Airtac ACED Double-acting Compact Cylinder ACED40X125SB
The AirTAC Airtac ACED Double-acting Compact Cylinder ACED40X125SB is a genuine double acting, double rod ISO 21287 compact air cylinder with a Ø40mm bore and 125mm stroke, 1/8" air ports and a hard-anodized aluminium body.

About the Airtac ACED Double-acting Compact Cylinder ACED40X125SB
The ACED40X125SB is a double acting, double-rod ISO 21287 compact cylinder: a piston rod exits both covers, so the 40 mm bore delivers 571.8 N at 0.5 MPa and 800.5 N at 0.7 MPa in EACH direction, because both strokes work on the rod-side area. The B code gives a male rod thread and the S code means the magnet is fitted, so CMSE / DMSE reed or solid-state switches can be clipped onto the body slots right away. Running on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi), it cycles at 30-500 mm/s between -20 and +70 C.
The short ISO 21287 body saves about 50% of the mounting length of an ISO 15552 profile cylinder, which is why this model suits tight pick-and-place gantries and guarded stations. A fixed TPU bumper at each end absorbs end-of-stroke shock, and the through-rod resists rotation and light side load while giving a symmetric mount - the rear rod can even carry a sensor flag. In practice, plan on roughly 343 N (about 35 kg) of usable push at 0.5 MPa, or halve the lift equivalent and it will raise about 17 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 (Ø40mm)
| Pressure | Force (both ways) |
|---|---|
| 0.5 MPa | 572 N |
| 0.7 MPa | 800 N |
| Max (@1.0 MPa) | 117 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 ACED40X125SB Is Used
Symmetric press or stamping nest
Equal 571.8 N force on approach and return lets one ACED40X125SB both seat a bushing into a housing and retract the tooling at the same rated force, with the male threaded rod taking a custom press tip.
Conveyor gate diverter
The through-rod keeps the gate blade square without an anti-rotation guide, and the fitted magnet plus a DMSE switch confirms gate-open and gate-closed from the same cylinder.
Pallet-stacker part lift
With about 17 kg of vertical lift at a 2:1 margin, the 40 mm double-rod raises fixture pallets or cast brackets in a machining cell, the rear rod doubling as a position-flag carrier.
Is the Airtac ACED Double-acting Compact Cylinder ACED40X125SB the Right Cylinder?
At 571.8 N per direction at 0.5 MPa, the 40 mm bore sits between the 32 mm (345.6 N) and 50 mm (881.2 N) double-rod classes - step up to 50 mm if your tooling mass grows, or down to 32 mm for lighter clamps. The 125 mm stroke is well inside the 200 mm standard limit for this bore, so it ships as a catalog item. FA/FB flanges, LB feet and FTC brackets bolt to the ISO 21287 face, and I/Y rod knuckles suit the male threaded rod. Note that like any plain double-rod cylinder it will drift if air is lost - add a rod lock or pilot check where a load must be held.
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 ACED40X125SB FAQ
Yes - because a rod exits both covers, both strokes use the rod-side area of the 40 mm bore. The figures are 571.8 N at 0.5 MPa and 800.5 N at 0.7 MPa in each direction, with a maximum of 116.6 kgf at 1.0 MPa. A practical working figure is about 343 N (roughly 35 kg equivalent) at 0.5 MPa.
It is an ISO 21287 compact cylinder whose short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, with a fixed TPU bumper at each end and FA/FB, LB or FTC mounting on the standard face. The S means the magnet is fitted on this unit, so CMSE or DMSE reed and solid-state switches can be mounted in the body slots without modification.
