Deep Groove Ball Bearings

DUNLOP Single row deep groove ball bearings, commonly known as 'popular metrics', are rigid non-separable radial bearings and are the most common bearings, used in a wide range of applications from agricultural equipment to printing machinery.


They are designed to carry both axial and radial loads.


Single row deep groove ball bearings are superior in speed rating to any other type of rolling element bearings. They are by far the most popular rolling bearing type and are classified as follows:


  • Miniature ball bearings - including 3.175 mm inner bore diameter
  • Extra small ball bearings - over 3.175 mm including 9.525 mm inner bore diameter
  • Deep groove ball bearings - over 9.525 mm inner bore diameter
  • Available in both metal shielded and rubber sealed versions
