About the Airtac ACED Double-acting Compact Cylinder ACED40X55SB
The ACED40X55SB is a double acting, double-rod compact cylinder built to ISO 21287: a 40 mm bore with a 55 mm stroke and a 12 mm rod leaving both covers, so thrust is identical on the out-stroke and the return (571.8 N at 0.5 MPa, 800.5 N at 0.7 MPa on either side). The male rod thread from the B code bolts straight to your tooling, and the short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, which is why it slots into tight machine frames and guarding where a full-length body simply will not fit.
Because the through-rod exits both ends, the back-side rod can carry a sensor flag or a second fixture while the front rod does the work, and the symmetric mount resists rotation and light side load. This model carries the optional -S magnet, so CMSE or DMSE reed and solid-state switches can be clipped onto the body slots for end-of-stroke signalling. Plan real work at roughly 343 N (about 35 kg of push) rather than the full 571.8 N rating, and expect about 29 kg of vertical lift at a 2:1 margin. Operating range is 0.15-1.0 MPa (22-145 psi) with a 1.5 MPa (215 psi) proof pressure, speed 30-500 mm/s, and a fixed TPU bumper 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 (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 ACED40X55SB Is Used
Push-pull press fixture
The equal 571.8 N thrust in both directions suits a small stamping or marking jig that clamps on the out-stroke and retracts the tool with the same force, with the male rod thread taking a custom punch nose.
Bidirectional conveyor stopper
A rod on each cover lets one cylinder raise and lower a stop blade or divert a carton on a packaging line, with the fitted -S magnet and a CMSE switch confirming blade position at each end.
Test rig reciprocating slide
The through-rod drives a sample carriage back and forth at 30-500 mm/s on a laboratory fatigue rig, the rear rod carrying a position flag while the symmetric mount keeps the slide tracking true.
Is the Airtac ACED Double-acting Compact Cylinder ACED40X55SB 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 - choose it when a 32 mm is marginal and a 50 mm is oversized. The 55 mm stroke is well inside the 200 mm maximum standard stroke for this bore, so it ships as a catalogue item. FA/FB flanges, LB feet and FTC brackets plus I/Y rod knuckles bolt to the ISO 21287 face, and the fitted -S magnet means CMSE/DMSE switches work out of the box. Note that a plain double-rod cylinder drifts when air is lost - add a rod lock or pilot check if the load must be held.
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 ACED40X55SB FAQ
Yes - the double-rod design exposes the rod-side area on both strokes, so output is equal each way: 571.8 N at 0.5 MPa and 800.5 N at 0.7 MPa, with a maximum of about 116.6 kgf at 1.0 MPa. Operating pressure is 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), and speed range 30-500 mm/s. For sizing, treat roughly 343 N (about 35 kg) as the practical working force, or about 29 kg of vertical lift at a 2:1 margin.
The ISO 21287 short body cuts mounting length by about 50% versus an ISO 15552 profile cylinder, so it fits shallow machine envelopes, and a fixed TPU bumper at each end absorbs end-of-stroke shock. The S code means this unit carries the optional -S magnet, so CMSE or DMSE reed or solid-state switches can be mounted in the body slots for position feedback. Ports are 1/8" (PT), the rod end is male thread, and FA/FB, LB and FTC mountings plus I/Y knuckles attach to the standard ISO 21287 face.
