Airtac ACED Double-acting Compact Cylinder ACED40X40S
The AirTAC Airtac ACED Double-acting Compact Cylinder ACED40X40S 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 ACED40X40S
The ACED40X40S is a double acting, double-rod ISO 21287 compact cylinder: a piston rod exits both covers, so output force is equal in both directions because each stroke works on the rod-side area. At 0.5 MPa it delivers 571.8 N either way, rising to 800.5 N at 0.7 MPa. The 40 mm bore and 40 mm stroke suit short, symmetric moves where a rod on both ends is genuinely useful.
The hard-anodized aluminium body with an S45C hard-chrome-plated rod runs at 0.15-1.0 MPa (22-145 psi) and 30-500 mm/s, with a fixed TPU bumper at each end. Because the body is about 50% shorter than an ISO 15552 profile cylinder, it drops into tight jigs and guarding. The through-rod resists rotation and light side load, and the rear rod can carry a sensor flag. This S-coded model carries the optional -S magnet, so CMSE / DMSE switches mount directly on the body slots. As a rule of thumb, plan on roughly 343 N of real work at 0.5 MPa (about 0.6 of the rating), which lifts around 17 kg vertically with a 2:1 margin.

|---|---|
| 0.5 MPa | 572 N |

Where the Airtac ACED Double-acting Compact Cylinder ACED40X40S Is Used
Symmetric push-pull jig clamping
A rod on both covers lets one ACED40X40S clamp a steel bracket from the front while the rear rod ejects it, with 571.8 N available in each direction at 0.5 MPa.
Gated assembly station with position feedback
The fitted -S magnet works with CMSE / DMSE switches to confirm end-of-stroke on a 40 mm transfer move inside a guarded cell where the short body saves mounting length.
Conveyor divert with rear sensor flag
The back-end rod carries a flag for a proximity sensor while the front rod pushes cartons off a line at 30-500 mm/s, both strokes delivering equal 800.5 N force at 0.7 MPa.
Is the Airtac ACED Double-acting Compact Cylinder ACED40X40S the Right Cylinder?
For this 40 mm bore, a 32 mm ACED gives 345.6 N at 0.5 MPa both ways, while stepping up to a 50 mm bore raises it to 881.2 N - so choose the 40 when your load sits between roughly 200 and 340 N of working demand. Remember the piston drifts if air is lost; for a held load add a rod lock or pilot check valve. Mount with FA/FB flange, LB foot or FTC brackets plus I/Y rod knuckles on the ISO 21287 face, and keep the S magnet in mind if CMSE / DMSE position feedback is planned 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 ACED40X40S FAQ
Yes - because a rod exits both covers, both strokes use the rod-side area, so output is equal either way: 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. Operating range is 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), speed 30-500 mm/s, air filtered to 40 um, temperature -20 to +70 C.
The ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it fits shallow gantries and guarded slides. This model carries the optional -S magnet, so CMSE / DMSE reed or solid-state switches clip into the body slots for end-of-stroke signalling. A fixed TPU bumper at each end absorbs end-of-stroke energy, and FA/FB flange, LB foot or FTC mounts bolt straight to the standard face.
