In mechanical engineering and industrial applications, air springs play a crucial role ensuring smooth and efficient vehicle operation. Air Spring Supply Company stands as South Africa’s sole distributor for Firestone Industrial Products Company.

Understanding Air Springs

At their core, air springs contain a column of air encased within a rubber bellow or sleeve. They use an air compressor to fill and empty a malleable air bladder. The primary load-bearing element is the air itself, rather than the rubber liner which primarily serves to contain the gas.

Components of an Air Spring

• Air fitting: Tapped hole through which the compressor supplies air
• Bead plate: Crimped metal plate that encloses and attaches the spring (forged steel, cast zinc or aluminium)
• Bellows: Multi-layer neoprene or rubber construction holding compressed gas
• Girdle: Metal piece separating bellows chambers in convoluted springs
• Bumper: Optional cushioning protecting the piston in case of failure
• Piston: Attached to the machinery requiring suspension, supported by enclosed air

Types of Air Springs

• Crimped convoluted bellows: Excel in vibration isolation and actuation
• Sleeve bellows: High vibration isolation, suited for linear actuation
• Rolling lobe bellows: Most prevalent in automobile suspensions

Why Air Springs Are a Smart Choice

Installation: Cost-effective with a small footprint when deflated. Maintenance: Minimal requirements with no lubrication needed. Environmental suitability: Durable for various industrial and commercial applications.
