AUB's four row cylindrical roller bearings are designed for the tough applications in daily use where moderate and high speeds, high radial loads, high temperatures and debris are constantly challenging applications. These bearings have a balanced cross-section design that provides high radial load capacity within the bearing envelope. AUB four row cylindrical bearings are specifically designed to withstand extremely heavy shock loads while running smoothly and accurately in the backup rolls of rolling mill stands. Under particularly harsh operating conditions, AUB's long-life special steel provides significantly higher durability to counteract heavy rolling loads and the possibility of impaired bearing lubrication due to contamination. Available in a large number of design types with high performance cage options and manufactured to close tolerances, AUB four row cylindrical bearings are optimized to provide high capacity and precision for uninterrupted and precise plate making.
