RNU series single row cylindrical roller bearings are based on the NU design cylindrical roller bearings and supplied without an inner ring. These bearings are typically used in applications where hardened and ground raceways are provided on the shaft. Because RNU bearings do not have an inner ring, the shaft diameter can be larger to provide a stronger, more rigid bearing arrangement. Additionally, the possible axial displacement of the shaft relative to the housing is limited only by the raceway on the shaft.
- Based on NU design bearings without an inner ring
- Enable the shaft diameter to be larger to provide a tronger, stiffer shaft
- Can accomodate axial displacement, of the shaft relative to the housing, limited by the width of the raceway on the shaft.
- Are typically used in applications where hardened an ground race ways can be machined in the shaft
