When the world’s largest beverage can producer was experiencing common, sudden manufacturing stoppages because of the untimely failure of spray-head bearings in its coating machines, the corporate turned to the experience of NSK. Recommending NSK deep groove ball bearings that includes VV sequence non-contact seals helped the plant to get rid of failures and obtain spectacular annual financial savings of €240,000.

The meals and beverage business is extraordinarily demanding, not least as a result of manufacturing line stoppages can show costly in all types of functions. Manufacturing aluminium cans for tender, isotonic, and alcoholic drinks is not any exception, notably when the corporate occurs to be the world’s largest beverage can producer.
Repeat failures of the spray-head spindle bearings within the manufacturing facility’s can-coating machines was inflicting vital disruption to manufacturing and dear downtime on a high-volume manufacturing line. The corporate tasked NSK with resolving the difficulty.
Professional NSK engineers carried out a full analysis of the applying, together with complete bearing and grease evaluation. From this exercise it was attainable to infer that the bearings had been seizing because of the ejection of bearing grease by high-pressure air wanted for the method. Insufficient bearing seals had been failing to stop this undesirable impact.
As a part of an entire worth proposal, NSK really useful the adoption of its deep groove ball bearings with VV sequence non-contact seals and C3 inside clearance geometry. Providing excessive efficiency in contaminated environments, this progressive configuration seals successfully with out growing both torque or working temperature. Notably, the non-contact lip design reduces bearing drag, an necessary benefit the place energy loss is crucial.
The NSK resolution resulted in wonderful grease retention whereas nonetheless permitting high-pressure air stream by means of the bearing as a part of the machine’s working process. Most significantly of all, the can manufacturing plant witnessed a dramatic enhance in bearing life: from 7 to 110 days of operation, after which routine upkeep occurred. The shopper is benefitting from prolonged bearing life, alongside elevated productiveness and decreased upkeep prices, leading to annual financial savings of €240,000.
