The AirTAC Airtac ACED Double-acting Compact Cylinder ACED125X120 is a genuine double acting, double rod ISO 21287 compact air cylinder with a Ø125mm bore and 120mm stroke, 1/4" air ports and a hard-anodized aluminium body. Its short compact envelope saves about 50% of the mounting length of an ISO 15552 profile cylinder.
A double acting ISO 21287 compact cylinder with a rod leaving BOTH covers, the ACED125X120 pushes with the same 5890.5 N at 0.5 MPa in either direction because both strokes work on the rod-side area. At 0.7 MPa that rises to 8246.7 N, and the bore tops out near 1201 kgf at 1.0 MPa. The through-rod resists rotation and side load, and the rear rod can carry a sensor flag or a second tool.
The hard-anodized aluminium body with an S45C hard-chrome-plated rod runs on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi), 30-500 mm/s, from -20 to +70 C. Its short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so a 125 mm bore fits presses and gantries that cannot house a full-length body. As a rule of thumb, plan on roughly 3534 N of usable work at 0.5 MPa, which lifts about 180 kg vertically with a 2:1 margin.

Specifications follow the official AirTAC ACE-series (ISO 21287) datasheet. Body: hard-anodized aluminium alloy; piston rod: S45C carbon steel with hard-chrome plating. Rod type: female thread (blank) or male thread (B). Thread options: PT (blank) / G. A built-in magnet is OPTIONAL — add the -S code to fit CMSE / DMSE position sensors.
| Pressure | Force (both ways) |
|---|---|
| 0.5 MPa | 5890 N |
| 0.7 MPa | 8247 N |
| Max (@1.0 MPa) | 1201 kgf |
Double-rod: a rod exits both covers, so output force is equal in both directions (rod-side area used).
| ACED | ISO 21287 compact cylinder (double-rod). |
|---|---|
| 125 | Bore size in mm. |
| ×120 | Stroke length in mm. |
| S | Optional built-in magnet for CMSE / DMSE sensors (omit for no magnet). |
| B | Rod type: B = male thread; blank = female thread. |
ACE-family variants: ACE (double acting), ASE / ATE (single acting push / pull), ACED (double rod), ACEJ (adjustable stroke), TACE / TACED (non-rotating twin-guide yoke). Mounting accessories: FA / FB flange, LB foot, CA / CB clevis, CR, SDB pivot, FTC; plus I and Y knuckles. Thread PT (blank) / G.
The 5890.5 N through-rod at 0.5 MPa compresses light scrap in a recycling baler, and the symmetric rod keeps the platen square under off-center loads.
A 120 mm stroke presses plywood packs on a pallet line; the short ISO 21287 body slots into the press frame where a full-length profile cylinder will not fit.
With about 180 kg of vertical capacity at a 2:1 margin, the double rod guides a pick-up arm for engine castings without a separate guide post.
For heavy clamping or lifting, compare the 100 mm bore (3769.9 N at 0.5 MPa) if your load is lighter, or step to this 125 mm bore when you need the full 5890.5 N. Stroke 120 mm sits well inside the 300 mm maximum standard stroke for this bore. If the load must stay put when air is lost, add a rod lock or pilot check - the bumper only decelerates at the ends and never holds position. Female M16x2.0 rod thread, PT ports, FA/FB flange, LB foot and FTC brackets, plus I/Y rod knuckles, bolt to the ISO 21287 face. Order the -S code if you want the optional magnet for CMSE / DMSE switches; without -S no magnet is fitted.
Quick checklist
Yes - the rod-side area is identical on both strokes, so output is 5890.5 N at 0.5 MPa and 8246.7 N at 0.7 MPa in EITHER direction. Maximum output at 1.0 MPa is about 1201 kgf. Operating range is 0.15-1.0 MPa (22-145 psi), proof 1.5 MPa (215 psi), speed 30-500 mm/s, with a fixed TPU bumper at both ends.
This code ships with a female M16x2.0 rod thread, 1/4" PT ports, a hard-anodized aluminium body and S45C hard-chrome rod, and no magnet. Sensing requires the optional -S magnet code, which lets CMSE or DMSE switches read position on the body slots. For mounting, FA/FB flanges, LB feet and FTC brackets plus I/Y knuckles fit the standard ISO 21287 face; outline dimensions - confirm from datasheet.
