The world’s largest can manufacturer (soft drinks, isotonic drinks, beers, etc.) was experiencing regular, unexpected, production stoppages due to premature bearing failures in their spray head coating machines. This was causing production disruption 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 purged from the bearing by high pressure air that was used in the process. NSK proposed its non-contact VV seals together with a change to bearing geometry resulting in adequate grease retention and a dramatic increase in bearing life.
