Airtac ACED Double-acting Compact Cylinder ACED125X90B
The AirTAC Airtac ACED Double-acting Compact Cylinder ACED125X90B is a genuine double acting, double rod ISO 21287 compact air cylinder with a Ø125mm bore and 90mm 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 ACED125X90B
A double acting ISO 21287 compact cylinder with a rod leaving both covers, the ACED125X90B delivers 5890.5 N in either direction at 0.5 MPa (8246.7 N at 0.7 MPa) because both strokes work on the rod-side area. The 125 mm bore turns roughly 600 kgf of thrust; halve that for a 2:1 margin and it lifts about 300 kg vertically, which suits heavy clamping and press-fit work. The male rod thread (B code) bolts straight to your tooling.
The hard-anodized aluminium body with a burnished bore carries an S45C hard-chrome plated 25 mm rod, and the short ISO 21287 body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it fits deep into presses and gantries. A fixed TPU bumper at each end absorbs end-of-stroke shock, the through-rod resists rotation and side load, and speed runs 30-500 mm/s 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.
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 ACED125X90B Is Used
Press-fit stamping station
With 5890.5 N available in both directions at 0.5 MPa, the 125 mm bore presses bearings into housings on an automotive assembly line and retracts with equal force to strip the tool.
Heavy fixture clamping on a machining centre
The short ISO 21287 body tucks inside a closed machining fixture, and the male-threaded 25 mm rod drives a clamp arm that holds a cast-iron manifold during milling.
Counterbalanced lift column
A rod on each cover gives a symmetric mount for a vertical lift column raising about 300 kg of tooling with a 2:1 margin, while the through-rod resists the side load of an off-centre payload.
Is the Airtac ACED Double-acting Compact Cylinder ACED125X90B the Right Cylinder?
At this force class the next step down is the 100 mm bore at 3769.9 N @0.5 MPa; if you need more, the 125 mm bore is the largest in the ACED range at 5890.5 N @0.5 MPa. The 90 mm stroke sits well inside the 300 mm maximum standard stroke for this bore, so no made-to-order build is needed.
Remember that a plain double-rod cylinder drifts when air is lost - pair it with a rod lock or pilot check if the load must stay put. Mounting brackets such as FA/FB flanges, LB feet and FTC feet bolt to the ISO 21287 face, and I/Y rod knuckles suit the male thread. If you need position sensing, order the -S variant: without the optional -S magnet no CMSE or DMSE switch can be read.
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 ACED125X90B FAQ
Because a rod exits both covers, output is equal both ways: 5890.5 N at 0.5 MPa and 8246.7 N at 0.7 MPa on every stroke (rod-side area). At the full 1.0 MPa rating the cylinder reaches about 1201.3 kgf of thrust. Operating range is 0.15-1.0 MPa (22-145 psi) with proof pressure of 1.5 MPa (215 psi), speed 30-500 mm/s, and air filtered to 40 um.
It is an ISO 21287 compact build - a hard-anodized aluminium body about 50% shorter in mounting length than an ISO 15552 profile cylinder - with a 25 mm hard-chrome S45C rod, male thread (B code), 1/4" PT ports and a fixed TPU bumper at each end. Position sensing requires the optional -S magnet: order ACED125X90BS and CMSE or DMSE switches will read along the body slots; the base model carries no magnet.
