Four-Row Cylindrical Roller Bearings are specially designed for rolling mill applications, where extremely high radial loads, shock resistance, and long service life are required. These bearings provide high radial load-carrying capacity, excellent stiffness, and can accommodate high speeds with proper lubrication.
Unlike single-row or double-row cylindrical roller bearings, four-row designs distribute loads more effectively, making them the preferred choice in steel mills and metal processing industries.
Extremely high radial load capacity - suitable for rolling mill working conditions.
Compact structure - optimized internal geometry to carry heavy loads in limited space.
Excellent performance under impact and vibration - suitable for demanding rolling operations.
Interchangeable components - outer rings, inner rings, and rollers can be separated for easy mounting and maintenance.
Extended service life - advanced heat treatment and precision grinding improve durability.
Four-row cylindrical roller bearings are generally produced in the FC, FCD, and FCDP series.
Typical Models (d × D × B, mm):
FC3042120: 150 × 210 × 120
FCD4064270: 200 × 320 × 270
FCDP5476390: 270 × 380 × 390
FCD6492230: 320 × 460 × 230
FCDP82116320: 410 × 580 × 320
FCDP100145430: 500 × 720 × 430
Size Range: Bore diameter from 150 mm up to 1000 mm, outside diameter up to 1500 mm.
Four-row cylindrical roller bearings are mainly used in rolling mill equipment, especially where heavy radial loads are present and axial loads are carried separately by thrust bearings.
