TL RUB Self-Aligning Cylindrical Roller Bearings

Engineered to withstand the thermal stresses that prevail in paper machine dryer cylinder applications, NSK’s TL-RUB series bearings are specifically designed to accommodate roll extension, misalignment and shaft deflection on the guide end position of dryer rolls.

TL RUB Self-Aligning Cylindrical Roller Bearings

Design Features

  • Special design NU-type single row cylindrical roller bearing with an aligning ring
  • High-capacity internal design parameters, with optimized size and quantity of rollers
  • Inner rings manufactured with long-life TL material composition and carbonitriding heat treatment process
  • Corrosion-resistant phosphate coating on the aligning ring
  • With heavy-duty machined brass roller guided cage suitable for high loads, high speeds and high temperatures
  • Stabilized for temperatures as high as 200°C
  • With tapered bore
  • For dimension series 22, 23 and 31; additional types available - contact NSK
  • With conventional and custom clearances

Operating Benefits

  • Dimensionally interchangeable with spherical and toroidal bearings for easy upgrade
  • Superior resistance to inner ring crack damage resulting from thermal stress
  • Smoothly absorbs axial thermal expansion of the roll, eliminating wear to the housing bore surface
  • Self-aligning capability accommodates misalignment and shaft deflection, minimizing the effects of edge loading

Fields of Application including

  • Paper making machinery
