Detailed description
cylindrical roller bearings NJ2307E
Four-row Cylindrical roller bearings have an extremely high radial load capacity, but no thrust capacity. This bearing type is mostly used in roll neck and work roll applications in the metal rolling industry.
Full complement Cylindrical roller bearings meet the need for increased radial load carrying capacity by maximizing the number of rollers in a given envelope.
