Plastic and ceramic material bearing at NSK
Bearing materials development at NSK is not only about steel. Plastic materials, as well as non-ferrous metals such as brass, are also tested in order to make precisely targeted improvements to the characteristics of cages. Furthermore, ceramics and ceramic coatings (Image6) play an increasing role when adjustments are needed to the electrical conductivity properties of bearings and their resistance to wear.
On this subject, NSK has recently introduced a ceramic development called HDY2, which features optimised insulation and thermal conductivity characteristics.
Finally, another focus area for materials development concerns lubricants. Tribology is a separate core competency in NSK’s research and development organisation, alongside materials technology.
