1RC-150-1C Wuhlermann Air Spring Equivalent to Firestone W01-M58-6155 Max. O.D. 165MM

Product Introduction and Specifications

AIRSUSTECH 1B7070 is a replacement option for WUHLERMANN No. 1RC-150-1C. It belongs to a compact single-convoluted air spring configuration commonly used for pneumatic support, vibration isolation and controlled movement in industrial equipment.

Installation Space and Working Height

The 1B7070 has a 150 mm natural diameter and a maximum outside diameter of 165 mm. Its 50–115 mm working-height range should be considered together with the required stroke and surrounding clearance when replacing an existing 1RC-150-1C.

The available installation space is not determined by the nominal diameter alone. Clearance around the bellows should also be checked at the maximum operating diameter and throughout the working stroke. This helps prevent contact with nearby components and ensures that the air spring can move freely within the intended operating range.

OEM Cross Reference

Why Can One Air Spring Have So Many Part Numbers?

Different manufacturers may assign their own part numbers to air springs with similar dimensions, mounting configurations, and functional characteristics. As a result, one air spring may have several cross-reference or replacement numbers across different brands.

However, similar part numbers do not automatically mean the products are directly interchangeable. Before selecting a replacement air spring, the mounting pattern, air connection, working height, outside diameter, and available installation space should be checked against the existing unit.

For this reason, part numbers are a useful starting point for identifying an air spring, but dimensional and application checks are essential when confirming replacement compatibility.
