Single-row cylindrical roller bearings
The NU and N types exhibit their best performance when used as free side bearings since they adjust to the shaft's axial movement, to a certain extent, relative to the housing position.
The NJ and NF types carry axial load in one direction, while the NUP and NH types can carry a certain degree of axial load in both directions.
Type R cylindrical roller bearings feature enhanced load rating compared with standard series, though both have equal dimensions.This is because type R bearings have different interior design. They are identified by supplementary code "R".
