1 BEARINGS FOR INDUSTRIAL MACHINERY NSKHPS HIGH PERFORMANCE STANDARD

2 As one of the world s leading manufacturers of rolling bearings, linear technology components and steering systems, we can be found on almost every continent with production facilities, sales offices and technology centres because our customers appreciate short decision-making channels, prompt deliveries and local service. Europe Asia The Americas Africa Oceania The NSK company NSK commenced operations as the first Japanese manufacturer of rolling bearings back in 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 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. 2

3 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.

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.
