Airtac ACED Double-acting Compact Cylinder ACED20X40B
The AirTAC Airtac ACED Double-acting Compact Cylinder ACED20X40B is a genuine double acting, double rod ISO 21287 compact air cylinder with a Ø20mm bore and 40mm stroke, M5×0.8 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 ACED20X40B
The ACED20X40B is a double acting compact cylinder built to ISO 21287, with a piston rod leaving BOTH covers so the 20 mm bore pushes and pulls with the same 117.8 N at 0.5 MPa (164.9 N at 0.7 MPa). The B code gives a male rod thread on each end, and the through-rod resists rotation and light side load while the free back-end rod can carry a sensor flag or a second tool. Its short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight jigs and guarding where a full-length body will not fit.
The hard-anodized aluminium body carries a roller-burnished bore, and the S45C hard-chrome plated rod runs on a two-way seal that stores its own grease. A fixed TPU bumper at each end absorbs end-of-stroke energy, and speed spans 30-500 mm/s at 0.15-1.0 MPa (22-145 psi). For a feel for real capacity: about 70 N of the 0.5 MPa rating is a practical working figure, and the rod lifts roughly 6 kg vertically with a 2:1 margin. AirTAC bores this family from 12 to 125 mm.

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 (Ø20mm)
| Pressure | Force (both ways) |
|---|---|
| 0.5 MPa | 118 N |
| 0.7 MPa | 165 N |
| Max (@1.0 MPa) | 24 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 ACED20X40B Is Used
Symmetric push-pull fixture
A rod on each cover lets one cylinder eject a machined aluminum bracket on the forward stroke and retract a locating pin on the return, both at 117.8 N with no force mismatch.
Small-parts diverter on packaging lines
The 40 mm stroke kicks cartons or blisters off a conveyor at up to 500 mm/s, and the through-rod keeps the pusher plate square without an external guide.
Lab and test-rig actuation
The free rear rod drives a limit flag while the front rod presses test samples, and the M5x0.8 ports keep tubing tidy inside compact instrument enclosures.
Is the Airtac ACED Double-acting Compact Cylinder ACED20X40B the Right Cylinder?
At 117.8 N per direction this 20 mm bore suits light clamping and transfer work; drop to the 16 mm bore (75.4 N at 0.5 MPa) for smaller loads or step up to the 25 mm bore (206.2 N) when you need roughly 75% more push. The 40 mm stroke sits well inside the 100 mm standard limit for this bore, so it ships as a catalog item. If the load must stay put when air is lost, add a rod lock or pilot check - this cylinder drifts on its own. Mounting: FA/FB flange, LB foot or FTC brackets plus I/Y rod knuckles bolt to the ISO 21287 face. This unit has no magnet; order ACED20X40BS if you need CMSE / DMSE switch sensing.
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 ACED20X40B FAQ
Because a rod exits both covers, both strokes use the rod-side area, so force is identical each way: 117.8 N at 0.5 MPa and 164.9 N at 0.7 MPa. At the 1.0 MPa maximum the bore reaches about 24 kgf. Operating pressure is 0.15-1.0 MPa (22-145 psi) with 1.5 MPa (215 psi) proof pressure, air filtered to 40 um, -20 to +70 C, and speed of 30-500 mm/s.
It is an ISO 21287 compact cylinder with a hard-anodized aluminium body, S45C hard-chrome rod, threaded aluminium covers and a fixed TPU bumper at each end - about 50% shorter in mounting length than an ISO 15552 profile cylinder. Sensing is optional: this code has no magnet, so order ACED20X40BS to enable CMSE / DMSE switches in the body slots. FA/FB flange, LB foot and FTC mounts plus I/Y knuckles fit the standard face.
