Features

  • designed as hybrid deep groove ball bearing: rolling elements made of ceramic, inner and outer ring made of stainless steel
  • cage material: plastic; the low weight and the elasticity of the plastic have a positive effect on the sliding and emergency running properties as well as the shock resistance; suitable for quiet running
  • lighter than comparable deep groove ball bearings with steel balls as rolling elements; ceramic balls have a current-insulating effect; withstands higher speeds and has a high wear resistance
  • thin section bearing with ultra-thin, square cross section
  • suitable for space-saving installation in radial and axial directions
  • suitable for extremely high speeds compared to deep groove ball bearings with a larger cross section
  • extra light series with compact dimensions and low weight
  • suitable for radial loads and light axial loads in both directions
  • offers high running accuracy, quiet running and very high speeds
  • seal: non-contact gap seal on both sides made of a profiled sheet steel disc (ZZ / 2Z) for higher speeds than with rubber seal
  • good fixed bearing property, but can also be used as a floating bearing, each in both directions
