RHP was formed in England in 1969 following the merger of three bearing manufacturers.With the merger of these three bearing companies and the rationalisation of their product ranges many bearings became obsolete.NSK is one of the world’s leading manufacturers of bearings, linear technology and steering systems. We ensure motion with the utmost precision – even under the most difficult operating conditions.NSK bearings run in wind turbines and machine tools, our linear technology can be found on production lines for a variety of industries, and our automotive components are installed in vehicles.
