Extended Life in High Heat, High Speed Applications
  • In papermaking applications, including dryer and calendar roll sections, the forces at work on bearings become extreme. Compounding very high speeds with high heat and the potential for contamination, the impact of a single bearing failure on uptime and profitability can be severe.

    NSK engineered the TL – Tough & Long Life – spherical roller bearing to run for prolonged intervals under these exact conditions, with markedly superior dimensional stability. A softer core bearing steel combines with proprietary heat treatment on ring surfaces. This advanced process provides both the shock resistance to prevent fracturing, and the raceway hardness needed for long bearing life. These application-optimized bearings can achieve more than twice the service life of conventional bearings, reducing maintenance, downtime and operating costs.

      NSK’s TL steel can be incorporated in a standard specification. Inner-ring fracture strength outperforms bainitic steel, and equals that of carburized steel inner rings, without sacrifice to inner-ring hardness, so that bearing life is not compromised.
