Airtac ACED Double-acting Compact Cylinder ACED40X40B
The AirTAC Airtac ACED Double-acting Compact Cylinder ACED40X40B is a genuine double acting, double rod ISO 21287 compact air cylinder with a Ø40mm bore and 40mm stroke, 1/8" 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 ACED40X40B
Double acting with a rod leaving both covers, the ACED40X40B pushes and pulls with the same 571.8 N at 0.5 MPa because each stroke works on the rod-side area. The 40 mm bore and 40 mm stroke suit short, symmetric strokes in tight fixtures, running at 30-500 mm/s on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi).
The ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into guarded pick stations where a full-length body will not fit. A hard-anodized aluminium body carries an S45C hard-chrome rod, and a fixed TPU bumper sits at each end. For positioning, plan on roughly 343 N of usable work at 0.5 MPa, which is about 35 kg held 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 ACED40X40B Is Used
Symmetric clamp fixture
The through-rod lets a machining fixture clamp from both sides of a 40 mm stroke with one cylinder, delivering 571.8 N each way at 0.5 MPa without a second body.
Packaging pusher station
A rear rod on the 12 mm shaft carries a sensor flag or second pusher pad, while the short ISO 21287 body fits under a low conveyor guard.
Lift-assist elevator jig
With about 35 kg of vertical capacity at a 2:1 margin, the double rod resists rotation while raising a small pallet nest on a 40 mm lift.
Is the Airtac ACED Double-acting Compact Cylinder ACED40X40B the Right Cylinder?
At 571.8 N per direction, this 40 mm bore sits between the 32 mm size (345.6 N) and the 50 mm size (881.2 N) at 0.5 MPa, so step up if your tooling mass climbs past about 35 kg on a vertical axis. Remember the piston drifts if air is lost - add a rod lock or pilot check for a held load. The B code gives a male M8x1.25 rod thread, FA/FB flange or LB foot mount to the ISO 21287 face, and the optional -S magnet enables CMSE / DMSE switches; this unit has no magnet fitted.
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 ACED40X40B FAQ
Because a rod exits both covers, force is equal in both directions: 571.8 N at 0.5 MPa and 800.5 N at 0.7 MPa, with a maximum of 116.6 kgf at 1.0 MPa. Both strokes use the rod-side area, so there is no push-versus-pull difference. Operating range is 0.15-1.0 MPa (22-145 psi) with proof pressure of 1.5 MPa (215 psi).
The ISO 21287 body is roughly 50% shorter in mounting length than an ISO 15552 profile cylinder, and the 40 mm bore takes a 1/8" port with a 12 mm rod. A fixed TPU bumper at each cover absorbs end-of-stroke energy; it is not adjustable and never holds a load. Mounting brackets bolt to the standard face, and the optional -S magnet allows CMSE / DMSE switch mounting - without -S no magnet is fitted.
