Airtac ACED Double-acting Compact Cylinder ACED40X50S
The AirTAC Airtac ACED Double-acting Compact Cylinder ACED40X50S is a genuine double acting, double rod ISO 21287 compact air cylinder with a Ø40mm bore and 50mm stroke, 1/8" air ports and a hard-anodized aluminium body.

About the Airtac ACED Double-acting Compact Cylinder ACED40X50S
A double acting compact cylinder built to ISO 21287, the ACED40X50S pushes a 12 mm hard-chromed S45C rod out of BOTH covers, so thrust is identical on the extend and return strokes: 571.8 N at 0.5 MPa and 800.5 N at 0.7 MPa. The 40 mm bore runs on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi), with speed control from 30 to 500 mm/s and a fixed TPU bumper at each end to soften the stroke ends.
The short ISO 21287 body saves about 50% of the mounting length of an ISO 15552 profile cylinder, which is why it slots into tight guarding and slide fixtures. This -S version carries the optional magnet, so CMSE or DMSE reed or solid-state switches can be clipped onto the body slots for end-of-stroke sensing. In practice, plan on roughly 343 N of usable push at 0.5 MPa (about 35 kgf), which lifts roughly 29 kg vertically 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 (Ø40mm)
| Pressure | Force (both ways) |
|---|---|
| 0.5 MPa | 572 N |
| 0.7 MPa | 800 N |
| Max (@1.0 MPa) | 117 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 ACED40X50S Is Used
Symmetric clamp fixtures
The 571.8 N equal thrust on both rods clamps a machined housing from two sides on a CNC fixture, with the 50 mm stroke clearing part load and unload.
Pusher on packaging lines
A 40 mm double-rod body pushes cartons sideways off a conveyor at up to 500 mm/s, and the rear rod carries a flag past a DMSE switch for position feedback.
Reciprocating slide drive
Driving a light linear slide, the through-rod resists rotation so the carriage stays square, with the TPU bumpers absorbing the 50 mm stroke ends.
Is the Airtac ACED Double-acting Compact Cylinder ACED40X50S the Right Cylinder?
At 571.8 N per direction, the 40 mm bore sits between the 32 mm (345.6 N) and 50 mm (881.2 N) classes at 0.5 MPa - step down for lighter clamping, up for heavier press-fit work. The through-rod resists rotation and side load and gives a symmetric mount, and the back-end rod can carry a sensor flag. Note that a plain double-rod cylinder drifts when air is lost; add a rod lock or pilot check if the load must stay put. FA/FB flange, LB foot and FTC brackets plus I/Y rod knuckles bolt straight to the ISO 21287 face, and the female M8x1.25 rod thread accepts standard tooling. This unit already includes the -S magnet for 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 ACED40X50S FAQ
Because a rod exits both covers, force is equal in both directions: 571.8 N at 0.5 MPa and 800.5 N at 0.7 MPa on the extend and return alike. At 1.0 MPa the rod-side area reaches 116.6 kgf maximum. Operating range is 0.15-1.0 MPa (22-145 psi) with a 1.5 MPa (215 psi) proof pressure, on air filtered to 40 um.
The ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it fits shallow slides and guarded stations. This -S version carries the magnet, so CMSE or DMSE switches mount in the body slots for end-of-stroke signals. A fixed TPU bumper at each end decelerates the piston, and FA/FB flange or LB foot brackets bolt to the standard face. Outline dimensions: confirm from datasheet.
