Four Row Cylindrical Roller Bearings

      Four-row cylindrical roller bearings are heavy-duty separable radial bearings, featuring four parallel roller rows for excellent load distribution and rigidity. They are designed to withstand extremely high radial loads at moderate to high speeds.

1. Key features: Separable and interchangeable components (inner/outer rings, roller-cage assemblies); available with cylindrical or tapered bores, and machined brass/steel/pin-type cages; logarithmic profiled rollers reduce edge stress.
2. Advantages: Ultra-high load capacity, high rigidity and precision (P6/P5/P4 standards), durability with high-quality case-carburized steel, low friction and strong versatility.
3. Typical applications: Rolling mills, heavy machinery, gearboxes, crushers, continuous casting machines and mining equipment.
