Technical Guides

Top/Bead Plate: Connects the Air Spring bellow to the vehicle frame.
Bumper: Restricts the Air Spring and ensures emergency operation functionality.
Flexmember: the bellow is a vulcanized rubber construction, consisting of a rubber internal layer, a layer of reinforced material and an external rubber layer. This construction gives the bellow strength and durability.
Clamping Plate: Connects the Air Spring and the piston and protects leak integrity.
Can be vulcanized onto the product or connected manually as required.
Piston: Connects the Air Spring and the axle, can be steel or composite.
Girdle Hoop: Stabilizes the Air Spring.
Bottom Plate: Connects the Air Spring and axle.

Check all airlines for leaks.
Check air springs have enough clearance when inflated.
- Mis-aligned suspension parts rubbing in the air spring will cause the diaphragm/bellow to wear away.
Check the original specification for the suspensions' ride height as in fig 1.
- This should be maintained to protect the air springs and shock absorbers from over extension.
Check the diaphragm/bellow for irregular wear, natural wear or outside interference.
Clean the diaphragm/bellow with a non-petroleum based solution.
Check the piston, on rolling lobe type air springs, for sharp edges or settlement of dirt or foreign bodies.
Check shock absorbers for over extension, bush wear and fluid loss.
- If the unit can be easily compressed or extended it will not function correctly.
- If the vehicle has recently been in use the shock absorber should be warm to touch, if this is not the case the unit may need to be replaced.
Check all torque settings are to original specification.
Check height control valve function.
Mounting fixing bolts and nuts should be also be replaced when fitting new air spring.

Troubleshooting

The information below is designed as a guide to the most common reasons of air spring failure.

Before installing a new air spring, it is recommended to carefully examine the cause of failure. If the cause is not rectified, this will result in the failure of the newly installed air spring.
