Airtac ACED Double-acting Compact Cylinder ACED125X45
The AirTAC Airtac ACED Double-acting Compact Cylinder ACED125X45 is a genuine double acting, double rod ISO 21287 compact air cylinder with a Ø125mm bore and 45mm 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 ACED125X45
A double acting compact cylinder built to ISO 21287, the ACED125X45 pushes a 125 mm bore through a 45 mm stroke with a rod leaving both covers, so thrust is identical on each stroke: 5890.5 N at 0.5 MPa and 8246.7 N at 0.7 MPa. The through-rod on the rear cover resists rotation and side load and can carry a sensor flag or a second tooling plate. Running range is 0.15-1.0 MPa (22-145 psi) with a 1.5 MPa (215 psi) proof rating, at 30-500 mm/s.
The hard-anodized aluminium body with an S45C hard-chrome plated rod saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, which matters when a 125 mm bore has to live inside a press frame or clamp fixture. A fixed TPU bumper at each end absorbs end-of-stroke shock. For a vertical lift, treat about 3534 N (0.6 of the rating) as the working figure - roughly 360 kg of real load - and the raw thrust equates to about 300 kg lifted 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 ACED125X45 Is Used
Heavy press-fit stations
The 5890.5 N through-stroke presses bearings or bushings into housings on an automotive assembly line, with the 45 mm stroke matching short press ram travel.
Clamp fixtures on machining centres
The short ISO 21287 body tucks a 125 mm bore inside a CNC fixture base, clamping castings at 8246.7 N when supplied at 0.7 MPa.
Balanced slide actuation
A rod on both covers drives a heavy conveyor gate or lifting table symmetrically, equal force each way and the rear rod carrying a position flag.
Is the Airtac ACED Double-acting Compact Cylinder ACED125X45 the Right Cylinder?
At 5890.5 N per direction, this bore sits near the top of the ACED range; step down to the 100 mm bore (3769.9 N at 0.5 MPa) for lighter clamps or up to nothing larger - 125 mm is the biggest standard bore. The 45 mm stroke is well inside the 300 mm maximum standard stroke for this bore. Remember the piston drifts if air is lost, so add a rod lock or pilot check valve for a held load. Mounting bolts to the ISO 21287 face: FA/FB flange, LB foot or FTC brackets with I/Y rod knuckles. The rod here is female M16x2.0 with a PT port; add the optional -S magnet if CMSE or DMSE switches are needed later.
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 ACED125X45 FAQ
Yes - the double-rod design means both strokes use the rod-side area, so output 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 1.5 MPa (215 psi), speed 30-500 mm/s, air filtered to 40 um, temperature -20 to +70 C. Port is 1/4" PT and the rod thread is female M16x2.0.
It is an ISO 21287 compact cylinder - the hard-anodized aluminium body is about 50% shorter in mounting length than an ISO 15552 profile cylinder. Fixed TPU bumpers at both ends absorb end-of-stroke impact. FA/FB flange, LB foot and FTC mounts plus I/Y knuckles bolt to the standard face. Position sensing requires the optional -S magnet code; this unit has no magnet fitted, so order ACED125X45S to run CMSE or DMSE switches.
