New Marsh Mellow springs, now available from Air Springs Supply , are fabric-reinforced solid rubber vibration isolators designed for quiet isolation of machinery vibration and for general shock absorption through a variety of industries. The cylindrical springs, developed by Firestone, are used internationally as an alternative to metal coil springs for applications involving building, construction, computer, electrical and electronic equipment including motors, gearboxes, compressors, conveyors, materials handling machinery and shock absorbers.  

Vibration occurs in all rotating or reciprocating machinery as a result of forces generated within it. Often it is caused by imbalances in rotors, bearings, springs and gears as vibration migrates from the source to surrounding structures and wear-prone components. If vibration is left unchecked it can cause energy waste, operator fatigue and nuisance, bearing failures, metal spring cracking and collapse, as well as interference with nearby electrical equipment. Marsh Mellow vibration isolators are a simple, robust and effective means of solving these vibration and isolation problems.  

The Marsh Mellows are constructed with a solid rubber core with a hollow centre, and several plies of fabric-reinforced rubber as an outer cover. These plies give the springs stability and the ability to support greater loads while maintaining its cylindrical shape.  

Mr Simon Agar, General Manager for Marsh Mellows’ Australian distributor, Air Springs Supply Pty Ltd says; “Marsh Mellow springs are quiet in operation, unlike steel springs which readily transmit high frequency structural noise and often suffer from coil chatter. A failing coil spring may crack, causing fragments of the coil to damage equipment, resulting in expensive downtime. This problem is eliminated with Marsh Mellow springs, which are tolerant of overload and, if they ever do fail, do not fail catastrophically.”  

“The quiet performance of Marsh Mellows – and the fact that they resist water and grit – means they are ideal for applications where high levels of workplace safety and hygiene are essential. Such applications can range from metals and minerals plants through to primary processing, timber and paper and food and beverage.  

“The low natural frequencies of Marsh Mellow springs mean they provide excellent isolation of forced frequencies in the range of 800-1200 cycles per minute (13-20 Hz). Their high load capability means fewer springs may be needed in an application, resulting in less overall cost,” added Mr. Agar.  

Marsh Mellow springs are maintenance-free. They have no moving parts and require no lubrication. Their rubber and fabric-reinforced construction is corrosion resistant for a durable, long life. The vibration isolators have been proven in the harsh damp and corrosive environments.
