FAG Four Row Tapered Roller Bearings for Rolling Mills

FAG tapered roller bearings can support high radial and axial loads. They have a broad range of speeds. They are efficient at supporting forces and ensure a precise and rigid shaft guidance system due to the large effective distance between the bearings. Tapered roller bearings can be adjusted and dismantled, which makes mounting easy.Due to the inclined position of the rollers, tapered roller bearings can support both radial and axial forces. Four-row and double row tapered roller bearings are used in rolling mills.Due to the inclined position of the rollers, tapered roller bearings can support both radial and axial forces. Four-row and double row tapered roller bearings are used in rolling mills.Tapered roller bearings are separable; unlike cylindrical roller bearings, however, it is not possible to fit the inner rings on the neck first, mount the outer rings in the chock and then slide the chock onto the roll neck. The complete bearing must instead be mounted in the chock, after which the chock together with the bearing is slid onto the neck. This means that the bearing inner ring must have a loose fit on the neck, although it should technically have a tight fit due to the circumferential load. With a loose fit, the inner ring will inevitably creep on the neck. The neck will undergo heating and wear in this case. Wear can be restricted by good lubrication of the fit joint between the inner ring and roll neck.
