Airtac ACED Double-acting Compact Cylinder ACED125X25SB
The AirTAC Airtac ACED Double-acting Compact Cylinder ACED125X25SB is a genuine double acting, double rod ISO 21287 compact air cylinder with a Ø125mm bore and 25mm 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 ACED125X25SB
A double acting, double-rod compact cylinder built to ISO 21287, the ACED125X25SB pushes a 125 mm bore through a short 25 mm stroke and delivers 5890.5 N in BOTH directions at 0.5 MPa, because a rod exits each cover and both strokes work on the rod-side area. The B code gives a male rod thread on each end, and the 1/4" port matches the 125 mm bore. At 0.7 MPa the same piston reaches 8246.7 N either way, topping out at 1201.3 kgf at 1.0 MPa.
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 it slots into heavy presses and gantries where a full-length body cannot. As a rule of thumb, plan on roughly 3534 N of real work at 0.5 MPa, which lifts about 360 kg vertically with a 2:1 margin. A fixed TPU bumper at each end absorbs end-of-stroke shock, and the fitted -S magnet accepts CMSE / DMSE switches.

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 ACED125X25SB Is Used
Short-stroke press station
A 25 mm stroke and 5890.5 N both ways at 0.5 MPa suits staking or marking heads on aluminium extrusion lines, where the compact body fits inside the press frame.
Reciprocating clamp carriage
Equal force in both directions makes this cylinder ideal for a sliding clamp on a machining fixture that grips and releases with identical force, guided by the through-rod.
Position-flagged heavy gate
With the -S magnet fitted, CMSE / DMSE switches report open/closed on a heavy conveyor gate or diverter, while the back-end rod carries a position flag.
Is the Airtac ACED Double-acting Compact Cylinder ACED125X25SB the Right Cylinder?
For a 25 mm stroke at this force class, compare the 100 mm bore (3769.9 N at 0.5 MPa) if your load is lighter, or step up only if you need the full 5890.5 N both ways. Remember the through-rod does not hold position when air is lost - for a suspended load add a rod lock or pilot check valve. FA/FB flange, LB foot and FTC brackets plus I/Y rod knuckles bolt to the ISO 21287 face; the male rod thread (B) suits clevis-style tooling. The -S magnet is already fitted on this code, so CMSE / DMSE switches mount directly.
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 ACED125X25SB FAQ
Because it is a double-rod cylinder, output is equal both ways: 5890.5 N at 0.5 MPa and 8246.7 N at 0.7 MPa on each stroke (rod-side area both sides), 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, -20 to +70 C.
The ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, with a fixed TPU bumper at each end and FA/FB, LB and FTC mounting options. The S means the optional -S magnet is fitted on this model, so CMSE / DMSE switches can be clipped to the body; the B means a male rod thread on both rod ends. Port is 1/4" PT.
