Airtac ACED Double-acting Compact Cylinder ACED125X200S
The AirTAC Airtac ACED Double-acting Compact Cylinder ACED125X200S is a genuine double acting, double rod ISO 21287 compact air cylinder with a Ø125mm bore and 200mm 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 ACED125X200S
A heavy-duty double acting compact cylinder built to ISO 21287, the ACED125X200S pushes a 125 mm bore through a 200 mm stroke with a rod leaving both covers. Because each side works on the rod-side area, output is identical in both directions: 5890.5 N at 0.5 MPa and 8246.7 N at 0.7 MPa. The hard-anodized aluminium body carries magnet slots along its full length, and the -S code on this model means the magnet is fitted, so CMSE or DMSE switches can be clipped on anywhere along the travel.
The through-rod resists rotation and side load and gives a symmetric mounting face at each end, which suits heavy clamping bridges and synchronized tooling. Its short ISO 21287 body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into presses and gantries where a full-length body will not fit. As a sizing guide, the 5890.5 N rating at 0.5 MPa translates to roughly 600 kg of vertical lift, or about 300 kg with a 2:1 margin. A fixed TPU bumper at each end absorbs end-of-stroke shock, and the S45C hard-chrome plated 25 mm rod stands up to continuous duty.

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 ACED125X200S Is Used
Heavy clamp bridges on welding fixtures
The through-rod clamps a car-body panel fixture from both sides with equal 5890.5 N force, and the short body fits inside the fixture frame where a full-length profile cylinder would collide with the tooling.
Stamping press part ejection
With about 600 kg of vertical lift equivalent at 0.5 MPa, the double rod ejects stamped steel brackets from a die on both strokes, while the back-end rod carries a sensor flag for position feedback via CMSE switches.
Pallet stacker press-down station
In a packaging line the symmetric rod mount guides a press plate down onto stacked cartons with 8246.7 N at 0.7 MPa, and the fixed TPU bumpers soften the bottom-of-stroke impact at 30-500 mm/s.
Is the Airtac ACED Double-acting Compact Cylinder ACED125X200S the Right Cylinder?
At this force class you are near the top of the ACE range. If 5890.5 N at 0.5 MPa is more than the job needs, the ACED100X200 delivers 3769.9 N from a 100 mm bore; if you need more, the 125 mm bore is the largest standard option. Stroke 200 mm sits inside the 300 mm maximum standard stroke for this bore, so no made-to-order build is required. Plan on roughly 3534 N of usable work at 0.5 MPa rather than the full rating, and remember the piston will drift if air is lost - add a rod lock or pilot check where a load must be held. FA/FB flanges, LB feet and FTC brackets bolt straight to the ISO 21287 face, and the female M16x2.0 rod thread accepts standard knuckles.
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 ACED125X200S FAQ
Yes - the double-rod design puts a rod through both covers, so both strokes use the rod-side area and force is equal either way: 5890.5 N at 0.5 MPa and 8246.7 N at 0.7 MPa, peaking at about 1201.3 kgf at 1.0 MPa. Operating range is 0.15-1.0 MPa (22-145 psi) with 1.5 MPa (215 psi) proof pressure, air filtered to 40 um, speed 30-500 mm/s, and temperature -20 to +70 C.
The S means the optional -S magnet is fitted on this unit, so AirTAC CMSE or DMSE reed or solid-state switches can be mounted in the slots along the hard-anodized aluminium body; models without the S code carry no magnet. The ISO 21287 compact body is about 50% shorter in mounting length than an ISO 15552 profile cylinder, the 25 mm S45C rod is hard-chrome plated, and fixed TPU bumpers at both ends absorb end-of-stroke energy.
