Replaces Firestone 7145 Goodyear 2B14-354 Contitech FD 530-22 374 Product information Truck / Trailer Air springs are widely used on trucks and trailers. They are fitted in the front, rear and tag axle in case of necessity. Air springs protect load of the vehicle and give comfort to driver by eliminating adverse road conditions. Bus In Europe and USA, all buses are fitted with air springs, whereas, in many other countries the usage of air suspension systems is increasing. Buses benefit the great advantages of air springs to achieve consistently high travelling comfort. This application generally involves two air springs being fitted to the front axle and four to the rear axle in the buses. Air springs are developed according to technical specifications, such as load capacity and spring deflection. Rolling lobe air springs With conical beads Depending on their weight, they achieve high strokes resulting high comfort without a major change in diameter. This high stroke advantage of conical bead rolling lobe air springs enable the loading/unloading and assembling/disassembling operation easier for these vehicles. The conical sealing surfaces of these springs make them to be reused when the air springs bellows are replaced. With clamping beads Rolling lobe air springs with clamping beads differ from the ones with conical beads by the method of fixing. The fixed connection prevents the air springs to be detached from the plate even under the excessive movement connections. Rolling lobe air springs with clamping beads are supplied by Airtech as a complete unit with its pistons, plates and the internal bumpers, where necessary assembled as a complete unit.
