4½ x 1 Pneumatic Rubber Air Bag Design H. 78MM W01R584050 Firestone Air Spring

The 4½ x 1 pneumatic rubber air bag (design height 78 mm, model W01R584050) is a single-convolution industrial air spring engineered as a direct replacement for Firestone W01-R58-4050 and equivalent Continental ContiTech, Dunlop, Norgren, and Parker bellows. Built to OEM standard with a one-year warranty, it delivers reliable load isolation and vibration damping across a working pressure range of 0–8 bar.

AIRSUSTECH air bellows feature a flexible, corrugated rubber body made from inner and outer rubber layers, reinforced fabric plies, and steel bead rings bonded together through vulcanization. Available in single, double, and triple convoluted designs, the bellows may also incorporate central rings between convolutions, depending on the design.

The complete air spring is assembled by fitting metal end closures to the bellows. Depending on the mounting requirements, three design options are available.

• Dismountable Design — This design consists of two clamping bead rings and top and bottom plates, allowing the assembly to be disassembled when required. The top plate includes an air inlet connection, while mounting studs or threaded holes are provided for installation.
• Crimped Design — In this non-dismountable design, the top and bottom bead plates are mechanically crimped to the bellows assembly. The plates feature blind nuts for mounting, and the top plate includes an air inlet connection.
• Bead Ring Design — This dismountable design uses bead rings with socket-head, threaded, or countersunk configurations. Top and bottom plates are not included in the standard supply. The air spring can be mounted directly to compatible machine components or installed using plates supplied by the customer.
