Airtac ACED Double-acting Compact Cylinder ACED125X15S
The AirTAC Airtac ACED Double-acting Compact Cylinder ACED125X15S is a genuine double acting, double rod ISO 21287 compact air cylinder with a Ø125mm bore and 15mm 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 ACED125X15S
The ACED125X15S is a double acting, double-rod ISO 21287 compact cylinder: a 25 mm rod exits both covers, so the 125 mm bore delivers the same 5890.5 N at 0.5 MPa (8246.7 N at 0.7 MPa) whether it pushes or pulls. Air supply is 0.15-1.0 MPa (22-145 psi), speed 30-500 mm/s, and the short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, which matters when a 15 mm stroke must fit inside a tight clamp fixture or press frame.
The through-rod resists rotation and side load and gives a symmetric mount, and the rear rod can carry a sensor flag on a clamping station. This -S model carries the optional magnet, so CMSE / DMSE reed or solid-state switches mount directly in the body slots to confirm clamp and unclamp positions. A fixed TPU bumper at each end absorbs end-of-stroke shock, and the hard-anodized aluminium body with S45C hard-chrome rod stands up to high-cycle work. As a rule of thumb, plan on about 3534 N of usable force at 0.5 MPa, which lifts roughly 300 kg vertically with a 2:1 margin.

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 ACED125X15S Is Used
Short-stroke press and clinch stations
A 15 mm stroke with 5890.5 N both ways suits clinching terminals or staking bearings in electronics and appliance assembly, where the compact body fits inside the press head.
Heavy clamp fixtures on machining lines
The symmetric through-rod clamps castings or forgings on CNC fixtures; the rear rod drives a flag past a CMSE switch to prove the part is locked before the cycle starts.
Die and mold positioning slides
About 300 kg of vertical lift capability with a 2:1 margin positions heavy die blocks in stamping or injection tooling, with the short body keeping the slide envelope small.
Is the Airtac ACED Double-acting Compact Cylinder ACED125X15S the Right Cylinder?
At 125 mm bore this is the top of the ACED range: 5890.5 N at 0.5 MPa in both directions, against 3769.9 N for the 100 mm bore if you need slightly less force. The 15 mm stroke is well inside the 300 mm maximum standard stroke for this bore, so it ships as a standard build. Ports are 1/4" (PT) and the female rod thread is M16x2.0. Remember that a plain double-rod cylinder drifts when air is lost, so add a rod lock or pilot check valve if the press or clamp must hold position. FA/FB flange, LB foot and FTC brackets plus I/Y rod knuckles bolt straight to the ISO 21287 face.
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 ACED125X15S FAQ
Because a rod exits both covers, both strokes use the rod-side area and output is equal in both directions: 5890.5 N at 0.5 MPa and 8246.7 N at 0.7 MPa, with a maximum of 1201.3 kgf at 1.0 MPa. Operating pressure is 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), speed 30-500 mm/s, and the fixed TPU bumper at each end absorbs end-of-stroke energy.
It is an ISO 21287 compact cylinder with a hard-anodized aluminium body and S45C hard-chrome plated rod, about 50% shorter in mounting length than an ISO 15552 profile cylinder. FA/FB flanges, LB foot and FTC brackets plus I/Y rod knuckles bolt to the standard face. This -S version carries the optional magnet, so CMSE / DMSE switches can be clipped into the body slots; position is signalled, not held, so use a rod lock or pilot check if the load must stay put when air is lost.
