Discover our standard and special application ranges. Benefit from the reliability and performance of the cylindrical roller bearings from NTN & SNR.

Cylindrical roller bearings

Cylindrical roller bearings (CRBs) are used in countless industrial applications, such as reduction gears for robots or rail machineries, gear motors for fixed machineries, gearboxes for mobile equipments and speed multipliers for wind turbines. Designed to support high radial loads, they can also withstand axial loads if they feature shoulders on their inner and outer rings.

Two categories are available: 

  • with a cage: high accelerations, high rotation speeds and high radial loads
  • without a cage: the maximum quantity of rollers is used, and the supported loads are higher than CRBs with cages, however the rotation speed will be moderate

Focus on our range of cylindrical roller bearings:

  • Bearing types:
    • 1 row: NU, NJ, NUP, N, NF, NH, NJV, NFV
    • 2 rows: NNU, NN, SL
    • 4 rows: 4R
  • Dimensions: bore diameter from 20mm to 1250 mm for the standard range and beyond for tailor-made range

To ensure optimal contact pressure distribution and thus contribute to improved service life, NTN-SNR continues to work on the roller-to-ring contact performance.
Our cylindrical rollers have today an optimized shape in order to limit the overpressures at the ends of the rollers (edge effect). As a result, the overall service life of the bearing is directly increased, even in applications with some misalignment.
