An international manufacturer of elevator gearboxes was experiencing irregular and unscheduled stoppages of its product during operation. NSK investigated the problem and found out that there was a complex and difficult to assemble bearing arrangement resulting in inconsistent performance. NSK implemented through its machine design consultancy service 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, gave superior performance and had the benefit of supplier rationalisation.
