Design of bearing seats as raceways

In applications with limited space it may be advantageous using a cage and roller assembly with an outer or inner ring only in order to save on sectional height.

In these cases, the rollers run directly on the surfaces of shaft or housing. These contacting surfaces must be hardened and ground as for bearing raceways.

Typical types for these applications are RNU Series or RN series. 

The contacting surface on shaft or housing acting as raceway must be produced to ISO tolerance field g6 and K6 respectively.

The diameters of the guiding flanges on shaft or housing must be in accordance with the respective shoulder diameters (d1) or (D1), as given by the product tables. (NOTE: refer to the data of complete bearings due to these types, RN and RNU are not detailed in the date table and if further information is required, consult us).

For detailed information on the design layout of raceways see chapter Design of bearing location.
