3B7386 characteristic:
The empty stroke air spring has the same quality as AIRSUSTECH's legendary AIRSUSTECH spring for truck and bus suspension. The use of heavy-duty suspension requires millions of kilometers of flexibility and is designed to withstand harsh environmental conditions and other harsh conditions.
A wide range of
The diameter of the idle stroke air spring ranges from 55mm to 700mm. The capacity is 100,000 pounds. The maximum stroke can reach 355mm.
No internal rods, pistons or sliding seals
In AIRSUSTECH air springs, there are no internal rods, pistons or sliding seals like many conventional cylinders, which gives AIRSUSTECH an advantage in applications where dirt or grit will erode conventional cylinder seals.
Frictionless
In the absence of a sliding seal, the AIRSUSTECH air spring does not break away from friction.
flexible
The empty stroke air spring can be used in conjunction with a variety of media (liquid or gas).
Angle ability
Without the clevis, a stroke through an arc may produce angular movements of up to 30 degrees.
Side loading capacity
Under certain conditions, free-stroke air springs are not affected by side loads. This eliminates the possibility of rod bends, nicks and excessive seal wear that are common when using conventional cylinders.
