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.
