Description

Koyo single-row cylindrical roller bearings are available in several types.

The NU and N types can adjust to the axial movement of the shaft based on the housing position. These are ideal for use as free side bearings.

With the NJ and NF types, axial load is carried in a single direction.

NUP and NH types are capable of carrying some axial load in both directions.

Type R cylindrical roller bearings have dimensions equal to the standard series, but provide superior load rating. This is possible because the interior of type R bearings has been designed differently. Supplementary code "R" is used for their identification.
