Description
Source reliable, heavy-duty suspension performance for your commercial fleet with the genuine Contitech Air Spring Bellows, OE 6122 N. Engineered to exact original equipment standards, this professional-grade air spring replaces worn or leaking bellows on commercial trucks, buses, and heavy-duty freight trailers. Substandard aftermarket bellows suffer from premature rubber cracking, air leakage under heavy loads, and severe chassis sag. This wholesale-ready Contitech OE 6122 N air spring solves those failures directly. It utilizes high-tensile fabric reinforcement, heavy-gauge chloroprene rubber compounds, and robust composite end plates to deliver seamless height leveling, absorb aggressive road impacts, and ensure long-lasting durability in demanding transport operations.
Technical Parameters
| Category | Specifications & Technical Details |
| OE 6122 N Precision Dimensional Matching | We manufacture this air spring strictly to the ContiTech OE 6122 N specification. As a result, the upper and lower end cap hole spacing, bolt positioning, and compression height perfectly fit the original chassis bracket. |
| High-Tensile Fabric-Reinforced Natural Rubber | We combine high-density polyester cord fabric with high-pressure-resistant rubber through high-temperature vulcanization. Consequently, the air spring withstands full vehicle vertical heavy loads and dynamic extension without bulging or bursting. |
| Dynamic Load-Adaptive Pneumatic Leveling | We design the air spring to automatically adjust internal inflation volume based on real-time vehicle and cargo weight. Therefore, it maintains constant body ground clearance and suspension geometry in both empty and fully loaded conditions. |
| Superior High-Frequency Road Vibration Isolation | We leverage the physical variable stiffness characteristics of compressed air. As a result, the air spring completely absorbs fine bumps and mechanical resonance during high-speed driving. Moreover, this greatly reduces driver fatigue and protects cargo safety. |
| Industrial Anti-Aging & Extreme Weather Resistance | We add specialty anti-ozone and anti-UV agents to the outer rubber compound. Consequently, it perfectly resists -40°C extreme cold, intense sunlight, and road de-icing salt chemical attack. |
Applicable Car Brands & Models
The OE 6122 N part number guarantees that the air spring matches the exact original equipment dimensions, load capacity, pressure ratings, and mounting configurations specified by the manufacturer, ensuring a direct, hassle-free installation.
Common warning symptoms include:
Chassis Sagging: The vehicle or trailer drops on one corner or axle after parking, indicating a pneumatic leak.
Harsh, Bouncing Ride: The suspension loses its damping elasticity, causing uncontrolled bouncing over road bumps.
Visible Rubber Cracking: Deep surface cracks, ozone checking, or cord exposure visible on the flexible rubber bellows.
Yes. We offer competitive wholesale pricing and secure industrial packaging for commercial fleet operators, distributors, and truck repair shops purchasing in volume.
Each unit is treated with protective powder, sealed in a heavy-duty moisture-proof poly bag, and packed inside a reinforced industrial corrugated box to prevent physical deformation or rubber degradation during global transit.
