Compact, cost-efficient and configured to your exact specifications
Modular Air Spring
Space. Comfort. Cost. All simplified.
In rail bogie design, where space is at a premium, cost is a critical concern, and passenger comfort is a priority, you now have a solution that can be configured to your precise specifications—quickly, easily, and without the need for complex molding and tooling.
Introducing our new Modular Air Spring
- Compact, space-saving dimensions maximize available space
- Modular configuration means the air spring is fully adjustable to your requirements
- ‘Clip-to-fit’ design keeps lifecycle costs to a minimum
- Robust, lightweight and highly flexible

One product. A suite of solutions.
Modular Air Spring offers increased performance with cost-saving benefits, all whilst fitting seamlessly with your existing interfaces.
Compact, space-saving dimensions
Space is at a premium in rail transport, from light carriages to double-decker trains. The compact design of the Modular Air Spring maximizes available space, allowing for more passengers and cargo.
Cost-efficiency
Because the Modular Air Spring clips together, rather than needing screws or bolts, rubber can be replaced and metal reused, significantly reducing lifecycle costs and supporting your sustainability goals.
Modular configuration
The Modular Air Spring’s unique design means there’s no need for expensive molding or tooling. It can be adapted to fit your existing interfaces on bogies and cars.
Ideal for orders of all sizes
Because there’s no new molding to be done, the Modular Air Spring is ideal for any size of order – even if that’s 500 or fewer.
Configure it your way.
With a range of interface options available, every element of the Modular AirSpring can be customized to fit seamlessly with your current system, deliveringrobust performance, simple and sustainable maintenance options and a lower TCO.
Interface Adapters + Support Plate
Every Air Spring system features a single-size support plate with a universal interface designed to fit standardized bogie and vehicle designs. For unique interfaces, easy connection is enabled with interface adapters.
Sliding Plate
Innovative sliding-plate technology reduces the need for additional fixation parts, whilst the easy-to-swap design means the rim plate can be retained rather than scrapped. This streamlined system enables easier maintenance, increased sustainability and offers a lower total cost of ownership (TCO).
Bellows
All Air Spring systems come equipped with robust, belted bellows. The compact design maximizes vertical load capacity, increasing available space for passengers or freight.
Each system combines two exchangeable bellows with two variants of auxiliary spring, meeting a wide range of lateral stiffness values.
Rim Plate
Each Air Spring system has a standard and weight-optimized rim plate: the standard plate is optimized for both cost and height, whilst the weight-optimized plate is designed to be compatible with additional system height.
Hard Stop
Every Air Spring features a single hard stop with a simple and smart design. At no additional cost, the required length can be adjusted via an intuitive turning process.The hard stop comes included as standard but can be omitted if not needed.
Auxiliary Spring
Offering at least two stiffness variants, the auxiliary spring enables easy integration of a hard stop whilst improving system stability, especially at higher loads.
The unique interface with the rim plate reduces wear meaning improved life-cycle costs.
Special docking points on the underside of the spring allow the option to use a standard pin interface or a customized bottom plate.
Bottom Plate
For bogie frames incompatible with the auxiliary spring’s universal pin interface, easy connection can be achieved via a customized bottom plate.
If the spring is replaced, the bottom plate can be reused meaning a more sustainable system with a lower TCO.
