An air spring is an inflatable rubber bladder that uses the elasticity of compressed air within a confined space to support loads and absorb shock and vibration. While its operating principle is similar to that of a car tire, its design and purpose are specifically engineered for industrial applications.

• Air Bladder: Made of high-quality natural rubber reinforced with cord layers
• Cover Plates: Upper and lower metal pressure plates
• Operation: Compressed air injection increases internal pressure, generating support force and elastic deformation

• High-Strength Rubber: Provides excellent flexibility and fatigue life
• Cord Reinforcement: Multiple layers of high-strength cord (nylon, polyester, or aramid) prevent over-expansion
• Specialized Formula: Offers oil resistance, airtightness, and aging resistance

• Capable of withstanding high-speed reciprocating compression (hundreds of times per minute)
• Excellent airtightness ensures stable pressure maintenance
• Oil-resistant formula suitable for lubricated environments
• Long-term durability under specified temperature ranges (-30°C to +70°C)

• Installation space and required stroke
• Operating pressure range (2-7 bar)
• Air inlet thread size compatibility

• Rubber bladder rupture from overcompression or aging
• Air leakage due to seal failure or bladder damage

• Regularly inspect for surface cracks, scratches, or bulges
• Operate within specified pressure and stroke ranges
• Maintain dry, clean air source to prevent moisture contamination
