  • it consists of a thick-walled outer ring with a gothic profiled raceway which results in a 2-point contact in the contact zone to the raceway
  • the inner ring and two ball-cage assemblies with plastic cages are similar to a double row angular ball bearing and can be mounted on an axis
  • supports either high radial or high axial forces in both directions
  • 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
  • seal: non-contact gap seal on both sides made of a profiled sheet steel disc (ZZ / 2Z) (former KDDU) for higher speeds than with rubber seal
  • In addition to this article, we can also offer bearings of the brands FAG, KOYO, NSK, SKF, SNR, etc. on request.
