Airtac ACED Double-acting Compact Cylinder ACED40X45B
The AirTAC Airtac ACED Double-acting Compact Cylinder ACED40X45B is a genuine double acting, double rod ISO 21287 compact air cylinder with a Ø40mm bore and 45mm 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 ACED40X45B
A double acting compact actuator built to ISO 21287, the ACED40X45B pushes a 12 mm piston rod out of BOTH covers, so thrust is identical on the extend and retract strokes. At the bore 40 rating that is 571.8 N at 0.5 MPa and 800.5 N at 0.7 MPa in either direction, with a peak of 116.6 kgf at 1.0 MPa. The male rod thread (B code) on each end bolts straight to your tooling.
The short hard-anodized aluminium body saves about 50% of the mounting length of an ISO 15552 profile cylinder, which is why it slots into tight machine frames and slide assemblies. A fixed TPU bumper at each end absorbs end-of-stroke shock, the S45C hard-chrome rod resists wear, and the through-rod resists rotation so the back-end rod can carry a sensor flag. Plan on roughly 343 N of usable work at 0.5 MPa, which lifts about 29 kg vertically with a 2:1 margin. Speed range is 30-500 mm/s over 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 (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 ACED40X45B Is Used
Reciprocating slide on a packaging machine
The double rod gives equal 571.8 N thrust on extend and retract at 0.5 MPa, ideal for a pusher slide that must return a tray carrier with the same force it pushed it out.
Symmetric clamp fixture for CNC loading
A rod on each cover lets one cylinder clamp a 29 kg aluminium blank from either side of a jig, with the male M8x1.25 rod threads taking standard knuckle joints.
Sensor flag carrier on a test rig
The back-end rod carries a flag past a switch to log stroke position, while the 45 mm stroke cycles at up to 500 mm/s between fixed TPU bumpers.
Is the Airtac ACED Double-acting Compact Cylinder ACED40X45B the Right Cylinder?
At 571.8 N per side, bore 40 sits between the 50 mm bore (881.2 N) and the 32 mm bore (345.6 N) in the ACED family, so step up or down if your force budget shifts. Remember the piston will drift if air is lost, so add a rod lock or pilot check for a held load. FA/FB flanges, LB feet and FTC brackets mount on the ISO 21287 face; this unit has no magnet, so order the -S code instead if you need CMSE or DMSE switch position feedback.
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 ACED40X45B FAQ
Yes, identical both ways because a rod exits each cover and both strokes use the rod-side area: 571.8 N at 0.5 MPa, 800.5 N at 0.7 MPa, and up to 116.6 kgf at the 1.0 MPa maximum. Operating pressure is 0.15-1.0 MPa (22-145 psi) with a 1.5 MPa (215 psi) proof rating, and air must be filtered to 40 um.
The ISO 21287 body is about 50% shorter in mounting length than an ISO 15552 profile cylinder, so it fits shallow gantries and guard spaces. The B code means male rod threads on both 12 mm rods; the 1/8" PT ports suit bores 32-63. This unit has no magnet, so order the -S variant if you want CMSE or DMSE switches, and note the fixed TPU bumpers only decelerate the piston, they never hold a load.
