SKF is supplying bearings for use in energy-efficient backup rollers suitable for retrofitting to Bronx precision levelling machines.

Bearings improve energy-efficiency of backup rollersBronx Engineering has partnered with SKF to launch a new 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 specifically for use in levelling systems for ferrous and non-ferrous strip or sheet materials, offering exceptional performance and long-term reliability.

These newly developed replacement Backup rollers 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 on the finished steel materials too.

Just as importantly, for users of Bronx Precision Levellers, by incorporating the latest SKF bearing technology, the backup rollers provide a long and trouble-free operating life.

The Backup rollers also benefit from 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, plus it protects the bearings from the ingress of contaminants under even the toughest operating conditions.
