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
