Use medium

The air spring can be filled with compressed air, nitrogen or water. If water is used to fill the air spring, an anti-rust layer must be added to protect the end cover. If the air spring is filled with liquid, the following characteristics are achieved:

Reduce the volume of gas inside the air spring, thereby increasing the natural frequency of the air spring.

Since water is an incompressible medium, accurate positioning can be achieved.

Use temperature

The use temperature range of standard industrial rubber air springs: -40℃～+60℃.

According to the needs of different working environments, different types of rubber are used with a use temperature range of: -25℃～+90℃.

Working pressure

  1. Most standard industrial rubber air springs have a working pressure of 0.5MPa;
  2. The maximum operating pressure does not exceed 0.7MPa;
  3. The maximum pressure of multi-layer rubber air springs exceeds 1.25MPa;
  4. Experimental data show that the maximum bursting pressure (allowed for use) is greater than 2.0MPa;
  5. The bursting pressure of a standard rubber air spring should be 2.5 times the normal operating pressure. For example, if the normal operating pressure is 0.5MPa, the bursting pressure value is set to 1.25MPa. If used according to this value, it is relatively safe. Please note that the bursting pressure of a rubber air spring decreases with the increase in the number of bends, which is determined by two factors: the maximum elongation height and the internal pressure at this height.
