Product Description
14 ½ × 3 Triple Type Air Spring Dunlop AIRSUSTECH 3B14.5X3T for Norgren M/31143
AIRSUSTECH 3B14.5X3T is a triple convoluted industrial air spring designed as a replacement option for Norgren M/31143 and related 14 1/2 × 3 air spring references. Its reinforced rubber bellows provides controlled pneumatic movement, load support, and effective vibration isolation, making it suitable for demanding industrial equipment.
The 14 1/2 × 3 configuration is also cross-referenced with well-known air spring references including Firestone W01-R58-4065 and ContiTech FT 614-36 DS. This broad OEM compatibility makes 3B14.5X3T a practical sourcing option for distributors, maintenance companies, and equipment manufacturers looking for a reliable replacement air spring.
Using compressed air as the working medium, AIRSUSTECH 3B14.5X3T can provide pneumatic actuation, vibration isolation, shock absorption, and adjustable load support. Its triple-convoluted construction is particularly useful where a longer stroke and flexible height adjustment are required.

Compatibility Check with Norgren M/31143
Before replacing an existing Norgren M/31143 air spring, buyers should compare the key installation and operating dimensions rather than relying on the model number alone. For AIRSUSTECH 3B14.5X3T, the main points to check are:
- Plate Diameter: The cover plate diameter is 310 mm, which should be compared with the original M/31143 mounting plate.
- Mounting Center Distance: The mounting-hole center distance is 282.5 mm. This dimension determines whether the replacement can align correctly with the existing equipment.
- Mounting Bolts: The mounting configuration is 4 × M10, so both the thread size and hole arrangement should be confirmed before ordering.
- Air Port: The standard air connection is G1/2. Make sure the existing pneumatic line and fitting are compatible with this connection.
- Working Height and Stroke: The required working height and available stroke should be checked according to the actual machine operating position. Sufficient clearance is also necessary to prevent the bellows from contacting surrounding components during compression and extension.
