NTN large bore bearings–A very serious problem that the contact surfaces of NTN large bore bearings subject to is repeated heavy stress, while they still must maintain high precision and rotational accuracy during running. In order to accomplish this, the raceways and rolling elements of all large NTN bearings are all made of material that has high hardness, is resistant to rolling fatigue, is wear resistant, and has good dimensional stability.

Whether large NTN roller bearings or ball bearings, they are all have to stand greater stress, therefore, special materials must be used. For all NTN bearings, steel low in oxygen content and non-metallic impurities, then refined by a vacuum degassing process as well as outside hearth smelting, is used. For bearings requiring especially high reliability and long life, steels of even higher in purity, such as vacuum smelted steel (VIM, VAR, CEVM) and electro-slag melted steel (ESR), are used.

In addition, all NTN large bore bearings distributed by SSHB are assured to be brand new, company sealed, non tampered, original bearings. The diameters of them are large enough to 750 mm, satisfying the majority customers’ requirements.
