All above specifications are meant to be used for basic comparison and information purposes only. Please verify with the above manufacturers directly.
In order to have been selected for this list the above mentioned products would be considered to be of the highest quality. When engineers specify vibration control or thermal break products or brands they generally add the “or approved equivalent” option. Typically lead time and pricing become determining factors once the engineer on record has verified the selected product meets the design criteria.
Benchmark makes no further representations.
The above comparison table is meant to assist with identifying additional approved alternative products. For more detailed and verified specifications please contact the respective above manufacturers directly.
MIL C 882 anti vibration pad is the original fabric reinforced, elastomeric pad developed in 1936. The Vibsorb MIL C 882 pad conforms to the specifications for MIL-C-882 cotton duck, fabric reinforced pad. The properties of the MIL C 882 anti vibration pad are exceptionally suited for vibration isolation and structure-borne noise reduction.
MIL C 882 anti vibration pad has been used for years for mounting machinery and equipment where absorption of impact shock and isolation of transmitted vibration is desired. MIL C 882 pad is also used to provide structural damping and to break the vibration transmission path. MIL C 882 anti vibration pad is scientifically constructed to give years of service under the most severe operating conditions.
Depending upon the size and thickness, MIL C 882 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.
Vibsorb MIL C 882 pad has a relatively high damping rate of 14% of critical, twice the value of damping for natural rubber or unreinforced elastomers.
Natural Frequency as low as 12 Hz.
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%.
MIL C 882 anti vibration pad meets or exceeds the MIL-C-882 and MIL-E-5272 military specifications.
MIL C 882 anti vibration 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 MIL C 882 anti vibration pad is 90±5 (Shore A).
