Airtac ACED Double-acting Compact Cylinder ACED40X120
The AirTAC Airtac ACED Double-acting Compact Cylinder ACED40X120 is a genuine double acting, double rod ISO 21287 compact air cylinder with a Ø40mm bore and 120mm stroke, 1/8" air ports and a hard-anodized aluminium body.

About the Airtac ACED Double-acting Compact Cylinder ACED40X120
The ACED40X120 is a double acting AirTAC compact cylinder built to ISO 21287, with a piston rod leaving BOTH covers. Because each stroke works on the rod-side area, output force is equal in both directions: 571.8 N at 0.5 MPa and 800.5 N at 0.7 MPa, either way. The through-rod resists rotation and side load, gives a symmetric mounting face, and the rear rod can carry a sensor flag on automated tooling.
The short ISO 21287 body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so this 120 mm stroke unit fits tight guarding and gantry frames. A fixed TPU bumper at each end absorbs end-of-stroke shock, the hard-anodized aluminium body runs on an S45C hard-chrome rod, and speed spans 30-500 mm/s. For sizing, expect roughly 343 N (about 35 kg) of usable push at 0.5 MPa, or a vertical lift of about 29 kg 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 ACED40X120 Is Used
Gantry pick-and-place
The through-rod carries a Z-axis tooling plate on both ends while the 571.8 N symmetric force keeps acceleration identical up and down inside a low-profile gantry frame.
Press-fit staking station
Equal 800.5 N force at 0.7 MPa in both directions suits a benchtop staking jig that must retract a part off the punch as positively as it pressed it.
Bidirectional conveyor pusher
A rear rod on the back cover drives a flag for CMSE / DMSE sensing (with the -S magnet ordered) while the front rod pushes cartons across a transfer conveyor.
Is the Airtac ACED Double-acting Compact Cylinder ACED40X120 the Right Cylinder?
At 571.8 N per direction, bore 40 sits between bore 32 (345.6 N) and bore 50 (881.2 N) at 0.5 MPa - step down for lighter pick-and-place, step up for heavier clamping. The 120 mm stroke is within the 200 mm standard range for this bore, so no made-to-order build is needed. Remember the piston drifts if air is lost; add a rod lock or pilot check valve where a load must stay put. This version has a female M8x1.25 rod thread and PT ports; FA/FB flange, LB foot or FTC brackets bolt to the ISO 21287 face. There is no magnet fitted - order the -S code if you need CMSE / DMSE switch position sensing.
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 ACED40X120 FAQ
Yes - the double-rod design exposes the rod-side area on both strokes, so force is equal either way: 571.8 N at 0.5 MPa and 800.5 N at 0.7 MPa (22-145 psi working range, 1.5 MPa / 215 psi proof). Maximum force at 1.0 MPa is 116.6 kgf. Speed range is 30-500 mm/s on filtered air.
The ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, with a fixed TPU bumper at each end and FA/FB flange, LB foot or FTC mounting. Position sensing needs the optional -S magnet code - this model (no S) has no magnet, so order ACED40X120S to run CMSE or DMSE switches.
