Airtac ACED Double-acting Compact Cylinder ACED125X30SB
The AirTAC Airtac ACED Double-acting Compact Cylinder ACED125X30SB is a genuine double acting, double rod ISO 21287 compact air cylinder with a Ø125mm bore and 30mm 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 ACED125X30SB
A double acting compact cylinder built to ISO 21287, the ACED125X30SB pushes a 25 mm rod out of BOTH covers, so its 5890.5 N at 0.5 MPa is identical on the extend and retract stroke. The 125 mm bore reaches 8246.7 N at 0.7 MPa and up to 1201.3 kgf at 1.0 MPa, placing it at the top of the ACE range for heavy clamping and press work. Because the through-rod exits each end, the piston resists rotation and the rear rod can carry a sensor flag or a second tool.
The hard-anodized aluminium body is roughly 50% shorter in mounting length than an ISO 15552 profile cylinder, so this big bore still fits into presses and gantries with tight daylight openings. A fixed TPU bumper at each end absorbs end-of-stroke shock, and the male rod thread (B code) bolts straight to your tooling. With the -S magnet fitted on this model, CMSE / DMSE switches can be mounted anywhere along the body slots. As a rule of thumb, plan on about 3534 N of usable work at 0.5 MPa, which lifts roughly 180 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 ACED125X30SB Is Used
Heavy press and staking station
The 5890.5 N both-ways force at 0.5 MPa stakes bushings or crimps terminals in automotive bracket assembly, with the short ISO 21287 body fitting inside the press frame.
Reciprocating lift-and-lower gantry
Equal force in both directions makes the through-rod ideal for a vertical counterweight arm lifting about 180 kg parts pallets, with CMSE switches tracking position via the fitted magnet.
Dual-side fixture clamping
A rod at each cover lets one cylinder clamp a steel weldment from both faces in a machining fixture, the male thread taking an I knuckle for angular contact.
Is the Airtac ACED Double-acting Compact Cylinder ACED125X30SB the Right Cylinder?
At 125 mm bore this is the largest ACED size; if 5890.5 N at 0.5 MPa is more than the job needs, the 100 mm bore delivers 3769.9 N and the 80 mm bore 2356.2 N at the same pressure. The 30 mm stroke is well inside the 300 mm maximum standard stroke for this bore, so it ships as a standard build. Remember the piston drifts if air is lost - for a held load add a rod lock or pilot check valve. FA/FB flanges, LB feet and FTC brackets mount on the ISO 21287 face, and I/Y rod knuckles suit 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 ACED125X30SB FAQ
Because a rod exits both covers, output is equal both ways: 5890.5 N at 0.5 MPa and 8246.7 N at 0.7 MPa on the extend and retract stroke alike, 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, with a fixed TPU bumper at each end.
The ACED125X30SB carries the optional -S magnet, so CMSE reed or DMSE solid-state switches clamp into the body slots for end-of-stroke or mid-stroke signalling. Note the cylinder does not hold position if air pressure is lost - use a rod lock or pilot check valve where a load must stay put.
