Bronx partner with SKF for energy efficient backup rolls

Featuring SKF bearing technology, the replacement rollers have been developed specifically for use in levelling systems for ferrous and non-ferrous strip or sheet materials, and are normally available from stock. Bronx levelling machines are used to level hot and cold rolled steel, coated steel, stainless steel and aluminium, with the strip or sheet materials being passed through a series of precision work rolls to remove shape imperfections produced during the initial steel manufacturing process. The backup rollers play a crucial role in this process by supporting and guiding the work rolls. Over time, these rollers can gradually wear and require replacement, to avoid defects being induced in the finished steel products. The Bronx backup rollers each feature a single piece outer ring, to minimise run-out, with a profiled contact area to eliminate stress peaks and tram lines on the work rolls and thus on the finished steel materials. Just as importantly, for users of Bronx Precision Levellers, by incorporating the latest SKF bearing technology, the Backup rollers provide a long operating life, improving productivity and reducing operating costs. The backup rollers feature specially developed hydrodynamic seals that help to reduce lip seal temperature by up to 35 per cent and frictional torque by over 20 per cent. This enables them to last up to three times longer that conventional lip seals and protects each backup bearing from the ingress of contaminants.
