Because they are normally mounted with an interference fit on the roll neck, four-row cylindrical roller bearings are well suited for rolling mill applications where the rolling speed is high. Because four-row cylindrical roller bearings can accommodate only radial loads, they are mounted together with deep groove or angular contact ball bearings, or with tapered roller bearings (either radial or thrust design) which accommodate the axial loads.
Series of four-row cylindrical roller bearings
Our basic design four-row cylindrical roller bearings are available in several designs. The major design differences between the bearings are the number of inner and outer rings, the ring designs (flange configurations), and the cage design and material.
Features of four-row cylindrical roller bearings
- Higher radial load capacity
- Lower friction
- Compact internal structure
- Higher stiffness
- Higher precision
- High rotating speed
Appilications of four-row tapered roller bearings
Four-row cylindrical roller bearings are used almost exclusively for the roll necks of rolling mill stands, calenders and roller presses.
