Fabreeka pad is the original preformed fabric reinforced, elastomeric pad developed in 1936. The properties of the Fabreeka cotton duck pad are exceptionally suited for impact shock control, vibration isolation and structure-borne noise insulation. Fabreeka pad can be used as a bearing pad as well as for isolation washers, bushings and OEM parts.
Fabreeka pad has been used for over 80 years for mounting heavy machinery where absorption of impact shock is required. Meeting or exceeding MIL-C-882 and MIL-E-5272 specifications, Fabreeka pad prevents cracking and flaking of concrete, eliminates the need for grout and prolongs the life of both machines and structures. Each preformed fabric pad made by Fabreeka is scientifically constructed to give years of service under the most severe operating conditions.
When considering vibration isolation, usually more than one disturbing frequency is present in a machine. As a general rule, an attempt should be made to isolate the frequency producing the largest vibration amplitude, while avoiding resonance with the other disturbing frequencies. Fabreeka’s fabric reinforced elastomeric material, with its resilience, minimal deflection and high strength, often serves as a more practical vibration isolator than softer materials.
Very effective, flexible and tough
Fabreeka’s part in isolating noise is one of reducing structure-borne noise. Fabreeka reduces mechanical vibrations which can be converted to air-borne noise. When isolating structure-borne noise, it is essential that all conductive paths of vibration be blocked. Therefore, Fabreeka pads, washers and bushings are required to completely break the metal-to-metal contact between the isolated unit and its support.
Fabreeka bearing pads were first used as a bridge bearing and are commonly used as a structural bearing element accommodating surface irregularity and rotations between load bearing faces. The preformed fabric pads can also be provided with a Teflon® surface for use in expansion bearings and pipe slides.
Depending upon the size and thickness, Fabreeka pad can ultimately withstand loads up to 10,000 psi. Normally, compressive stresses are designed not to exceed 2,000 psi to extend service life and reduce permanent set
