Airtac ACED Double-acting Compact Cylinder ACED125X300S
The AirTAC Airtac ACED Double-acting Compact Cylinder ACED125X300S is a genuine double acting, double rod ISO 21287 compact air cylinder with a Ø125mm bore and 300mm 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.

About the Airtac ACED Double-acting Compact Cylinder ACED125X300S
The ACED125X300S is a double acting, double-rod compact cylinder built to ISO 21287: a 25 mm hard-chrome-plated S45C rod exits BOTH covers, so the 125 mm bore delivers an identical 5890.5 N at 0.5 MPa (8246.7 N at 0.7 MPa) on every stroke because both sides work on the rod-side area. The through-rod resists rotation and side load, gives a symmetric mounting face, and the rear rod can carry a sensor flag or a second tool. Air supply is 0.15-1.0 MPa (22-145 psi), speed 30-500 mm/s, and a fixed TPU bumper decelerates the piston at each end.
The hard-anodized aluminium body with roller-burnished bore saves about 50% of the mounting length of an ISO 15552 profile cylinder, so this heavy 125 mm force class still fits tight presses, gantries and guarding. The -S code on this model means the magnet is fitted: CMSE / DMSE reed or solid-state switches mount directly in the body slots for end-of-stroke signalling. As a planning figure, treat roughly 0.6 of the rating - about 3534 N (roughly 360 kg) - as the usable work force at 0.5 MPa, which corresponds to lifting about 300 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.
Theoretical Output Force (Ø125mm)
| 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).

Where the Airtac ACED Double-acting Compact Cylinder ACED125X300S Is Used
Heavy stamping and forming fixtures
The equal 5890.5 N push and pull at 0.5 MPa suits a 300 mm-stroke punch or forming tool that must retract under the same force it presses with, inside a compact press head.
Pallet stacker lift columns
With about 300 kg of vertical lift capacity at a 2:1 margin, the through-rod guides a lift table or pallet clamp symmetrically without an external guide post.
Foundry gate and ladle positioning
The rear rod carries a position flag for DMSE switches while the front rod drives a refractory gate, and the short ISO 21287 body slots into crowded furnace-side frames.
Is the Airtac ACED Double-acting Compact Cylinder ACED125X300S the Right Cylinder?
At 5890.5 N per direction this is the top of the ACED range; step down to the ACED100 bore (3769.9 N at 0.5 MPa) for lighter clamps or up from the 80 mm bore (2356.2 N) if 125 mm is oversized. The 300 mm stroke sits exactly at the bore's maximum standard length, so no made-to-order stroke is needed. Remember that a plain double-rod cylinder drifts when air is lost - add a rod lock or pilot check valve if the load must stay put. FA/FB flanges, LB feet and FTC brackets bolt to the ISO 21287 face, and I/Y rod knuckles suit the 25 mm female M16x2.0 thread.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Short stroke fits the compact body
- ✓ Port/thread type (PT / G)
- ✓ Add -S if you need the magnet for sensors
- ✓ Rod type (female / male B) & mount (FA/LB/CA)
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Compact body: keep the stroke short and avoid side load on the rod.
- check Do not dismantle the threaded front/back covers.
- check Keep speed within the rated range; the TPU bumper absorbs stroke-end energy.
- check Installation by qualified personnel per AirTAC docs.
Airtac ACED Double-acting Compact Cylinder ACED125X300S FAQ
Because a rod exits both covers, force is equal in both directions: 5890.5 N at 0.5 MPa and 8246.7 N at 0.7 MPa on every stroke, peaking at about 1201.3 kgf at 1.0 MPa. Working pressure is 0.15-1.0 MPa (22-145 psi) with 1.5 MPa (215 psi) proof pressure, speed 30-500 mm/s, and the 25 mm rod ends in a female M16x2.0 thread with a 1/4" PT port.
The ISO 21287 short body cuts mounting length by about 50% versus an ISO 15552 profile cylinder, so a 125 mm bore with a 300 mm stroke still fits constrained machine frames. This ACED125X300S carries the optional -S magnet, so CMSE / DMSE reed or solid-state switches clip into the body slots for stroke-end detection; fixed TPU bumpers absorb end-of-stroke energy at both covers.
