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.

Using its AIP Added Value Programme, NSK undertook a full review of the existing design, which included an inspection of the failed bearings.
