Goodyear Bellows 578-93-3-100 Triple Convoluted Rubber Air Spring
for Replacement
Product Introduction
3B5601 AIRSUSTECH Air Spring. AIRSUSTECH air springs bring the
productivity and service life of your trucks, trailers, and buses
to a whole new level. The bellows air spring provides constant
horizontal traction and delivers trouble-free service. The AIRSUSTECH airbag protects cargo and provides horizontal
traction with long-term service. The bellows air spring offers a
quiet and cushioned ride experience, and due to reduced vibration,
it has a longer service life than steel springs. Drivers enjoy more
comfortable rides with reduced fatigue, keeping them more alert.
Additionally, cargo is better protected from shocks and vibrations.

How to Determine AIRSUSTECH 3B5601 Airbag Compatibility?
1. Determine the key parameters:
- Dimensions: Precise inner diameter, outer diameter, length,
installation dimensions (such as flange size, bolt hole location
and size, thread specifications, etc.). Must be an exact match to
the original installation location or replacement object.
- Material: The material of the bellows body, reinforcement layer (if
any) and end connections (flanges, threaded joints, etc.). This
determines its chemical resistance, temperature range and wear
resistance.
- Working pressure: Maximum allowable working pressure and burst
pressure. Must be higher than or equal to the maximum working
pressure in the application system, and consider the safety factor.
- Working temperature: Minimum and maximum continuous operating
temperature range. Must cover all temperature conditions in the
application environment.
- Media compatibility: Clearly specify which fluids it is designed
for (hydraulic oil, lubricating oil, air, water, specific
chemicals, etc.). Must ensure full compatibility with the actual
media flowing in the system to avoid material swelling, corrosion
or degradation.
- Dynamic performance: If it is used to absorb vibration,
displacement or compensate for thermal expansion and contraction,
you need to understand its allowable axial/lateral displacement,
angular deflection and fatigue life.

2. Clarify the application scenario
Purpose: Where is this bellows used? For example:
- Engine (crankcase ventilation, EGR system?)
- Turbocharger (intake pipe, bypass valve?)
- Exhaust system (flexible connection?)
- Hydraulic system (pipe connection, shock absorption?)
- Pneumatic system
- Industrial machinery (drive shaft sleeve, connection?)

3. Dimension measurement and comparison
Accurate measurement: If you have an old bellows that needs to be
replaced or a location that needs to be installed, use tools such
as calipers to accurately measure key dimensions:
- Inner diameter
- Outer diameter
- Total length
- Outer diameter, inner diameter, bolt hole center distance, bolt
hole diameter of flange
- Type and specification of threaded joints
