CRM - Captive Rubber Mountings and Hangers
Size CRM2

For Marine and Heavy Industrial Applications

A universal captive rubber mounting for supporting, hanging, anchoring and guiding pipework and 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).
• 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. This material is a low thermal conductivity rigid insulation material.
• 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.
