(July 26, 2011) NKE has supplied a ‘special’ cylindrical roller bearing, with an outer diameter of 3.3m, to help German pipe manufacturer ESW Röhrenwerke achieve a smooth rolling process in its three-roller planetary rolling mill. ESW Röhrenwerke manufactures seamless steel pipes that are used worldwide as structural tubes in machinery, steel constructions, in the automotive industry, as boiler tubes and as pipelines and supply lines for combustible liquids, gases and oil worldwide. Seventy-thousand tonnes of steel pipes are produced each year in the three-roller planetary rolling mill process, with outer diameters of 70mm to 244.5mm and with a wall thickness of between 7.1mm and 60mm. An essential component for this high-reduction process is a large bearing that acts as the front support for the rolling head assembly — this was recently replaced by a cylindrical roller bearing from NKE, with a solid steel cage, outer diameter of 3.3m and weight of 2.2 tonnes. Key benefits of product application: The bearing is loaded with a supporting force of 76.3 tonnes and operates at 125rpm, supporting a rotating mass of around 200 tonnes. Its oil lubrication is low, at 10 litres per minute, while its service life is between six and eight years. NKE was able to provide a large-size bearing quickly. ESW Röhrenwerke claimed that NKE was a reliable and competent partner.
