An international manufacturer of elevator gearboxes was experiencing unscheduled failures on its product during operation. NSK investigated the bearings within the application and found that a complex and difficult to assemble bearing arrangement was causing the inconsistent and inadequate performance. NSK suggested a much simpler solution featuring a fully integrated bearing assembly unit. This two-row flanged bearing unit reduced the number of components, was easier to assemble and offered superior performance compared to the original assembly.
