Torpress Spare Parts for Air Suspension Systems

In this section of our online catalogue, we offer a wide range of Torpress air springs and pneumatic bellows specifically designed for the suspension systems of heavy-duty vehicles. These components act as the main elastic element, replacing or complementing traditional leaf springs to effectively absorb road irregularities.

Our selection is aimed at maintenance professionals and transport fleets seeking reliable spare parts for trucks, trailers, and buses. Proper maintenance of these air springs is essential to ensure chassis leveling, protect cargo during transport, and guarantee stable and safe driving conditions.

How to select the correct air spring

• OEM reference: The most accurate way to ensure compatibility is by matching the original manufacturer’s part number of the component being replaced.
• Dimensions and stroke: Verify maximum and minimum height, as well as diameter, to ensure proper fit within the wheel arch without interference.
• Mounting system: Check the layout and thread size of studs, nuts, and air inlets on both the upper and lower plates.
• Piston type: Determine whether your vehicle requires a complete assembly with piston (metal or plastic) or only the rubber bellows.
• Axle position: Ensure the spare part is suitable for the specific location, whether on the drive axle, steering axle, or trailer axle.

Frequently Asked Questions

What is a Torpress and what is its function in an industrial vehicle?

Torpress is a pneumatic bellows-type air spring that forms part of the air suspension system. Its function is to support the vehicle’s weight using compressed air, allowing chassis height regulation and absorbing vibrations to improve ride comfort and load stability.

What are the symptoms of a faulty Torpress?

The most common signs include loss of vehicle height after being parked (air leaks), visible cracks in the rubber bellows, or unstable and excessively rigid driving behavior. Periodic visual inspections are recommended to detect premature wear.

Are these spare parts compatible with all truck brands?

There is no universal model. Each Torpress unit is designed for specific vehicle makes and models. You must consult the technical specifications and cross-reference numbers of each product to confirm compatibility with your truck or trailer.

Can a punctured air bellows be repaired?

As a general rule, repairing a damaged air bellows with patches is not recommended, as these components operate under high pressure and constant flexing. The professional and safe solution to restore suspension functionality is complete replacement of the affected component.
