Airtac ACED Double-acting Compact Cylinder ACED20X55S
The AirTAC Airtac ACED Double-acting Compact Cylinder ACED20X55S is a genuine double acting, double rod ISO 21287 compact air cylinder with a Ø20mm bore and 55mm 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 ACED20X55S
A double acting compact cylinder with a rod leaving both covers, the ACED20X55S delivers 117.8 N in each direction at 0.5 MPa because both strokes work on the rod-side area. The 20 mm bore and 55 mm stroke suit small clamping and transfer heads, and the through-rod on the rear cover can carry a sensor flag or a second tooling plate. With the -S magnet fitted, CMSE or DMSE reed and solid-state switches mount directly in the body slots.
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. Its short ISO 21287 body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight fixtures. For sizing, treat roughly 70 N (0.6 of the rated push) as usable work force, which is about 3.6 kg of vertical lift 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 (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 ACED20X55S Is Used
Small-parts ejection in plastic molding
The symmetric 117.8 N push and pull ejects finished nylon fittings from shallow cavities, with the 55 mm stroke clearing the part in one move.
Position-flagged gate on a bottling line
With the -S magnet fitted, CMSE switches confirm gate open and closed on a 55 mm divert stroke, and the rear rod carries a second flag for a redundant check.
Pusher arm on electronics conveyor
The through-rod resists rotation as the arm sweeps PCB trays sideways at 30-500 mm/s, and the compact body fits under the guard rail where a full-length cylinder will not.
Is the Airtac ACED Double-acting Compact Cylinder ACED20X55S the Right Cylinder?
At 117.8 N per side at 0.5 MPa, this 20 mm bore sits between the 16 mm ACED (75.4 N) and the 25 mm ACED (206.2 N); step up if your jig needs more grip. The 55 mm stroke is well inside the 100 mm standard limit for this bore, so no made-to-order build is needed. FA/FB flanges, LB feet and FTC brackets bolt to the ISO 21287 face, and the female M6x1.0 rod thread accepts standard knuckles. Note that the piston drifts if air is lost - add a rod lock or pilot check where a load must stay put.
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 ACED20X55S FAQ
Because a rod exits both covers, force is equal in both directions: 117.8 N at 0.5 MPa and 164.9 N at 0.7 MPa on each stroke, peaking at 24.0 kgf (240 N class) at 1.0 MPa. Operating range is 0.15-1.0 MPa (22-145 psi) with a 1.5 MPa (215 psi) proof pressure, air filtered to 40 um, speed 30-500 mm/s, and temperature -20 to +70 C.
It is an ISO 21287 compact cylinder with a hard-anodized aluminium body and S45C hard-chrome rod, about 50% shorter in mounting length than an ISO 15552 profile cylinder. A fixed TPU bumper at each end absorbs end-of-stroke impact. The -S magnet on this model lets you fit CMSE or DMSE switches for stroke-end detection, and the M5x0.8 port keeps plumbing small.
