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
- Precision Guidance – Maintains roll positioning within ±0.01mm tolerance
- Thermal Stability – Special heat treatment resists deformation up to 150°C
- Configuration Flexibility – Available in FC (solid) and FCD (split) designs
Product Series Comparison
FC Series (Solid Design)
- FC2842125 – For medium-section mills
- FC3652168 – Heavy plate mill variant
- FC5276280 – Extra-large bore design
FCD Series (Split Inner Ring)
- FCD3045120 – Facilitates maintenance
- FCD5678275 – For cluster mill applications
Complementary Bearing Solutions
For complete rolling mill solutions, these bearings often work with:
1. Tapered Roller Bearings
- Work roll applications
- Drive-end installations
2. Thrust Bearings
- Axial load management
- Mill screw-down systems
Selection Guidelines
- Load Analysis: Calculate dynamic equivalent load (P = Fr for pure radial)
- Speed Considerations: DN value ≤ 300,000 mm/min
- Lubrication: Prefer oil-air systems for high-speed applications
