ARB Tapered Roller Bearings Guide
Product Description
The ARB 120TQO745 four-row tapered roller bearing consists of two double cone assemblies, a double cup in the center, two single cups, cup spacers, and a cone spacer. Its thin cross-section and increased width provide high load capacity while allowing larger roll neck diameters for improved roll strength. The four-row tapered roller design supports heavy radial loads and axial loads in both directions, while optional cone face notches and helical lubrication grooves help improve lubrication and reduce galling and heat damage. It is specially designed for work rolls, intermediate rolls, and backup rolls in steel, aluminum, and other rolling mill applications.
