Fabreeka Pad as Shock Control
Fabreeka pad is the original fabric reinforced, elastomeric pad developed in 1936. The properties of the Fabreeka pad are exceptionally suited for the reduction of impact shock.
Fabreeka pad has been used for over 70 years for mounting heavy machinery where absorption of impact shock and isolation of transmitted vibration is desired. Fabreeka pad prevents cracking and flaking of concrete, eliminates the need for grout and prolongs the life of both machines and structures. Fabreeka pad is scientifically constructed to give years of service under the most severe operating conditions.
Associated Applications:
Industrial Machinery
Metal Forming
Military/Defense
Mining
Pulp & Paper
Steel
Key Features/Benefits:
- Depending upon the size and thickness, Fabreeka pad can ultimately withstand loads up to 12,000 psi. Normally, compressive stresses are designed not to exceed 2,000 psi to extend service life and reduce permanent set.
- Fabreeka pad has a relatively high damping rate of 14% of critical, twice the value of damping for natural rubber and unreinforced elastomers.
- Fabreeka pad has very high energy storage per unit volume, which makes it ideal for shock isolation.
Technical Specifications:
One of the advantages of the reinforced, laminated design is the reduction of additional deflection due to creep under static load. Creep is limited to approximately 5% of the original pad thickness. When stresses are removed, the permanent set is also limited to approximately 5%.
Fabreeka pad meets or exceeds the MIL-C-882 and MIL-E-5272 military specifications.
Fabreeka pad is impervious to most oils and is resistant to the effects of steam, water, mildew and brine. The effective temperature range is -65°F to 200°F.
The durometer of the Fabreeka pad is 90±5 (Shore A).
