Airtac ACED Double-acting Compact Cylinder ACED125X75SB
The AirTAC Airtac ACED Double-acting Compact Cylinder ACED125X75SB is a genuine double acting, double rod ISO 21287 compact air cylinder with a Ø125mm bore and 75mm 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 ACED125X75SB
A double acting compact cylinder built to ISO 21287, the ACED125X75SB pushes a 125 mm bore through a 75 mm stroke with a rod leaving BOTH covers. Because each side works on the rod-side area, output is a matched 5890.5 N at 0.5 MPa and 8246.7 N at 0.7 MPa in either direction - no push/pull mismatch to design around. The male rod thread (B code) and PT ports are ready for standard fittings, and the through-rod resists rotation while the rear rod can carry a sensor flag.
The hard-anodized aluminium body with an S45C hard-chrome rod shrinks the mounting length to roughly half that of an ISO 15552 profile cylinder, so heavy clamping fits inside tight presses, weld fixtures and gantries. A fixed TPU bumper at each end absorbs end-of-stroke shock, and this -S model carries the optional magnet, so CMSE / DMSE switches mount directly on the body slots. At 0.5 MPa, plan on about 3534 N of usable work, which corresponds to lifting 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 ACED125X75SB Is Used
Heavy press-fit clamping
Delivers 5890.5 N at 0.5 MPa from each rod end to seat bearings or press bushings into housings on a short-stroke assembly press, where the compact body fits between platens.
Weld fixture hold-down
The symmetric through-rod clamps thick steel panels from both sides in an automotive weld cell, with CMSE switches on the -S magnet confirming clamp closure before the weld sequence fires.
Pallet pusher on a conveyor
A 75 mm stroke is enough to kick pallets across a transfer line, and the 180 kg vertical-lift equivalent at 0.5 MPa gives ample margin for heavy loads pushed horizontally.
Is the Airtac ACED Double-acting Compact Cylinder ACED125X75SB the Right Cylinder?
At 5890.5 N per stroke at 0.5 MPa, this 125 mm bore sits near the top of the ACED range - step down to the 100 mm bore (3769.9 N) for lighter clamps or up to nothing larger, as 125 mm is the biggest bore offered. The 75 mm stroke is well inside the 300 mm maximum standard stroke for this bore, so it ships as a catalog item. Remember 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. FA/FB flanges, LB feet, CA/CB clevises and FTC brackets bolt straight to the ISO 21287 face, and the -S magnet on this model accepts CMSE / DMSE position switches without modification.
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 ACED125X75SB FAQ
Yes - the double-rod design exposes the rod-side area on both strokes, so force is identical each way: 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 75 mm stroke sits well within the 300 mm maximum standard stroke for a 125 mm bore.
The hard-anodized aluminium ISO 21287 body cuts mounting length to about half of an ISO 15552 profile cylinder, so a 125 mm bore fits where a full-length cylinder cannot. This SB model carries the -S magnet and a male rod thread, so CMSE / DMSE reed or solid-state switches snap into the body slots for end-of-stroke or mid-stroke detection, and a fixed TPU bumper at each end absorbs the piston's arrival.
