AT
The AT anti-vibration mount is a rubber-metal isolator from AMC Mecanocaucho designed for medium to high frequency vibration isolation in industrial plant and equipment. The rubber section is fully bonded to two concentric tubular metal parts and operates in shear mode, providing a radial to axial stiffness ratio of 4:1 for reliable horizontal stability.
Specifications
- Operating mode: Rubber in shear
- Radial to axial stiffness ratio: 4:1
- Rubber hardness grades: Soft (A 45 Shore), Medium (B 60 Shore), Hard (C 75 Shore)
- Load range: 6 kg to 2,600 kg depending on size and hardness grade
- Attachment: 3 or 4-hole flanged outer metal part, depending on size
- Inner metal: Plain tube design
- Fail-safe installation: Top and bottom washers provide progressive stiffness and overload rebound control
Applications
Engines, piston compressors, presses, electric transformers, mobile units, and machines mounted on concrete buttresses where medium to high frequency vibration isolation is required. The 4:1 stiffness ratio makes the AT suitable where lateral stability is important alongside axial isolation.
Frequently asked questions
How does the stiffness ratio affect performance?
The radial to axial stiffness ratio of 4:1 means the mount resists horizontal forces four times more firmly than vertical forces, which helps keep machinery stable under transient lateral loads while still providing axial vibration isolation.
How do I choose between the three hardness grades?
Hardness grade is selected based on the static load of the equipment. Soft (A 45 Shore) suits lighter loads from approximately 6 kg, Medium (B 60 Shore) covers mid-range applications, and Hard (C 75 Shore) is rated up to 2,600 kg for the largest mount sizes.
What is the purpose of the flanged outer metal part?
The flanged outer metal part provides the attachment interface to the support structure. The number of attachment holes varies by mount size, allowing secure bolting to a range of base configurations.
