Double Row Cylindrical Roller Bearings

In terms of performance, the advantages of double-row cylindrical roller bearings are concentrated in "load bearing", "rigidity" and "adaptability". First, **Strong radial load carrying capacity**: The double-row design makes the radial dynamic load rating 60%-90% higher than that of single-row cylindrical roller bearings of the same size, and 2-3 times higher than that of deep groove ball bearings. It can withstand the heavy load of rolling mills, crushers and other equipment. second, the **high rigidity advantage is significant**: the symmetrical layout of the double-row rollers greatly improves the radial stiffness of the bearing. The radial stiffness of the P4-level precision model is more than 50% higher than the single-row model, and can stably support the high-speed cutting of the machine tool spindle. The radial force during cutting ensures machining accuracy; third, **Flexible axial compensation**: the separable structure allows the inner ring or outer ring to move slightly al…
