About the Airtac ACED Double-acting Compact Cylinder ACED50X120S
A double acting compact cylinder built to ISO 21287, the ACED50X120S pushes a 16 mm rod out of BOTH covers, so thrust is identical on every stroke: 881.2 N at 0.5 MPa and 1233.7 N at 0.7 MPa, whichever end you connect. The 120 mm stroke sits well inside the 250 mm standard range for a 50 mm bore, and the short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, letting it slide into tight guarding where a full-length body cannot.
The through-rod resists rotation and side load and gives a symmetric mount, so the rear rod can carry a sensor flag or a counter fixture while the front rod does the work. Because both strokes use the rod-side area, a practical working figure is roughly 529 N (about 54 kg of force) at 0.5 MPa, which lifts around 45 kg vertically with a 2:1 margin. The -S code on this model means the magnet is fitted, so CMSE or DMSE switches mount directly in the body slots. Air supply is 0.15-1.0 MPa (22-145 psi), speed 30-500 mm/s, and a fixed TPU bumper sits at each end.

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 ACED50X120S Is Used
Symmetric CNC fixture clamping
The equal 881.2 N thrust from both rod ends lets one cylinder clamp a machined aluminium housing from two sides in a milling fixture, keeping clamp pressure identical without tuning two separate actuators.
Packaging line pusher with position sensing
With the magnet fitted, a DMSE switch at each end confirms box present and retract complete on a carton transfer station, while the 120 mm stroke clears a 100 mm conveyor lane.
Battery assembly press assist
About 54 kg of usable force at 0.5 MPa seats battery modules into EV pack trays, and the rear rod carries a fixture plate so the operator loads parts while the front rod presses.
Is the Airtac ACED Double-acting Compact Cylinder ACED50X120S the Right Cylinder?
For a 50 mm bore, 881.2 N at 0.5 MPa both ways suits clamping, pressing and lift duties up to roughly 54 kg of usable force. Step down to the 40 mm bore (571.8 N at 0.5 MPa) for lighter tooling, or up to the 63 mm bore (1458.1 N at 0.5 MPa) when the part is heavier. The 120 mm stroke is a standard length for this bore, so no made-to-order build is needed. Note that the piston will drift if air is lost - add a rod lock or pilot check valve where the load must stay put. FA/FB flanges, LB feet and FTC brackets bolt straight to the ISO 21287 face, and the fitted magnet pairs with CMSE / DMSE switches.
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 ACED50X120S FAQ
Yes - the double-rod design puts a 16 mm rod through both covers, so every stroke uses the rod-side area. At 0.5 MPa you get 881.2 N, at 0.7 MPa you get 1233.7 N, and the maximum at 1.0 MPa is 179.7 kgf, identical whichever end is pressurized. Operating range is 0.15-1.0 MPa (22-145 psi) with 1.5 MPa (215 psi) proof pressure, speed 30-500 mm/s, and the 1/8" port is fixed by the 50 mm bore.
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 cells. The hard-anodized aluminium body carries a fixed TPU bumper at each end to soften end-of-stroke contact, and the -S code on this model means the magnet is fitted, so CMSE reed or DMSE solid-state switches clip into the body slots for end-position feedback. FA/FB flange, LB foot and FTC mounting brackets bolt directly to the standard face.
