CRM - Captive Rubber Mountings & Hangers

Size CRM2

A universal captive rubber mounting for supporting, hanging, anchoring and guiding pipework & ductwork, particularly exhaust systems on board ship.

Designed specifically for use in high ambient temperature conditions for the control of vibration throughout the audible frequency range.


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..
