Product description:

  • Deep groove ball bearings are particularly versatile
  • They are simple in design, not removable, suitable for high to very high speeds and are very robust in operation, requiring little maintenance
  • Deep raceways and close contact between raceways and balls make deep groove ball bearings suitable not only for radial loads, but also for axial loads in both directions, even at high speeds
