RNU 204 ECP Cylindrical roller bearings single row without an inner ring

*Cylindrical roller bearings single row without an inner ring*

Cylindrical roller bearings single row without an inner ring provide a solution for applications were hardened and groundraceways are provided on the shaft or in the housing bore. Because RNU designbearings, for example, do not need an inner ring, the bearing arrangement designcan be downsized or the shaft diameter can be larger to provide a stronger,stiffer arrangement. Additionally, the possible axial displacement of the shaftrelative to the housing is only limited by the width of the raceway on the shaftfor the RNU design or in the housing bore for the RN design.

A selection of RNU design cylindrical roller bearings is listed in product table"Cylindrical roller bearings, single row, without inner ring". In case of RNUdesign bearings the inside diameter F_w of the roller complement, whenthe rollers are in contact with the outer ring raceway, lies within the limitsof tolerance F6. Generally, SKF recommends machining the raceways on the shaftto g6 tolerance and the seats in the housing to K6 tolerance. For additional information on machining and materials of raceways seesection"" or contact the application engineering service.
