A change of bearing type on the carousel of a casting line, coupled with a small recommended design change, has led to savings of €100,095 per annum at a leading manufacturer of gas turbine blades after it began experiencing bearing failures every six weeks.
Due to the short service lifetime demonstrated by its existing bearings, the manufacturer decided to call upon the specialist team of application engineers at NSK. Using its AIP Added Value Programme, NSK undertook a full review of the existing design, which included an inspection of the failed bearings.
