Four row bearings

Four-row bearings are used almost exclusively for the roll necks of rolling mill stands, calenders and roller presses. Because they are normally mounted with an interference fit on the roll neck, four-row cylindrical roller bearings are well suited for rolling mill applications where the rolling speed is high.

Because four-row bearings can accommodate only radial loads, they are mounted together with deep groove or angular contact ball bearings, or with tapered roller bearings (either radial or thrust design) which accommodate the axial loads.

There are a variety of special features that can be incorporated in the design of four row bearings, such as: face notches, helical bore grooves, extended .Four-row bearings are used successfully worldwide for rolling mill bearing arrangements, particularly as work and back-up roll bearings for hot as well as cold rolling mills. As they can support both heavy radial loads and simultaneously acting axial loads they permit simple and cost effective roll neck bearing arrangements.
