Captive Rubber Mountings and Hangers

Size CRM2

A comprehensive range of steel spring and rubber hangers offering the designer a choice between low frequency vibration isolation or optimum performance at higher audible frequencies if noise control is of paramount importance.

Wide load ranges and fixing requirements are catered for. Specialist hangers combining steel springs and rubber elements are available and also higher deflection springs if required.

Design Features:
  • Tested at 40°C ambient with eyebolt at 400°C (300 mm drop rod and turnbuckle fitted) resulted in only 2°C temperature rise at inner rubber surface.
  • Rubber insert is moulded in three variants 55, 65 and 70 IRHD (International Rubber Hardness) from polychloroprene neoprene which retains its mechanical characteristics at high temperature.
  • Rubber insert provides excellent high frequency attenuation performance.
  • Unit remains captive and fail-safe whether used as a supporting mount or hanger.
  • Unit can be bolted to structure or supplied fitted with a base plate to permit fixing by welding.
  • Optional heat insulation pad 100 x 100 x 19 mm thick available for use with mounting.
  • The hanger is supplied complete with turnbuckle and eyebolt, optional 1 m long drop rod available.
  • High transverse/axial stiffness ratio ideal for use as a 'flexible anchor'.
  • Capable of 15° angular misalignment.
  • Optional soleplate available which can be welded to the structure.

 

Typical Applications:
      • Marine Exhaust Systems.
      • Industrial Exhaust Systems.
      • Ductwork and Attenuators.
      • High speed rotating machinery.
      • Shock mount for control cabinets, instrument racks etc.
