If you are preparing to order replacements gas springs or if you have an emergency and you are unable to get them from your current supplier, you may have questions. How do you ensure you are getting the right gas springs, especially if replacing another brand like Dadco, Kaller, or Hyson? Many MROs and purchasing managers worry about ensuring they have the right parts and are understandably wary at the prospect of changing brands.
We are frequently asked about the part identification system for gas springs and how to convert an existing product to anther brand.
Part Identification for Gas Springs
Gas springs are identified alphanumerically. The letters represent the product series from the manufacturer. The first set of numbers represent the initial contact force in decanewtons (daN), and the second set of numbers represent the useable stroke length.
For example, RV170-025: The gas springs initial contact force is 170 daN (382 lbs) and useable stroke is 25mm.
Part Identification is Global
Another important factor in replacing gas springs is understanding how the part identification system works. Gas spring part identification is the same for all manufacturers, and adheres to the ISO and VDI standards to establish consistency in the industry. These standards state that springs must be labeled based on their force in decanewtons (daN) and stroke length.
For example, RV170-025 is directly interchangeable with X 170-025, T3-170 x 025, and U.0175.025. These parts are very similarly labeled, as they follow the ISO and VDI gas spring identification standards.
