Industrial Air Springs & Bespoke Pneumatic Suspension
Designed and Supplied in the UK
UK Specialists in Industrial Air Suspension
On Air Suspension are a UK supplier of industrial air springs, rubber bellows and pneumatic actuators, with the in-house engineering capability to design and produce bespoke solutions for applications across manufacturing, agriculture, mining, construction, offshore and beyond.
​
Unlike standard distributors, we don't just supply from a catalogue. We employ design engineers who can develop custom air springs from scratch, produce like-for-like replacements for discontinued components, and engineer solutions for applications where off-the-shelf products fall short. With large UK stock holdings and strong influence over our manufacturing partners' production schedules, we also offer availability and lead times that standard supply channels rarely match.
​
If you're searching for industrial air springs in the UK — whether for a known application, an urgent replacement, or a bespoke requirement — we're the right people to speak to.
What We Offer
In-House Design Engineers
We employ design engineers with the capability to develop air spring solutions from scratch or adapt existing designs to meet new requirements. This is not a capability you'll find at most UK suppliers — it means we can take on projects that others have to turn away, and deliver components that simply aren't available off the shelf.
Like-for-Like Replacement
If you have an existing air spring that is discontinued, difficult to source, or no longer supported by the original manufacturer, we can produce a direct replacement to the original specification. This is something we have successfully delivered for clients who had exhausted all other options — send us your existing component, drawings, or even just the original part number, and our design engineers will engineer a match.
Availability & Lead Times
​We carry substantial stock across a wide range of air spring types and specifications, and our strong relationships with manufacturing partners give us genuine influence over production scheduling. For urgent or high-volume requirements, this means we can move faster than standard distribution lead times — often significantly so.
Applications
Our pneumatic solutions are suited to a broad range of industrial environments, including:

Air Spring Types We Supply
Single, double and triple convoluted air springs — the standard forms of industrial air spring, used for suspension, actuation and vibration isolation. Available across a wide range of diameters and load capacities, in dismountable, crimped and bead-ring assembly configurations.
​
Sleeve air springs — for applications requiring longer stroke or a smaller installed diameter.
​
Air springs as actuators — unlike conventional rod-type pneumatic cylinders, a bellows actuator generates force by inflating a rubber bellow. No piston rod, no internal seals, no lubrication, and inherent tolerance of lateral and angular misalignment — well suited to pressing, lifting, clamping and tensioning duties where a conventional cylinder would wear or bind.
​
Air springs as vibration isolators — the low natural frequency of an air spring makes it an effective replacement for coil springs and rubber-metal mounts, isolating the large majority of unwanted vibration from industrial machinery and protecting both equipment and workplace.
​
Material options — beyond standard rubber compounds, bellows can be specified in butyl (ozone and UV endurance), nitrile (oil and fuel resistance), EPDM (high temperature) and chloroprene (seawater resistance), with stainless steel end closures (AISI 304/316) where corrosion resistance is required.
​
Springs can be specified by dimensions, load and stroke requirements — or by cross-reference to an existing part number from any major manufacturer.

Manufacturing Partner
For industrial applications, we work with Manufacturas Oria — a specialist air spring manufacturer with over 50 years in the industry. Their range spans standard single, double and triple convoluted bellows through to fully bespoke designs, in dismountable, crimped and bead-ring configurations, with bellow diameters from 120mm to 950mm and load capacities up to 450 kN.
This relationship gives us access to genuine engineering depth alongside the responsiveness of a smaller specialist manufacturer — able to take on demanding one-off and low-volume work that larger suppliers are slower to prioritise.
How a Bespoke Project Works
-
Requirement — send drawings, a sample component, a part number, or just the application parameters (load, stroke, envelope, operating environment)
-
Design — our engineers develop the specification on CAD, prototyping with 3D printing where geometry needs validating
-
Manufacture — production through our manufacturing partners, to our specification
-
Validation — production runs through our manufacturing partners' factory testing regimes, including pressure testing of produced components to confirm they meet specification. And if a fitted spring is ever suspected of leaking or underperforming in service, we can pressure-test it on our own test rig to confirm the fault before replacement.
Frequently Asked Questions
Can you replace a discontinued industrial air spring? Yes. If the original manufacturer no longer supports your component, our design engineers can produce a like-for-like replacement to the original specification. Send us the existing component, drawings, or just the part number stamped on the unit, and we'll engineer a match.
​
How do I identify my air spring? Check the bellow for moulded markings or a stamped part number first — most manufacturers mark the rubber. If no marking is legible, measure the maximum outside diameter, the installed and maximum heights, count the convolutions, and note the mounting arrangement (studs, threaded holes, bead rings). Photographs alongside those measurements are usually enough for us to identify a match.
​
What information do you need for a bespoke quote? The application, load requirements, required stroke, the installation envelope (available space), and the operating environment — temperature range, and any exposure to oils, chemicals or seawater. Existing component details or drawings help but aren't essential.
​
Do you supply equivalents for other manufacturers' air springs? Yes. Springs can be cross-referenced against part numbers from all major air spring manufacturers. Some references relate to the bellows component only, so mounting configurations should always be confirmed before ordering — we can help with this.
​
What are typical lead times? Stocked items despatch quickly. Bespoke and low-volume manufactured items depend on specification — but our production relationships mean lead times are often significantly shorter than standard distribution channels. Contact us with your requirement for a realistic timeframe.
