FCD106156570 Multi-Row Cylindrical Roller Bearing for Rolling Mills
Role in Rolling Mills
While rolling mills utilize various bearing types, multi-row cylindrical roller bearings are specifically engineered for applications requiring exceptional radial load capacity and rigid support in mill stands.
Typical Installations:
- Backup rolls in 4-high/6-high mills
- Plate mill support rolls
- Continuous casting machine rolls
- Non-drive end applications
Technical Advantages
Optimized Load Distribution
Four-row design shares loads across multiple roller paths for enhanced durability.
Precision Guidance
Maintains roll positioning within ±0.01mm tolerance for superior accuracy.
Thermal Stability
Special heat treatment resists deformation up to 150°C operating temperature.
Configuration Flexibility
Available in FC (solid) and FCD (split) designs for various applications.
Product Series Comparison
FCD Series (Split Inner Ring)
- FCD3045120 Easy maintenance
- FCD5678275 Cluster mills
Complementary Bearing Solutions
For complete rolling mill solutions, these bearings often work with:
Tapered Roller Bearings

Backing Bearings vs. Multi-Row Cylindrical Bearings
While multi-row cylindrical bearings are designed for backup rolls handling heavy radial loads, backing bearings are specialized for work roll support in cluster mill configurations, particularly in Sendzimir mills for precision strip rolling.
