– Natural frequency (vertical and lateral) under nominal load: 4 to 5.5 Hz.
– Maximum displacement under shock: 75 mm* all in directions.
V1B VHD 75 Low Loads
Elastomer isolators designed for acoustic isolation and shock protection.
Vibration and noise isolation systems.
Elastomer isolators designed for acoustic isolation and shock protection.
– Natural frequency (vertical and lateral) under nominal load: 4 to 5.5 Hz.
– Maximum displacement under shock: 75 mm* all in directions.
The SANDWICH mounting comprises one or more layers of elastomer bonded to flat, parallel metallic plates. These mountings may be cylindrical or rectangular. They are designed to withstand very high compressive loads. The range of mechanical characteristics is governed by the hardness of the rubber and the number of intermediate metallic plates.
These mountings can support compression from 20 to 100 bars.
The metal plates usually receive a phosphate anti-corrosion treatment.
The elastomer is polychloroprene which provides a high resistance to atmospheric exposure.
The 22000 mount is made of two parts of elastomer bonded to a central tube.
– Interior reinforced: cylindrical tube.
– Elastomer: chloroprene. Range of five different stiffnesses.
– Better than 90% isolation at 1.500 rpm(25 Hz).
– Constant height over wide load range.
– Stabilised characteristics during Service Life.
– Simple to fit.
– 400 hours protection against salt spray*.
– Design.
These parts are usually supplied in VHDS (very high density silicone) rubber and the full reference should include:
– the letter S,
– the appropriate grade which corresponds:
– to the youngs modulus of the rubber under static compression in accordance with ASTM D945 (ref. 33 to 77),
– or to the stiffness measured on a part (ref. 16 to 25).
