MARSH MELLOW SPRINGS Increase productivity and reduce downtime with Marsh Mellow Fabric & Rubber Springs. Long life, simple mounting, fast replacement time, and virtually maintenance-free operation boost machine availability for greater productivity. Marsh Mellow Springs cannot break, trap particles, corrode, or bottom-out. Each spring features a biasply fabric wrap for dependability and uniform performance. The variable rate/constant frequency of the spring allows each spring size to accommodate a wide load range and perform consistently, whatever the load. Tough, quiet Marsh Mellow Springs are a great new solution to those same old isolation problems. Replace old-fashioned metal springs with fabric & rubber springs for long-lasting, low-cost isolation performance. Specify Marsh Mellow Springs by Firestone. Old Problem Isolation Noise Gallop through resonance Short spring life Corrosion, abrasion Surge loads Bottoming-out High maintenance costs Lengthy replacement downtime Limited space for high-load spring Metal fatigue and breakage Complicated mounting Construction Unique construction elements are the secret of the spring's design flexibility. The solid rubber core with hollow center, bias-ply fabric wrap, and tapered ends, may be varied and combined to meet specific load and performance requirements. Performance One spring size meets the needs of a wide range of load applications. Surge loads are handled without unbalancing the system, due to the variable rate/constant frequency of Marsh Mellow. Marsh Mellow Springs will not bottom-out under overload or surge load, or become unstable under uneven loads. Effective deflection A typical 6" OD x 1" ID x 10" length spring provides the same natural frequency over a 2000-5000 lb. load range for uniform performance. Mounting Installation is simple, fast, and uses a minimum of space. Normally, a spacer and two pins are all that's required.
