BELLOWS CONSTRUCTION An air spring is a carefully designed rubber fabric bellows which contains a column of compressed air The rubber bel lows itself does not provide force or support load This is done by the column of air Firestone air springs are highly engineered elastomeric bel lows with specially designed metal end closures Our standard two ply air spring bellows is actually made up of four layers a An inner liner of calendered rubber b One ply of fabric reinforced rubber A second ply of fabric reinforced rubber with the cords at a specific bias angle to the first ply d An outer cover of calendered rubber Many of our air springs are also available in high strength con struction for higher pressures see page 14 for more detailed information In this case there are four plies of fabric rein forced rubber with an inner liner and outer cover FIRST PLY INNER LINER The two ply air spring is standard Where high strength con struction is available it is so noted in the selection guide page 32 on the individual Data sheets and in the index page 107 If the high strength style number is omitted then it is not currently available in that particular part Each air spring bellows is identified by a style number This style number is molded into the bellows during the curing or vulcanization process Examples would be 16 22 313 1T15M 6 etc This identifies only the rubber f
