A drinks company in the UK were experiencing premature bearing failures due to an unknown reason, believed to be contamination. Bearing lifetime was 1 week. NSK was contacted to evaluate the source of failure. NSK engineers identified the true cause of failure was due to residual magnetism causing Eddie Current Braking. The source of the magnetism could not be changed. Therefore an alternative bearing or design was needed. NSK solution resulted in bearing lifetime increase : from 1 week to 1 year.
|Before||Cost p.a.||NSK Solution||Cost p.a.|
|Annual bearing cost 3328 x 1.58€||5.283 €||Annual bearing cost 64 x 2,81€||180 €|
|59€ per hour x 2 people x 52 time per year||5.772 €||0 €|
|Total Costs||€ 11 055||€ 180|
