Airtac ACED Double-acting Compact Cylinder ACED125X300B
The AirTAC Airtac ACED Double-acting Compact Cylinder ACED125X300B 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 ACED125X300B
A double acting compact cylinder built to ISO 21287, the ACED125X300B pushes a 25 mm rod out of BOTH covers, so thrust is identical on the extend and retract strokes: 5890.5 N at 0.5 MPa and 8246.7 N at 0.7 MPa. Because the body is a short ISO 21287 design, it takes up roughly half the mounting length of an ISO 15552 profile cylinder, which matters when a 300 mm stroke must fit inside a press frame or machine guard.
The through-rod resists rotation and side load and gives a symmetric mount, and the rear rod can carry a tool or sensor flag. At 0.5 MPa the usable working thrust is about 3534 N once you plan at 60% of rating, which is roughly a 360 kg vertical load with margin. Ports are 1/4" (PT), the rod end is male thread (B code), a fixed TPU bumper sits at each end, and speed runs 30-500 mm/s. Note that no magnet is fitted on this code; order the optional -S version if you need CMSE / DMSE switch sensing.

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 ACED125X300B Is Used
Heavy press and forming fixtures
With 5890.5 N available in both directions at 0.5 MPa, the through-rod can clamp or eject on either end of a stamping or forming jig, and the short ISO 21287 body fits where a full-length profile cylinder cannot.
Vertical lift-and-lower stations
The rod-side area gives the same force pushing up and pulling down, so a pallet or die cart of roughly 300 kg can be raised with a 2:1 margin; add a pilot check valve because the piston will drift if air is lost.
Conveyor pusher and divert gates
The rear rod doubles as a mount point for a gate or flag, and the fixed TPU bumper at both ends absorbs the stop at 30-500 mm/s speeds on heavy parcel or tote diverters.
Is the Airtac ACED Double-acting Compact Cylinder ACED125X300B the Right Cylinder?
At 125 mm bore this is the top of the ACED range: 5890.5 N at 0.5 MPa and 8246.7 N at 0.7 MPa, equal in both directions. If your load needs less than 3769.9 N, the ACED100X300B saves space and air; if you need more thrust, move to a larger bore series. The 300 mm stroke is the maximum standard stroke for this bore, so no made-to-order length is needed. Remember the piston drifts if air is lost - add a rod lock or pilot check valve for held loads. Mount with FA/FB flanges, LB foot or FTC brackets, and specify the -S code if CMSE / DMSE position sensing is required.
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 ACED125X300B 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, with a peak 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, temperature -20 to +70 C, and the port is 1/4" PT with a male rod thread (B code).
The hard-anodized aluminium ISO 21287 body saves about 50% of the mounting length of an ISO 15552 profile cylinder, and FA/FB flange, LB foot or FTC brackets bolt straight to the standard face. Sensing is not fitted on this code: the magnet is the optional -S version, which accepts CMSE / DMSE switches. A fixed TPU bumper at each end absorbs end-of-stroke energy, and confirm exact outline dimensions from the datasheet.
