Four-Row Cylindrical Roller 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.Inner rings can be provided in a semifinished condition with appropriate grind stock to allow mill operators to optimize the roll’s precision by finish grinding the inner ring after mounting it onto the roll. The part numbers for these bearings and inner ring assemblies are identified by a CF suffix. Inner rings can also be provided in a finished state with no additional grinding required. They may be furnished with a tapered bore for your application. Broad line contact between the rolling elements and races provide high radial load capacity within the bearing envelope. In addition, multiple cage designs and materials allow for design flexibility and preset radial clearance simplifies the installation process
