VMC Group LD Series Large Deflection Mid-Frequency Isolators provide both shock and vibration protection for a variety of applications. These isolators can attenuate a 15.0 g, 11-millisecond shock to 10.0 g; and a 30.0 g, 11-millisecond shock to 16.0 g. The LD Series Isolators are ideal for use in applications where vibration and shock are a concern such as propulsion, guidance, radar, sonar and other sensitive systems.
Two different elastomeric element types are available in The LD Series. The standard elastomer that offers an operating temperature of -20⁰F to +180⁰F provides effective isolation in most applications. The optional polybutadiene version is used in situations when operating temperatures may drop as low as -65⁰F. Both versions are excellent when high amplitude vibration inputs are expected or large shock deflections are needed. Both versions also resist oils, ozone and most solvents - providing optimum resilience in difficult conditions.
No special tools are required for installation. The central isolators are not inherently failsafe. These isolated systems do require a suitable means of restraint.
Features & Benefits
