Air Springs Supply  presents a new vibration isolation design manual featuring simple, robust and effective alternatives to metal springs when solving industrial vibration and isolation problems.
The Vibration Isolation Design Manual for Marsh Mellow springs details how and where to use the fabric-reinforced solid rubber isolators for quiet isolation of machinery vibration and for general shock absorption throughout industry.
Developed by Firestone, a world-leading producer of air springs for isolation and actuation, the cylindrical springs are used worldwide for applications involving vibration isolation in commercial and industrial buildings, construction, electrical, automation and electronic processes, process and production engineering, forestry and primary production, manufacturing, metal processing, materials handling, mining and mineral processing including conveyors, oil and gas processing, packaging, and worker safety.
Marsh Mellow springs are particularly suitable for vibration isolation of machinery such as automation technology, bin hoppers, blowers and motors, compressors, conveyors, generators, stamping equipment and vibrating screens.
Mr James Maslin, Sales and Marketing Manager for their Australian distributor, Air Springs Supply explains that Marsh Mellow springs deliver consistent performance regardless of changing loads, while offering high lateral stability and compact size. Air Springs distributes Marsh Mellow isolators and Firestone Airstroke and Airmount bellows-type air springs (also known as airbags) throughout Australia.
Incorporating both imperial and metric selection guides, the new manual also details shock absorption applications in cranes, hammers, bumpers and similar applications requiring the cushioning of a violent blow (such as conveyor stops in industries as diverse as packaging and logging).
Marsh Mellow springs range in size from the 0216 model with unloaded height of 44mm and outside diameter of 41mm through to the 0243 with unloaded height of 203mm and outside diameter of 279mm. Marsh mellow springs have been proven in the damp and corrosive environments of mines and mills where standard coil springs may suffer premature failure.
Key features of Marsh Mellow springs: 
  • Constructed of a solid rubber core with a hollow centre and several plies of fabric-reinforced rubber as an outer cover
  • Plies provide stability as well as a consistent cylindrical shape
  • Low natural frequencies enable excellent isolation of forced frequencies in the range of 800-1200 cycles per minute (13-20 Hz)
  • Quiet in operation unlike steel springs with high frequency structural noise and coil chatter problems
  • Tolerant of overload with the high load capability enabling fewer springs to be required in an application
  • Fabric reinforcement offers more lateral stability, allowing greater loads to be supported while maintaining its cylindrical shape
  • Maintenance-free design with no moving parts and no lubrication required
  • Rubber and fabric-reinforced construction is corrosion resistant for a durable, long life
