Four-row tapered roller bearings, TQO design
Four row tapered roller bearings are the one kind of roll neck bearings, their radial and axial loading capacity are high, can carry heavy axail loads in two directions, and their radial loading capacity is 3 times heavier than single row tapered roller bearings, but limiting speed is lower.Four row tapered roller bearings are the one kind of roll neck bearings, their radial and axial loading capacity are high, can carry heavy axail loads in two directions, and their radial loading capacity is 3 times heavier than single row tapered roller bearings.
The four-row tapered roller bearings has the same load capacity as the double-row tapered roller bearing, but its radial load bearing capacity is greater, the limit speed is slightly lower, the basic size is larger, and it is often used in heavy machinery.
