Knowleage for the air spring
Though they have comparable capabilities, air springs are much cheaper than pneumatic cylinders and other springs. When deflated, air springs have a small footprint, making them easy to manipulate and connect to machinery.
Air springs tend to have low maintenance routines and some manufacturers state their air springs are maintenance-free (set and forget). Air springs do not require lubrication, nor do they have seals or guides that may become misaligned or damaged like with other springs. Indeed, the bellows of air springs are prone to dry rot, though this could take years to develop. Air springs should be stored in dry, dark areas at room temperature.
Due to its durability and simplicity, air springs are good for most industrial and commercial applications. Rubber and neoprene are susceptible to dry rot, so dehumidified conditions could shorten the service life of an air spring. Both rubber and neoprene are suitable for use in high/low temperature applications, but have considerably less heat tolerance than metal spring options. While usable up to 65°C, neoprene should not be used below -40°C, and rubber shouldn't be used in sites below -60°C.
The name air spring is a bit of a misnomer, as the bellows of the spring can also accept other types of fluids such as nitrogen, carbon, water, and anti-freeze.
Air springs are widely utilized. Commonly as actuators in amusement park rides, packaging equipment, clutch systems, conveyor belts and scissor lifts, they also act as vibration insulators in centrifuges, commercial laundry machines, measuring and weighing machinery, and textile looms. While the air spring has impacted many industries like oil, logging, construction and manufacturing, it is most prominent in the automobile industry where the air spring is used in suspensions for vehicle brands like Lincoln, Cadillac, Hummer, and Jeep.
