Airtac ACED Double-acting Compact Cylinder ACED125X250SB
The AirTAC Airtac ACED Double-acting Compact Cylinder ACED125X250SB is a genuine double acting, double rod ISO 21287 compact air cylinder with a Ø125mm bore and 250mm 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 ACED125X250SB
The ACED125X250SB is a double acting, double-rod compact cylinder built to the ISO 21287 short-body format. A 25 mm hard-chrome-plated S45C rod exits both covers, so thrust is identical on each stroke: 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. The male rod thread (B code) suits clevis-style tooling, and the fitted -S magnet lets CMSE or DMSE switches report position without any external flag.
Because the through-rod resists rotation and side load while giving a symmetric mount, this 125 mm bore unit suits heavy presses, clamps and lift stations. The short ISO 21287 body saves about 50% of the mounting length of an ISO 15552 profile cylinder, freeing space in guarded machines. A fixed TPU bumper at each end absorbs end-of-stroke shock, and the back-end rod can carry a tooling plate or sensor target. At 0.5 MPa the usable working thrust is roughly 3534 N, which corresponds to lifting about 360 kg vertically - halve that for a 2:1 margin on a real hoist.

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 ACED125X250SB Is Used
Heavy stamping press ejector
The equal 5890.5 N thrust on both strokes ejects formed steel panels from a die and retracts with identical force, while the 250 mm stroke clears deep die pockets.
Pallet strapper tension arm
A through-rod on both ends lets the tension roller mount between two rods, resisting the side load of PET strapping at up to 360 kg vertical equivalent.
Automotive lift-and-locate station
The symmetric double-rod mount raises a 180 kg car-door fixture with a 2:1 margin, and the fitted -S magnet feeds CMSE switch signals to the PLC at both ends of travel.
Is the Airtac ACED Double-acting Compact Cylinder ACED125X250SB the Right Cylinder?
Step down to the ACED100X250SB if 3769.9 N at 0.5 MPa covers the job, or step up only if more than 5890.5 N is needed, since bore 125 is the largest in the ACED range. The 250 mm stroke sits inside the 300 mm maximum standard stroke for this bore, so no made-to-order barrel is required. Run it on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi), 30-500 mm/s, from -20 to +70 C. Note 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 straight to the ISO 21287 face, and I/Y rod knuckles pair with the male 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 ACED125X250SB FAQ
Yes - as a double-rod cylinder both strokes use the rod-side area, so force is equal both ways: 5890.5 N at 0.5 MPa and 8246.7 N at 0.7 MPa, peaking at 1201.3 kgf at 1.0 MPa. Operating range is 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), speed 30-500 mm/s, fluid air filtered to 40 um, temperature -20 to +70 C. The 25 mm rod carries a male thread and the port is 1/4" PT.
It is an ISO 21287 compact cylinder with a hard-anodized aluminium body about 50% shorter in mounting length than an ISO 15552 profile cylinder, threaded aluminium covers, a hard-chrome-plated S45C rod on both ends and a fixed TPU bumper at each stroke end. This model carries the optional -S magnet, so CMSE reed or DMSE solid-state switches can be clipped into the body slots for end-of-stroke signalling; FA/FB flange, LB foot and FTC mounting plus I/Y rod knuckles bolt to the standard face.
