The world’s largest can manufacturer (soft drinks, isotonic drinks, beers, etc.) was experiencing regular, unexpected, production stoppages due to premature failure of the bearings fitted to the spray head inside coating machines. This was causing significant disruption to production and high downtime costs. NSK conducted a full evaluation of the application including grease analysis and found that the bearings were seizing due to grease being ejected from the bearing by high pressure air that was needed for the process. NSK proposed its non-contact VV seals together with a change to bearing geometry resulting in good grease retention and a dramatic increase in bearing life.
