ISOLATOR APPLICATION
| Choose an air spring assembly for which the desired operating height and load are in the design height and design load range at inflation pressures between 20 and 100 PSIG. |
| Where possible, use design heights in the center of the |
| Inflate with air or nitrogen. |
What shoud we do if the air spring is corroded
As with any other metal part on a vehicle, the top plate of an air spring is subject to rust which ultimately will eat an air-escaping hole into it. And, though pistons generally are made of corrosive-resistant aluminum or composite plastic material, they are subject to pitting from salt.
The pitting eventually will wear a hole (or holes) into the rubber bellow as it slides over the piston in its normal course of operation. Road debris also can be flung against the piston, causing it to crack.
Solution:
Periodically check condition of the air spring. Check for excessive oil or water in the air supply. Check seals, avoid excessive greasing, watch for content spillage. Check for debris build up at the piston, girdle hoops, bead plate. Keep them clean. Use soap and water - never a petroleum-based cleaner.
