SKF’s railway axlebox with cylindrical roller bearings was the first to pass the 25-tonne test under the new standard EN 12082 (European Norm). The standard has been introduced to define bearing requirements for railway applications.
For years, the trend in the railroad industry has been to carry higher loads at faster speeds. Today, most
railway cars in Europe are built to run with axle loads of 22.5 tonnes. A significant proportion of newly ordered freight cars will be built for 25-tonne axle loads. Increasing the axle loads to 25 tonnes requires new specifications and bearings.
