Longer life bearings

Responding to these demands, NSK has developed a programme that delivers innovations in materials, production techniques and lubrication technologies.

The programme has achieved a 30% improvement in efficiency for NSK's standard deep groove ball bearings, and an even larger 47% saving for domestic appliance bearings: both compared to conventional ball bearings of the same size.

NSK has collaborated with leading steel makers to improve the steel making process, reducing impurities substantially and achieving a decrease in AI2O3 alumina oxides. The resulting long-life Z Steel is now the standard material for NSK's ball bearings.
