Bronx Engineering has partnered with SKF to launch a range of energy-efficient replacement Backup rollers for use with all existing Bronx precision levelling machines.
Featuring SKF bearing technology, the replacement rollers have been developed for use in levelling systems for ferrous and non-ferrous strip or sheet materials, offering high performance and long-term reliability.
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 are said to play a crucial role in this process by supporting and guiding the work rolls.
Each unit features 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.
For users of Bronx levelling machines, productivity is maximised and operating costs are reduced.
The Backup rollers also use 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, enabling them to last up to three times longer that conventional lip seals and protecting each Backup bearing from the ingress of contaminants under even the toughest operating conditions.
The latest range of energy efficient Bronx Backup rollers are suitable for all Bronx levelling machines, regardless of age.
