NTN 7321DB bearing have two rows of rollers with a common sphered raceway in the outer ring and two inner ring raceways inclined at an angle to the bearing axis. This gives them an attractive combination of design features making them irreplaceable in many demanding applications. NTN 7321DB bearing are self-aligning and consequently insensitive to misalignment of the shaft relative to the housing and to shaft deflection or bending.NTN 7321DB bearing are leading in design and can, in addition to high radial loads, accommodate high axial loads acting in both directions.
The standard range of NTN 7321DB bearing comprises: Open bearings: NTN 7321DB bearing are produced in several designs, depending on bearing series and size. By design, NTN 7321DB bearing can accommodate very heavy radial and heavy axial loads in applications prone to misalignment or shaft deflections. The differences are: the arrangement of the floating guide ring the design of the inner ring and the cages Sealed bearings: Sealed NTN 7321DB bearing have the same features and internal design as basic design spherical roller bearings, but are equipped with contact seals fitted in recesses in the outer ring.
