   "nb-parts rows: model name, the Ø pair as printed (the text does not label which Ø is the rod), the thread as printed and the stroke range in mm.

Extended-length formulas that appeared in a machine reading of the catalogue are not shown because the source text does not state them.",
   "SUSPA type 16-3: rod Ø8 mm, tube Ø21.5 mm, tube end M8 x 1.0, rod end M6 x 1.0, tube length 85 to 535 mm, force range 100 to 600 N (the page prints the minimum tube length as 'rod (B) + 37'), all as printed. The page does not give the stroke / extended-length pairs, so none is shown.",
   "McMaster-Carr rows are inches as printed on its gas spring page: the painted-steel series with eyelet fittings (extended, compressed and stroke; body Ø0.47 in, rod Ø0.16 in, M4 rod thread) and the 316 stainless adjustable-force series (M8 rod on a 0.88 in body, M10 rod on a 1.17 in body, with extended and compressed force in lbf). The page states that each end fitting adds its own Length 1 to the extended and compressed lengths of the spring, so the figures are for the spring without fittings.",
   "End fittings, eyelets and ball sockets and their threads are on gas-spring-end-fittings. The gas-spring-cylinder-18mm page is a different thing (a thermodynamic gas spring in a free-piston Stirling engine); springs covers coil springs.",
   "No file: the gas spring is a cylinder and rod whose end fittings and tube ends are not given as numbers. McMaster-Carr sells gas springs, locking gas springs and end fittings with per-part STEP; linked, not copied."

The catalogue's GF 20/40 appears twice with different data (M14, 50–600 mm; M14x1.5, 100–700 mm); both are shown. Extended-length formulas that appeared in a machine reading of the catalogue are not shown because the source text does not state them.\n- SUSPA type 16-3: rod Ø8 mm, tube Ø21.5 mm, tube end M8 x 1.0, rod end M6 x 1.0, tube length 85 to 535 mm, force range 100 to 600 N (the page prints the minimum tube length as 'rod (B) + 37'), all as printed. The page does not give the stroke / extended-length pairs, so none is shown.\n- McMaster-Carr rows are inches as printed on its gas spring page: the painted-steel series with eyelet fittings (extended, compressed and stroke; body Ø0.47 in, rod Ø0.16 in, M4 rod thread) and the 316 stainless adjustable-force series (M8 rod on a 0.88 in body, M10 rod on a 1.17 in body, with extended and compressed force in lbf). The page states that each end fitting adds its own Length 1 to the extended and compressed lengths of the spring, so the figures are for the spring without fittings.\n- End fittings, eyelets and ball sockets and their threads are on gas-spring-end-fittings. The gas-spring-cylinder-18mm page is a different thing (a thermodynamic gas spring in a free-piston Stirling engine); springs covers coil springs.\n- No file: the gas spring is a cylinder and rod whose end fittings and tube ends are not given as numbers. McMaster-Carr sells gas springs, locking gas springs and end fittings with per-part STEP; linked, not copied.\n\nsource  model / part  diameters  end thread  stroke  extended length  compressed length  force\nnb-parts  GF 3/10  Ø 3 / 10 mm  M3.5 / M4 (as printed)  10–80 mm  —  —  —\nnb-parts  GF 6/15 M5  Ø 6 / 15 mm  M5  50–200 mm  —  —  —\nnb-parts  GF 8/19 M6  Ø 8 / 19 mm  M6  75–300 mm  —  —  —\nnb-parts  GF 10/22 M8  Ø 10 / 22 mm  M8  75–400 mm  —  —  —\nnb-parts  GF 10/28 M8  Ø 10 / 28 mm  M8  75–400 mm  —  —  —\nnb-parts  GF 14/28 M10  Ø 14 / 28 mm  M10  100–500 mm  —  —  —\nnb-parts  GF 20/40 M14  Ø 20 / 40 mm  M14  50–600 mm  —  —  —\nnb-parts  GF 20/40 (standard section)  Ø 20 / 40 mm  M14x1.5  100–700 mm  —  —  —\nnb-parts  GF 25/55  Ø 25 / 55 mm  M20x1.5  100–700 mm  —  —  —\nnb-parts  GF 30/65  Ø 30 / 65 mm  M24x2  100–700 mm  —  —  —\nnb-parts  GF 10/22 with welded eyelets  Ø 10 / 22 mm  — (eyelets)  250–1150 mm  —  —  —\nSUSPA type 16-3  16-3  rod Ø8 / tube Ø21.5 mm  tube end M8 x 1.0;
