    Properties

    • Design:
      • on one side an expanding shaft with tapered clamping element
      • on one side a clamping hub
      • backlash-free, blind mate press-fit connection (glass-fiber reinforced plastic)
    • Temperature range: -30° to +110° C (-22° F to +230° F)
    • Tolerance: On the hub/shaft connection 0.01 to 0.05 mm.
    • Service life: These couplings have an infinite life and are maintenance-free if the technical ratings are not exceeded.
    • Material:
      • bellows made of highly flexible high-grade stainless steel
      • clamping hub aluminium
      • expanding hub and cone (steel)
    • Speeds:
