The AirTAC Airtac ACED Double-acting Compact Cylinder ACED125X35S is a genuine double acting, double rod ISO 21287 compact air cylinder with a Ø125mm bore and 35mm 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 through-rod: the ACED125X35S pushes a 25 mm rod out of BOTH covers, so thrust is identical on each stroke - 5890.5 N at 0.5 MPa and 8246.7 N at 0.7 MPa, equal in both directions because both sides work on the rod-side area. The 125 mm bore tops the ACED range at 1201.3 kgf maximum, and the short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so this force class fits presses and gantries that cannot accept a full-length body.
The hard-anodized aluminium body carries a hard-chrome plated S45C rod, with a fixed TPU bumper at each end to soften end-of-stroke impact. Because the -S magnet is fitted, CMSE or DMSE reed or solid-state switches can be clamped directly into the body slots for end-position feedback. As a working rule, plan on roughly 3534 N of usable push at 0.5 MPa (about 60% of rating), and for vertical work the rod lifts around 300 kg with a 2:1 margin. Speed range is 30-500 mm/s on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi).

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.

| 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).

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 symmetric through-rod clamps a casting from both sides of a 4th-axis fixture with one cylinder, delivering 5890.5 N per jaw at 0.5 MPa inside a body short enough for the fixture plate.
With about 300 kg of vertical lift capacity at a 2:1 margin, the double rod guides a die-cart elevator platen without a separate guide column, and the second rod end carries a position flag.
A short 35 mm stroke ejects filled cartons off a conveyor stop at up to 8246.7 N at 0.7 MPa, with the fitted magnet and a DMSE switch confirming home position each cycle.
At 5890.5 N per direction at 0.5 MPa, the 125 mm bore sits two steps above the 100 mm bore (3769.9 N) and well above the 80 mm bore (2356.2 N) - choose 125 mm when a heavy clamp or lift needs the extra margin in a short envelope. The 35 mm stroke is well inside the 300 mm maximum standard stroke for this bore, so it ships as a standard build. Note that with air removed the piston drifts freely; if the load must stay put on pressure loss, add a rod lock or pilot check valve. Mounting brackets (FA/FB flange, LB foot, FTC) and I/Y rod knuckles bolt straight to the ISO 21287 face, and the female M16x2.0 rod thread on both ends accepts standard rod accessories.
Quick checklist
Yes - it is a double-rod cylinder, so a 25 mm rod exits both covers and every stroke uses the rod-side area. Output is 5890.5 N at 0.5 MPa and 8246.7 N at 0.7 MPa, identical push and pull, with a maximum of 1201.3 kgf at 1.0 MPa. Operating pressure is 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), speed 30-500 mm/s, and the 1/4" port size follows the 125 mm bore.
The compact body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so a 125 mm force class fits where a full-length body will not, and FA/FB flange, LB foot and FTC brackets bolt to the standard ISO 21287 face. This ACED125X35S carries the optional -S magnet, so CMSE or DMSE switches mount in the body slots for end-of-stroke detection. A fixed TPU bumper at each end absorbs end-of-stroke shock, and the female M16x2.0 thread on both rod ends accepts standard knuckles.
