NTN NN4921 Bearing



Product Description:

NTN NN4921 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 NN4921 bearing are self-aligning and consequently insensitive to misalignment of the shaft relative to the housing and to shaft deflection or bending.NTN NN4921 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 NN4921 bearing comprises: Open bearings: NTN NN4921 bearing are produced in several designs, depending on bearing series and size. By design, NTN NN4921 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 NN4921 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. Bearings for vibratory applications

NTN Roller Bearings ! MISUMI

NTN’s pioneering efforts in developing crowned rollers have resulted in greater load.carrying capability and longer bearing life. Crowned rollers under load distribute stress equally along their full length of contact with the raceways, thereby eliminating stress concentration at the roller ends.
