Firestone's Marsh Mellow Vibration Isolators introduce an innovative approach to utilizing rubber's superior isolation properties. These isolators feature a unique construction with a solid rubber core, a hollow center, and a fabric-reinforced body. The versatility in design is attributed to the adjustable variables of this construction, allowing the Marsh Mellow springs to offer exceptional design flexibility.
Firestone Industrial's Marsh Mellow™ spring is a fabric reinforced rubber cylinder developed by Firestone Industrial Products in the early 1970's. Firestone's Marsh Mellow™ Springs have long time been a subject of interest in the vehicular suspension and industrial application fields because of their reliability, corrosion resistance, low cost, and basic simplicity. There are many advantages to using Firestone's Marsh Mellow™ Spring:
Constant Vibration Isolation with Changing Loads
The Marsh Mellow's variable spring rate allows a nearly constant natural frequency with changing loads. This results inconsistent vibration isolation with variable loading.
High Load Carrying Capacity
Due to the Marsh Mellow Spring's higher deflection capabilities and load carrying influences of the fabric reinforcement, it can carry a greater load compared to all rubber parts of similar modulus and dimensions.
Excellent Vibration Isolation
Low natural frequencies provide excellent isolation of forced frequencies in the range of 800-1200 cycles per minute (13-20Hz).
Lateral Vibration Isolation
The lateral spring rate of a Marsh Mellow spring can sometimes be less than the vertical spring rate, this results in a lower lateral natural frequency. Marsh Mellow springs provide better vibration isolation in all degrees of freedom.
Compact Overall Size
The ability to support greater loads and maintain a cylindrical shape results in a smaller overall size of the Marsh Mellow spring compared to an all rubber spring with identical load capacity. This is important when considering an application with a small design envelope.
Corrosion Resistant for a Durable, Long Life
Due to its rubber and fabric reinforced construction, the Marsh Mellow spring has been proven in the damp and corrosive environments of mines and mills where a standard coil spring will fail.
Does Not Bottom-Out
Due to the rubber construction, Marsh Mellow springs do not bottom-out like coil springs. Bottoming-out under overload or surge load sends a large amount of stress to all of the machine's components.
Eliminates Downtime and Potential Damage to Machinery
When a coil spring fails, it will often crack allowing fragments of the coil to damage equipment. This problem is eliminated with the rubber construction of Marsh Mellow springs. Additionally, Marsh Mellow springs exhibit exceptionally high overload characteristics and usually do not fail catastrophically, offering some support even during failure.
Increased Stability at Higher Percentages of Compression
Rubber is an incompressible fluid which will flow to the path of least resistance. In a Marsh Mellow, as the height compresses, the fabric reinforced rubber plies pantograph and the diameter grows. This supports the rubber core laterally even at 30-40% compression.
Effective Noise Reduction
Marsh Mellow springs reduce structurally transmitted noise caused by vibration. Marsh Mellow springs are quiet, unlike steel springs which often suffer coil chatter and readily transmit high frequency structural noise.
Low Cost
The Marsh Mellow spring's high load capability means fewer springs may be needed in an application, resulting in less overall cost.
Maintenance Free
Marsh Mellow springs have no moving parts. No maintenance or lubrication is required
