NSK Four-Row Cylindrical Roller Bearings: High Capacity & Long Life

NSK four-row cylindrical bearings are engineered specifically to accommodate the extremely heavy and impact loads – while running smoothly and accurately – in the back-up rolls of rolling mill stands. Amid particularly harsh operating conditions, NSK’s long-life Super-TF steel provides significantly higher durability to counteract the heavy rolling load and the high probability of compromised bearing lubrication due to contamination.
