Firestone W01-M58-6140 Two Ply Air Spring for Airmount Isolation with 1/4 BSP

AIRSUSTECH 1B130070 is a replacement air spring developed for applications using the Firestone W01-M58-6140, Style 16 two-ply bellows assembly. It features a compact two-ply reinforced bellows, a ZG1/4'' air inlet, approximately 114 mm diameter, and 44 mm mounting spacing, making it suitable for applications where space-efficient pneumatic support is required.

The Firestone Style 16 configuration is designed for pneumatic actuation and vibration isolation. By adjusting the internal air pressure, the air spring can provide controllable pneumatic force for lifting, pressing, or positioning, while its flexible rubber bellows helps absorb vibration and mechanical shock. Firestone's published data specifies a recommended Airmount design height of 75 mm for W01-M58-6140, which should also be considered when checking replacement compatibility.

For replacement, buyers should verify the air inlet, mounting spacing, diameter, design height, and available installation clearance before ordering.

The OEM part number is an important starting point, but physical compatibility should also be verified before replacement. Check the 114 mm cover plate diameter, 44 mm mounting center distance, M8 × 1.25 mounting thread, and 1/4 BSP air inlet against the existing unit. The available installation height and required operating range should also be confirmed to ensure the air spring fits correctly and performs as expected.

These dimensions are not just technical specifications. They determine whether the replacement can mount correctly, connect to the existing pneumatic system, and operate within the available space. For buyers sourcing AIRSUSTECH 1B130070 as a replacement for Firestone W01-M58-6140, checking these points before ordering can help avoid installation problems and unnecessary modifications.
