Airtac ACED Double-acting Compact Cylinder ACED125X125SB
The AirTAC Airtac ACED Double-acting Compact Cylinder ACED125X125SB is a genuine double acting, double rod ISO 21287 compact air cylinder with a Ø125mm bore and 125mm 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 ACED125X125SB
A heavy-duty double acting compact cylinder built to ISO 21287, the ACED125X125SB pushes a 25 mm hard-chrome S45C rod out of BOTH covers, so thrust is identical on the extend and return strokes: 5890.5 N at 0.5 MPa and 8246.7 N at 0.7 MPa in either direction. The male rod thread (B code) bolts straight to your tooling, and the 125 mm bore sits in the top force class of the range at 1201.3 kgf maximum.
The hard-anodized aluminium body is roller-burnished inside and threaded to aluminium-alloy covers, cutting mounting length by roughly half compared with an ISO 15552 profile cylinder - useful when a 300 mm-class press or clamp must fit inside a guarded weld cell. A fixed TPU bumper at each end absorbs end-of-stroke shock, and because this model carries the optional -S magnet, CMSE or DMSE switches can be clipped into the body slots for end-position feedback. Running 0.15-1.0 MPa (22-145 psi) at 30-500 mm/s, it lifts about 300 kg vertically with a 2:1 margin (600 kgf raw at 0.5 MPa), and a realistic working budget of about 3534 N leaves headroom for friction and side load.

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 ACED125X125SB Is Used
Heavy fixture clamping on machining centres
5890.5 N at 0.5 MPa from both rod ends lets one cylinder clamp a cast-iron housing from two sides inside a tight CNC fixture, with the short ISO 21287 body fitting where a full-length profile cylinder will not.
Vertical lift-assist in a stamping plant
With about 600 kgf available at 0.5 MPa, the 125 mm bore raises a 300 kg steel blank on a balanced double-rod mast at up to 500 mm/s, the male thread taking the lifting arm directly.
Bench press for bushing insertion
8246.7 N at 0.7 MPa presses bronze bushings into aluminium housings on a production bench, the fixed TPU bumpers softening each stroke end while CMSE switches confirm full retraction.
Is the Airtac ACED Double-acting Compact Cylinder ACED125X125SB the Right Cylinder?
Size up or down by force: the 100 mm bore ACED gives 3769.9 N at 0.5 MPa, while this 125 mm bore delivers 5890.5 N - a 56% jump for heavy clamps and presses. If your fixture needs rotation-proof guidance or a rear sensor flag, the through-rod on both covers is exactly what a single-rod ACE cannot offer. Mount with FA/FB flanges, LB feet or FTC brackets plus I/Y rod knuckles on the ISO 21287 face. 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. Stroke 125 mm is within the 300 mm standard range for this bore, and the 1/4" PT ports suit higher-flow circuits.
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 ACED125X125SB FAQ
Yes - the double-rod design means a rod exits both covers, so both strokes use the rod-side area. Output is 5890.5 N at 0.5 MPa and 8246.7 N at 0.7 MPa in either direction, with a maximum of 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, air filtered to 40 um, temperature -20 to +70 C.
S means the optional -S magnet is fitted on this unit, so CMSE or DMSE reed or solid-state switches can be mounted in the body slots (units ordered without S have no magnet). B means a male rod thread on both 25 mm rods; the ports are 1/4" PT. The compact ISO 21287 body is hard-anodized aluminium with aluminium-alloy covers and a fixed TPU bumper at each end, saving about 50% of the mounting length of an ISO 15552 profile cylinder.
