Features and Usage Of Convoluted Air Spring
Rubber air spring is a kind of polymer elastomer. The product has high vibration damping effect, small resonance field, long service life, good cold resistance, excellent air tightness, water resistance and electrical insulation, which is excellent Vibration reduction options.
Due to the above advantages of rubber air springs, it has been widely used in truck floating bridges, automobile air suspensions, paper machines, lifting platforms, presses, punching machines, large toys, drying equipment, sludge dewatering machines, and vibrating conveyors. , vibrating screen, air hammer vibration testing machine, casting machinery and other equipment or instruments that require stroke control or shock absorption and vibration isolation.
