The AirTAC Airtac ACED Double-acting Compact Cylinder ACED125X70 is a genuine double acting, double rod ISO 21287 compact air cylinder with a Ø125mm bore and 70mm 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 compact cylinder built to ISO 21287, the ACED125X70 pushes a 25 mm rod out of BOTH covers, so the 125 mm bore delivers the same 5890.5 N at 0.5 MPa (8246.7 N at 0.7 MPa) on every stroke - no push-versus-pull mismatch to design around. The short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, which is why it fits heavy presses and clamping gantries where a full-length body simply will not go.
The hard-anodized aluminium body carries a roller-burnished bore, the S45C rod is hard-chrome plated, and a fixed TPU bumper at each end absorbs end-of-stroke shock. Run it on 0.15-1.0 MPa (22-145 psi) at 30-500 mm/s. As a working figure, keep real work to roughly 3534 N at 0.5 MPa, which is about 360 kg of vertical lift with margin - enough to raise a full pallet of castings or close a heavy die cart gate. The through-rod also resists rotation and side load, and the rear rod can carry a fixture or sensor flag.

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. |
| ×70 | 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.
5890.5 N at 0.5 MPa clamps thick sheet-metal dies symmetrically from both rod ends, and the 70 mm stroke suits quick-change die shoes.
With about 300 kg of vertical lift capacity at a 2:1 margin, the through-rod raises pallet stops or gate arms with equal force up and down.
The 125 mm bore drives mould carriers at 30-500 mm/s while the rear rod carries a position flag, all inside a body about 50% shorter than an ISO 15552 profile cylinder.
At 5890.5 N per stroke this is the top of the ACED range; if your load is lighter, the ACED100X70 gives 3769.9 N at 0.5 MPa and the ACED80X70 gives 2356.2 N - step up only when the mass or cycle force demands it. Stroke 70 mm sits well inside the 300 mm max standard for bore 125, so no made-to-order build is needed. Female M16x2.0 rod thread and 1/4" PT ports come as coded. Remember that a plain double-rod cylinder drifts when air is lost - add a rod lock or pilot check if the load must stay put. Mounting brackets (FA/FB flange, LB foot, FTC) plus I/Y rod knuckles bolt to the ISO 21287 face, and the optional -S magnet enables CMSE / DMSE switches; without -S there is no magnet.
Quick checklist
Yes - it is a double-rod cylinder, so a rod exits both covers and both strokes use the rod-side area. Output is 5890.5 N at 0.5 MPa and 8246.7 N at 0.7 MPa in EITHER direction, with a maximum of 1201.3 kgf at 1.0 MPa. Operating range is 0.15-1.0 MPa (22-145 psi), proof 1.5 MPa (215 psi), speed 30-500 mm/s, air filtered to 40 um.
The body is hard-anodized aluminium with a roller-burnished bore, the 25 mm rod is S45C with hard-chrome plating, and a fixed TPU bumper at each end absorbs end-of-stroke energy - it does not lock or hold a load. FA/FB flange, LB foot and FTC brackets plus I/Y rod knuckles mount on the standard ISO 21287 face. Position switches (CMSE / DMSE) work only when you order the optional -S magnet; this model code has no magnet fitted.
