-life, large-size taper & cylindrical roller bearings for gearboxes in large industrial machinery such as wind power generators & mining machinery. Its special material & customised heat treatment technology decrease early damage caused by white structure flaking. Under such conditions, the bearings' life can be enhanced seven times in comparison to conventional bearings.
