Product Details:

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.

 

HEROe Bearing _ NTN SNR

The hybrid bearing that NTN.SNR is developing features tapered rollers, where the main component (metal) has been replaced with ceramic, which explains why we're calling it a hybrid. This patented innovation has the potential to save around 15% off the bearing's total weight.

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.
