Success Story
Industry: Power Transmission
Application: Bus Gearbox
Cost Savings: $40,374
Introduction
An international manufacturer of angle gears was experiencing frequent failures on gearboxes fitted to a bus application. NSK investigated the application and found the bearing arrangement was complex and involved many components from various suppliers. As a result, NSK proposed a customized solution with an integrated flanged bearing arrangement to simplify the assembly and offer superior performance. A test of the bearing suggestion proved to be successful. The solution was adopted by the customer, resulting in reduced components purchased, consistent and acceptional performance with easier assembly.
