Industrial Air Spring Rubber Bellows
Core Functions
Load bearing: By filling the inside with compressed air, the compressibility of air is used to bear the weight of the equipment or structure.
Shock absorption/vibration isolation: The elasticity of air is used to effectively absorb and isolate the impact and vibration from the operation of the equipment itself (such as vibrating screens, punching machines) or the external environment (such as uneven ground).
Leveling/height adjustment: By changing the internal air pressure, the support height can be accurately adjusted to keep the equipment or structure level.
Provide flexible support: Compared with metal springs or rubber pads, air springs provide lower stiffness and softer support, with better vibration isolation effect and lower natural frequency.
Key Structures and Materials
Rubber bladder: This is the main body of the bladder, which is made of multiple layers (usually 3-5 layers) of high-performance synthetic rubber (such as natural rubber, chloroprene rubber, nitrile rubber) and high-strength cord layers.
Rubber layer: Provides air tightness, weather resistance, oil resistance, chemical resistance, ozone resistance, wear resistance and certain elasticity.
Cord layer: Embedded between rubber layers, usually made of polyester, aramid or steel wire. This is the "skeleton" of the bladder, bearing most of the load, and determines the bladder's load-bearing capacity, pressure resistance and shape stability. The arrangement angle of the cord (usually close to 54.7°) has an important influence on the stiffness and deformation characteristics of the bladder.
