Smart fleet managers utilize top quality and thoroughly tested air springs to provide thousands of miles of smooth and safe rides. An investment in the right air springs will often outlast other maintenance items in a suspension system. Durable air springs can last years when properly understood and maintained.
Most pre-mature air spring failures are caused by improper maintenance or abuse associated with other problems with the suspension, according to Dave Vanette, manager of new business development for Firestone Industrial Products. Regularly scheduled maintenance, normally quarterly, bi-annually or every 50,000 miles, can save a fleet time and money. Vanette says routine inspections should take special note of any debris, cuts, deformities or rubs that could lead to suspension problems. Firestone Industrial Products has developed a maintenance tip list for suspension checks:
Outside diameter: Inspect the outside diameter (OD) of the air spring and check for signs of irregular wear or heat cracking.
