About the Airtac ACED Double-acting Compact Cylinder ACED40X5S
The ACED40X5S is a double acting, double-rod compact cylinder built to the ISO 21287 short-body format, with a 40 mm bore and a very short 5 mm stroke. A piston rod exits both covers, so the through-rod resists rotation and side load while giving a symmetric mount; output force is equal in both directions because both strokes work 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. Air supply is 0.15-1.0 MPa (22-145 psi), speed range 30-500 mm/s, and a fixed TPU bumper sits at each end to absorb end-of-stroke shock.
The hard-anodized aluminium body is about 50% shorter in mounting length than an ISO 15552 profile cylinder, which is exactly what a 5 mm stroke calls for: a nudge, clamp or eject action inside a tight fixture. This model carries the optional -S magnet, so CMSE or DMSE reed or solid-state switches can be clipped onto the body slot to flag both end positions. In practice, plan on roughly 343 N of real work at 0.5 MPa (about 60% of the rating), and note the rod-side area equates to lifting about 29 kg vertically with a 2:1 margin. The S45C hard-chrome rod and female M8x1.25 thread suit standard tooling plates.

Where the Airtac ACED Double-acting Compact Cylinder ACED40X5S Is Used
PCB test fixture clamping
A 5 mm stroke is ideal for pressing a test head or hold-down clamp onto a circuit board; 571.8 N at 0.5 MPa seats the fixture without crushing, and the -S magnet confirms clamp and release.
Gate pin ejection on assembly lines
Short eject or reject-pin actions on conveyor gating need only a few millimetres of travel; the through-rod keeps the pin aligned under side load and both end positions are switchable.
Label press roller on packaging machines
A brief press of a coding or labelling roller against a moving pack suits the 5 mm stroke; about 29 kg vertical-lift equivalent gives a 2:1 margin for spring-loaded roller heads.
Is the Airtac ACED Double-acting Compact Cylinder ACED40X5S the Right Cylinder?
At 5 mm stroke this is a positioning and nudge cylinder, not a travel actuator. If 571.8 N at 0.5 MPa is more than the job needs, the ACED32X25 class gives 345.6 N in the same compact format; if you need real travel, step up to the ACED50X25 class at 881.2 N with strokes to 250 mm. Remember a plain double-rod cylinder drifts when air is lost, so add a rod lock or pilot check for a held load. FA/FB flange, LB foot and FTC brackets plus I/Y rod knuckles bolt straight to the ISO 21287 face, and the -S magnet on this model lets CMSE / DMSE switches report both ends of the tiny 5 mm travel.
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 ACED40X5S FAQ
Because a rod exits both covers, both strokes use the rod-side area, so 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. 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 port is 1/8" (PT) on this 40 mm bore.
The ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so the 5 mm stroke unit fits shallow fixtures and slides. The fixed TPU bumper at each end absorbs end-of-stroke shock. This model already carries the optional -S magnet, so CMSE or DMSE reed or solid-state switches mount directly in the body slot; mounting options include FA/FB flange, LB foot and FTC brackets.
