NTN Bearing NN4921 design bearings have two stamped window-type steel cages, an inner ring without flanges and a guide ring centred on the inner ring. The CC design is indicated by the designation suffix C or CC. Large CC design bearings with the designation suffix EC or ECC have an optimized internal design for increased load carrying capacity.
NTN Bearing NN4921 design bearings have two stamped window-type steel cages, an inner ring without flanges and a guide ring centred on the inner ring (d ≤ 65 mm) or on the cages (d >65 mm). They have an annular groove and three lubrication holes in the outer ring. NTN Bearing NN4921 design bearings are indicated by the designation suffix E. All E design bearings have an optimized internal design for increased load carrying capacity.
