Roll neck bearng for rolling mills contain three types:

Four-row taper roller bearing,

Four-row cylindrical roller bearing,

Double-row taper roller bearing.


Four-row tapered roller bearing: These bearings mainly used for work rolls for intermediate rolls of their radial and axial loading capacity are high, adjust of internal clearance is not required, facilitating handing, open type is also available.


Four-row cylindrical roller bearings: These bearings used for back-up rolls, have a superior large radial load capacity, and are suitable for high-speed rotation. rolling accuracy can be improved by applying the tight fitting of the inner ring onto the roll jourmal, and then applying the integral system grinding of the inner ring raceway.


Double-row taper roller bearing : These bearings used for back-up rolls, have a large axial load, the inner ring has key way applicable to each key.
