Airtac ACED Double-acting Compact Cylinder ACED50X40S
The AirTAC Airtac ACED Double-acting Compact Cylinder ACED50X40S is a genuine double acting, double rod ISO 21287 compact air cylinder with a Ø50mm bore and 40mm 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 ACED50X40S
A double acting compact cylinder built to ISO 21287, the ACED50X40S pushes a 16 mm rod out of BOTH covers, so thrust is identical on each stroke: 881.2 N at 0.5 MPa and 1233.7 N at 0.7 MPa. Because the through-rod is guided at both ends, it resists rotation and light side load, and the rear rod can carry a sensor flag or a second tooling plate. The -S code on this model means the magnet is already fitted, so CMSE or DMSE reed and solid-state switches mount directly in the body slots.
The short ISO 21287 body saves about 50% of the mounting length of an ISO 15552 profile cylinder, which matters inside tight jigs and guarding. The hard-anodized aluminium barrel carries a roller-burnished bore, the S45C rod is hard-chrome plated, and a fixed TPU bumper at each end absorbs end-of-stroke shock. At 0.5 MPa the rod-side area supports roughly 528 N of continuous work (about 54 kg), and with a 2:1 margin the rod will lift about 45 kg vertically - enough for a loaded palletizing fixture or a small die cart. Speed range is 30-500 mm/s across 0.15-1.0 MPa (22-145 psi).

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 ACED50X40S Is Used
Symmetric press fixture
The equal 881.2 N output on both strokes lets one ACED50X40S load and eject a workpiece in a machining jig without recalibrating for direction.
Gantry Z-axis with flag rod
The rear 16 mm rod carries a sensor flag for the fitted magnet, giving CMSE switch position feedback on a pick-and-place gantry in a 40 mm stroke.
Belt-line pusher station
A through-rod pusher on a packaging conveyor rejects cartons in either direction, with the TPU bumpers absorbing the stop at each end of the short stroke.
Is the Airtac ACED Double-acting Compact Cylinder ACED50X40S the Right Cylinder?
At 50 mm bore this sits mid-range: the 40 mm bore delivers 571.8 N at 0.5 MPa if your load is lighter, while the 63 mm bore reaches 1458.1 N for heavier clamping. Both strokes here see the same 881.2 N because the double rod exposes the rod-side area on each end. Remember that a plain double-rod cylinder drifts when air is lost - add a rod lock or pilot check valve if the load must stay put. FA/FB flanges, LB feet and FTC brackets bolt straight to the ISO 21287 face, and I or Y rod knuckles suit the 16 mm rod. Standard strokes for this bore run to 250 mm, so 40 mm is well inside range; the 1/8" port takes PT or G on request.
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 ACED50X40S FAQ
Yes - the double-rod design puts a 16 mm rod through both covers, so both strokes work on 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 rating at 1.0 MPa is 179.7 kgf. Operating pressure is 0.15-1.0 MPa (22-145 psi) with a 1.5 MPa (215 psi) proof pressure, and speed runs 30-500 mm/s.
The ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it fits shallow fixtures. This -S model carries the optional magnet, so CMSE or DMSE switches can be clamped into the body slots for end-position sensing. FA/FB flanges, LB feet and FTC brackets mount on the standard face, and the fixed TPU bumpers at both ends decelerate the piston - they do not hold or brake a load.
