Rulmenți cu role cilindrice cu un singur rând fără inel interior

Single row cylindrical roller bearings in the RNU series are cylindrical roller bearings based on the NU design, supplied without an inner ring. These bearings are typically used in applications where hardened and ground raceways are provided on the shaft. Since RNU bearings have no inner ring, the shaft diameter can be larger to provide a stronger and stronger bearing arrangement. Furthermore, the possible axial displacement of the shaft relative to the housing is limited only by the raceways on the shaft.


  • Bearings without an inner ring based on the NU design.
  • Made the shaft diameter larger to provide a stronger, stiffer shaft.
  • Axial displacement of the shaft relative to the housing can be accommodated, limited by the width of the raceway on the shaft.
  • Typically used in applications where the ground raceway can be machine hardened in the shaft.
