Four Row Tapered Roller BearingsFour-row tapered roller bearings are one kind of roll neck bearings. Their radial and axial loading capacity are high. They can carry axial loads in two directions, and their radial loading capacity is three times heavier than single-row tapered roller bearings, but the limiting speed is lower. They can be used as axial locating bearings in two directions because they can limit axial displacement in two directions within axial clearance. The radial and axial clearance also can be adjusted by changing the width of the spacer between the inner and outer rings. They are used almost exclusively in work roll applications such as rolling mills. You can get four-row tapered roller bearings in the TQO and TQI designs.
