The NSK company
NSK commenced operations as the first Japanese
manufacturer of rolling bearings back in 1916. Ever
since, we have been continuously expanding and
improving not only our product portfolio but also our
range of services for various industrial sectors. In this
context, we develop technologies in the fields of
rolling bearings, linear systems, components for the
automotive industry and mechatronic systems. Our
research and production facilities in Europe, Americas
and Asia are linked together in a global technology
2
network. Here we concentrate not only on the
development of new technologies, but also on the
continuous optimisation of quality – at every process
stage.
Among other things, our research activities include
product design, simulation applications using a variety
of analytical systems and the development of different
steels and lubricants for rolling bearings.
Partnership based on trust –
and trust based on quality
Total Quality by NSK: The synergies of our global network of NSK Technology Centres.
Just one example of how we meet our requirements for high quality.
NSK is one of the leading companies with a long tradition
in patent applications for machine parts. In our worldwide
research centres, we not only concentrate on the
development of new technologies, but also on the continual
improvement of quality based on the integrated technology
platform of tribology, material technology, analysis and
mechatronics.

* Bearing numbers denoted by an asterisk represent availability of either a contact rubber seal or a non-contact rubber seal. The value of limiting speed is for when H preload is applied.
This value is uninfluenced by the type of arrangement. Starting torque shows the numerical value for grease lubrication. Under conditions of oil lubrication, starting torque becomes
1.4 times that of the figures listed above. Permissible axial load becomes 0.7 times that of limiting axial load.
