NTN 6007N bearing with snap ring groove

NTN deep groove ball bearings are suitable for high speed applications, they are widely used bearing type. Except for the unsealed bearing, ball bearings have greased sealed inside (sealed or shielded) and bearings have a snap ring that simplifies structure around the bearing and design. 

The suffix and designation of NTN deep groove ball bearing,
ZZ: shielded type, non-contact type
