Size range: Inter diameter:120-1320mm
Material: GCr15/GCr15SiMn/G20Cr2Ni4A
Features: 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.
Application: the working roll necks of hot or cold rolling mills, and roll neck of cogging mills. They usually clearance fit with roll necks to being mounted and dismounted conveniently.

Four-row tapered roller bearings are specifically designed to withstand extremely high radial loads combined with heavy axial loads in both directions, making them an ideal solution for the most demanding industrial applications. With four rows of precision-engineered tapered rollers arranged in a compact structure, these bearings provide exceptional load distribution, outstanding rigidity, and superior resistance to shock and vibration.
