disadvantages of old rolling mill stands

Early and old types rolling mill stands were different from modern mill stand. Usually spherical roller bearings were installed onto the roll neck, meeting the production requirements at that time. However, it became outdated with more and more  problems as steel mills have higher demand for rolling mill delivering speed.

Disadvantage Shorter bearing working life leading to higher bearing consumption, Lower precision of steel products, More wear on roll neck, More endplay for the rolls

UPGRADING YOUR MILL STANDS

What ESG Bearing can do for you? No  cost for upgrading without changing the rolls and bearing housing Maintaining the production requirements of carrying loads of production requirements

Advantage

★ Minimizing the roll run-out with interference fit of bearing inner ring and roll neck ★ Allowing higher radial loads and higher rolling speed ★ Higher precision of steel products ★ Convenient for mounting and dismounting, with separated and interchangeable inner      rings and outer rings ★ Reducing rolling mill downtime and maintenance

RADIAL ROLLER BEARING carrying higher radial loas and improving rolling mill precision

AXIAL BALL BEARING carrying axial loads to stop axial movements of the rolls
