About NTN Deep Groove Ball Bearing

  • Deep groove ball bearings are very widely used.
  • A deep groove is formed on the inner and outer ring of the bearing enabling the bearing to sustain radial and axial loads in either direction as well as the complex loads which result from the combination of these forces.
  • Deep groove ball bearings are suitable for high-speed applications.
  • When two or more deep groove ball bearings are used in combination and mounted adjacent to each other a duplex set (D2) should be used.
  • Duplex bearings (D2) utilize controlled tolerances to more evenly distribute the loading between the individual bearing rows which improve the overall performance of the assembly.
  • In addition, to unsealed and unlubricated "open" bearings, NTN provides deep groove ball bearings that are pre-lubricated with grease and enclosed by seals or shields.
  • "Lubrication" for a list of some of the greases which can be used.
