SN Mount
The SN is a rubber-metal anti-vibration mount made by AMC Mecanocaucho, designed primarily for marine engine isolation where the engine excitation frequency is less than or close to 1,000 rev/min. It supports marine propulsion systems and other multi-application machinery requiring low-frequency vibration attenuation.
Specifications
- Load capacity (180 kg variant): 180 kg; deflection 9 mm; 45 Shore A
- Load capacity (240 kg variant): 240 kg; deflection 8 mm; 60 Shore A
- Rubber hardness options: 45 Shore A, 60 Shore A
- Weight: 2.616 kg (both variants)
- Target excitation frequency: less than or close to 1,000 rev/min
Applications
Primarily used for marine engine mounting where low engine speeds produce excitation frequencies at or below 1,000 rev/min. Also suitable for other industrial equipment requiring vibration isolation at low excitation frequencies.
Frequently asked questions
Why is the SN specified for engines below 1,000 rev/min?
At low rotational speeds, engines generate low-frequency excitations that require a mount with appropriate stiffness and deflection characteristics. The SN is tuned to isolate these low-frequency vibrations effectively in marine applications.
What rubber hardness options are available?
Two variants are offered: 45 Shore A with a 180 kg load rating and 9 mm deflection, and 60 Shore A with a 240 kg load rating and 8 mm deflection.
