Bearings play an important role in both passenger and goods transport. They have to withstand heavy loads: they work at high speeds, under a great weight, are subjected to both static and dynamic loads and play an essential part in the safety of rail vehicles.

NSK is the leading bearing manufacturer for the Japanese Shinkansen high-speed trains and manufactures wheelset bearings for trains in the British Intercity Express programme, amongst others. Since both the wheelset bearings and the traction motor bearings have a direct effect on a train’s safety, NSK works with the latest technologies, innovative seal solutions and high-strength special steels. The ceramically insulated NSK bearings for traction motors have also proven themselves through a high insulation resistance and reliable use at high speeds and strong shock loads.

Apart from safety aspects, the rail companies also pursue efficiency goals with respect to higher speeds and prolonged maintenance intervals. These requirements are also met by NSK’s wheelset and traction motor bearings through permanent further development and optimisation.
