Airtac ACED Double-acting Compact Cylinder ACED50X55B
The AirTAC Airtac ACED Double-acting Compact Cylinder ACED50X55B is a genuine double acting, double rod ISO 21287 compact air cylinder with a Ø50mm bore and 55mm 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 ACED50X55B
A double acting compact cylinder built to ISO 21287, the ACED50X55B pushes a 16 mm rod out of BOTH covers, so its 50 mm bore delivers the same 881.2 N at 0.5 MPa (1233.7 N at 0.7 MPa) on every stroke - no push/pull imbalance to design around. The male rod thread (B code) bolts straight to tooling, and the through-rod resists rotation and side load while the free back-end rod can carry a sensor flag or a second fixture.
The hard-anodized aluminium body with an S45C hard-chrome plated rod runs on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi), 30-500 mm/s, from -20 to 70 C. Its short ISO 21287 body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight gantries and guarding. Fixed TPU bumpers absorb end-of-stroke shock at both covers.

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 ACED50X55B Is Used
Bidirectional push-pull transfer
On a packaging line indexing trays between two lanes, the equal 881.2 N output in both directions lets one cylinder push the tray out and retract the pusher with identical force - no derating on the return stroke.
Symmetric press or stamp nest
A small electronics press stamping connector housings uses the male-threaded 16 mm rod on both ends: the front rod carries the punch, the back rod drives an ejector, both rated at 1233.7 N at 0.7 MPa.
Gantry Z-axis with flag rod
In a vision-inspection gantry with tight headroom, the short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, and the rear rod carries a flag for a proximity sensor to confirm full retract.
Is the Airtac ACED Double-acting Compact Cylinder ACED50X55B the Right Cylinder?
At 881.2 N per direction, the 50 mm bore sits between the 40 mm (571.8 N) and 63 mm (1458.1 N) options at 0.5 MPa - step down for lighter pick-and-place, step up for heavier clamping. The 55 mm stroke is well inside the 250 mm maximum standard stroke for this bore, so it ships as a standard build. 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. Mounting brackets (FA/FB flange, LB foot, FTC, I/Y knuckles) bolt to the ISO 21287 face. This unit has no magnet - 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 ACED50X55B FAQ
Yes - because a rod exits both covers, both strokes use the rod-side area of the 50 mm bore. Output is 881.2 N at 0.5 MPa and 1233.7 N at 0.7 MPa in EITHER direction, with a maximum of 179.7 kgf at 1.0 MPa. Operating pressure is 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), speed 30-500 mm/s, air filtered to 40 um, -20 to 70 C.
It is an ISO 21287 compact cylinder: hard-anodized aluminium body, S45C hard-chrome plated 16 mm rod through both covers, threaded aluminium covers, 1/8" PT ports and a fixed TPU bumper at each end that absorbs end-of-stroke energy. This version has no magnet; order the -S code to enable CMSE or DMSE switches. FA/FB flange, LB foot, FTC and I/Y knuckle hardware mounts on the standard ISO 21287 face.
