7210 - NTN


Angular contact ball bearings, pressed steel cage

The single row angular contact ball bearing is designed to withstand combined loads with a predominant axial component. Installed in opposition with another bearing of the same type, it guarantees high mounting rigidity.

The NTN-SNR range is available in several variants: 30° or 40° angles, polyamide, pressed steel or solid brass cages, universal pairing available, clearances or preloads, etc.
