  • RoHS
Exhibits excellent anti-vibration effect with a structure with a rubber diaphragm
The PSD type air spring is a special air spring in which a rubber diaphragm is installed in a metal cylinder, and has excellent anti-vibration performance. In addition, it is an air spring that is low in height, easy to use, and easy to install and maintain.

Performance/Features

Excellent anti-vibration effect

At maximum load, the natural frequency is 3 to 4 Hz, demonstrating anti-vibration performance close to PSB type air springs.

Excellent sound insulation

It can insulate the surging phenomenon seen in coil springs and provide soundproofing effects.

Damping effect of rubber

The rubber film is relatively thick, and the rubber itself has a damping effect.

Highly safe

Side walls are made of metal, which increases safety in the event of a contact accident.

Low product height

The height of the product is the same for all sizes and is designed as low as 90mm. For this reason, the height of the equipment is not so high, and it is possible to use different sizes together.

Easy level adjustment

This product is an air-sealed type, and a tire valve (for automobiles) is attached to the main body to seal the air. Air can be easily filled with an optional air chuck (air sealing tool).
In addition, air can be easily released by pressing the core of the tire valve, making it easy to adjust the level.

Easy to install and maintain

The internal stopper allows the device to be supported even without air, making it easy to install and maintain.

Precautions for use

1.  Never inject air when the air spring is unloaded.
2.  Be sure to remove the air before removing the air spring from the equipment or moving the equipment.
3.  Be careful not to damage the diaphragm of the air spring during installation and use.
     Install a protective cover if there is a risk of foreign matter coming in contact with the diaphragm or tire valve.
4.  The ambient temperature for use should be -20°C to +60°C.
     In environments exceeding 40°C, the life of air springs may be shortened.
5.  Be careful not to allow acids, alkalis, organic solvents, lubricating oils, etc. to adhere to the diaphragm.
     In the unlikely event that it adheres, wash it with water immediately.
6.  Use the air spring height within the range of 90±6mm.
7.  If there is a scratch reaching the reinforcement cord on the diaphragm or an abnormal bulge, replace it immediately.
8.  Do not raise the pressure above 0.5 MPa even during the air charging process.
     At maximum load, the pressure at standard height 90mm is 0.45MPa.
9.  There may be brown discoloration near the valve insertion port, but it is not rust.
     It is a sealing material that prevents air leakage. Never wipe off. It may not work properly.
     Ten. For anti-vibration purposes, do not use air springs for equipment that meets the following conditions.
     ①: When the operating speed (or operating stroke speed) of the device is close to the natural frequency of the air spring, 3 to 6 Hz.
     This is the case, for example, for presses below 500 rpm.
     ②: For devices whose rotational speed rises and falls very slowly when starting and stopping, and whose resonance state continues for a long time.
     ③: Not applicable to (1), but the excitation force of the equipment is strong, and as a result, the amplitude of the air spring becomes excessive at the normal rotation speed.

Main use

Anti-vibration for industrial machinery

Air compressors, blowers, refrigerators, generators, printers, transformers, and other equipment

* Basically, it can be used for the above equipment, but it may not be used for some equipment and under some usage conditions. See usage notes.
In addition, additional mass, dampers, stoppers, etc. may be required in actual use.

Vibration isolation for precision equipment

balances, surface roughness meters, roundness meters, three-dimensional measuring instruments, other precision measuring instruments, testing machines
