| Characteristic | The bearings accommodate high axial load carrying capacity thanks to new design of ribs and roller face; the good contact condition ensures good lubrication and low running temperature in roller flange contact area. These characteristics make BND 4-rows cylindrical roller bearings more versatile, using properties and working life, can repalce SKF FAG in rolling mill field. | |
| Application | Rolling mills required high speed and precision, for example: wire mills, bar and shape mills, cold or hot sheet mills and cogging mills. | |
