Airtac ACED Double-acting Compact Cylinder ACED50X20SB
The AirTAC Airtac ACED Double-acting Compact Cylinder ACED50X20SB is a genuine double acting, double rod ISO 21287 compact air cylinder with a Ø50mm bore and 20mm 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 ACED50X20SB
A double acting compact cylinder built to ISO 21287, the ACED50X20SB pushes a 16 mm hard-chrome rod out of BOTH covers, so its 881.2 N output at 0.5 MPa is identical on the extend and retract stroke. The 50 mm bore delivers 1233.7 N at 0.7 MPa and up to 179.7 kgf at 1.0 MPa, with a male rod thread (B code) on each end and a fixed TPU bumper absorbing the stop at both covers.
The short hard-anodized aluminium body saves about 50% of the mounting length of an ISO 15552 profile cylinder, which is why it drops into tight press fixtures and slide assemblies a full-length body cannot enter. The through-rod resists rotation and side load and gives a symmetric mount, and the rear rod can carry a sensor flag. This unit carries the optional -S magnet, so CMSE / DMSE switches mount straight on the body slots.

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 (Ø50mm)
| Pressure | Force (both ways) |
|---|---|
| 0.5 MPa | 881 N |
| 0.7 MPa | 1234 N |
| Max (@1.0 MPa) | 180 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 ACED50X20SB Is Used
Press-stamping fixture
The 881.2 N through-rod clamps aluminium brackets in a stamping jig, and the rear rod carries a CMSE switch flag to confirm full clamp before the press cycle starts.
Bidirectional pusher on a packaging line
Equal force both ways makes the ACED50X20SB ideal for a carton pusher that must eject and return with the same 1233.7 N at 0.7 MPa, at conveyor speeds inside the 30-500 mm/s band.
Slide table on a CNC tending cell
The double rod resists rotation on a short-stroke slide positioning machined parts, and the compact body fits where an ISO 15552 profile cylinder would overhang the frame.
Is the Airtac ACED Double-acting Compact Cylinder ACED50X20SB the Right Cylinder?
At 50 mm bore you sit mid-range: the 40 mm ACED gives 571.8 N at 0.5 MPa if your clamp load is lighter, while the 63 mm bore steps up to 1458.1 N for heavier tooling. Keep in mind the piston drifts when air is lost, so add a rod lock or pilot check if the load must stay put. FA/FB flange, LB foot and FTC brackets bolt to the ISO 21287 face, and I/Y rod knuckles suit the male threaded ends. Strokes to 250 mm are standard for this bore; 20 mm is a stock length.
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 ACED50X20SB FAQ
Yes. Because a rod exits both covers, both strokes use the rod-side area: 881.2 N at 0.5 MPa and 1233.7 N at 0.7 MPa, equal extend and retract. At the full 1.0 MPa rating the bore reaches about 179.7 kgf. Operating range is 0.15-1.0 MPa (22-145 psi) with 1.5 MPa (215 psi) proof pressure, and speed spans 30-500 mm/s.
It is an ISO 21287 compact cylinder with a hard-anodized aluminium body and S45C hard-chrome plated 16 mm rods, about 50% shorter in mounting length than an ISO 15552 profile cylinder. A fixed TPU bumper at each cover absorbs end-of-stroke energy. The 1/8" PT ports serve the 50 mm bore, the male threaded rod ends take I/Y knuckles, and this model carries the optional -S magnet so CMSE / DMSE switches can be clipped to the body slots.
