Properties

  • Design:
    • with flange and removable conical clamping ring assemblies on both ends.
    • the fastening screws for mounting the flange double as the removal jack screws for the conical clamping rings with intermediate tube (Series 10 without intermediate tube)
    • welded connection between hubs and bellows
  • Temperature range: -40° F to +300° C (-40° F to +572° F); reduced ratings at higher temperatures
  • Tolerance: Overall clearance between hub and shaft 0.03-0.08 mm.
  • Service life: These couplings are maintenance-free if the technical ratings are not exceeded.
  • Material:
    • bellows made from highly flexible, high grade stainless steel;

    • hubs made from steel
  • Non standard applications: Custom designs with various tolerances, keyways, materials, dimensions, etc. available upon request.
  • Properties of Bellows Coupling model BX6:
    • for high torque applications
    • compact, simple design
    • easy mounting and dismounting
    • backlash free and torsionally rigid
    • various overall lengths available
    • high misalignment compensation
