New DAF-approved aftermarket air bellows
TRP Parts Ireland now supplies air bellows with OE-level quality and durability for most older DAF models. Competitively priced, they are said to be the only aftermarket types that are tested and validated by DAF Product Development.
Heavy loads bouncing along uneven roads cause huge stresses in commercial truck axles. New trucks have specially designed air bellows that help minimise shocks and vibration. They make for a safer, more comfortable ride for drivers, and protect expensive onboard equipment and delicate loads from damage.
Air bellows ensure smooth raising and lowering of lift axles, and reduce tyre wear when the vehicle is empty.
Regular inspection is needed to check whether air bellows should be replaced to prevent suspension failure. Warning signs include:
• visible damage like cracks, tears, cuts or significant wear to the rubber surface,
• air leaks, usually causing a hissing sound,
• truck sitting lower on one side with suspension looking or feeling uneven,
• increased vibration or bounce during driving.
Backed by a two-year warranty, TRP says its Air Bellows are engineered for durability and performance in demanding environments.
They feature a reinforced elastomer construction with carefully selected fillers and fabrics, ensuring consistent quality through on-site mixing and precision calendaring.
The vulcanization process enhances elasticity and long-term reliability, while custom-designed crimping plates simplify installation.
