Four-Row Cylindrical Roller Radial Bearings
Timken’s four-row cylindrical roller bearings are designed for the rigors of daily use in applications where moderate and high speeds, high radial loads, elevated temperatures and debris are constant challenges. Designed with well-balanced cross sections, these bearings provide high-radial-load capacity within the bearing envelope.
The radial internal clearance (RIC) for the bearing assembly must be included when ordering either a) the complete assembly or b) with the inner-ring set. It is advisable to order the inner-ring set independent of the outer ring set when the final grind of the inner-ring O.D. is accomplished after mounting on the roll neck.
Four-row cylindrical roller bearings are used almost exclusively for the roll necks of rolling mill stands, calenders and roller presses. 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.
