NKE AUSTRIA GmbH supplies rolling bearings for railway vehicles. The available products and services include rolling bearings for traction motors and gearboxes as well as technical services for the railway industry.
A long service life is a key criterion for rolling bearings used in traction motors. The most commonly used bearing types for this application are cylindrical roller bearings, deep groove ball bearings and electrically insulated rolling bearings, which are available as hybrid bearings or with a coated outer or inner ring.
Gearbox bearings run at high speeds and are exposed to significant loads. In addition they must endure shocks, vibrations and extreme temperatures. The bearing types used most commonly here are cylindrical roller bearings, tapered roller bearings, angular contact ball bearings, four-point contact ball bearings and deep groove ball bearings.
In addition to a comprehensive range of rolling bearings for traction motors and gearboxes NKE provides commercial and technical support, including application consulting, development and design, calculation, testing and logistic services. Frequently NKE manufactures tailored rolling bearings for railway applications to customer specifications. In the past years NKE has received orders from numerous well-known companies in the railway industry, including rail operators, service providers and OEM manufacturers.
