Airtac ACED Double-acting Compact Cylinder ACED50X55SB
The AirTAC Airtac ACED Double-acting Compact Cylinder ACED50X55SB 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 ACED50X55SB
A double acting compact cylinder built to ISO 21287, the ACED50X55SB pushes a 16 mm rod out of BOTH covers, so thrust is identical on the extend and retract strokes: 881.2 N at 0.5 MPa and 1233.7 N at 0.7 MPa. The male rod thread (B code) bolts straight to your tooling, and the through-rod resists rotation and side load while the free back-end rod can carry a sensor flag or a symmetric counter-mount.
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 pick-and-place gantries and press fixtures. A fixed TPU bumper absorbs end-of-stroke shock at both ends, the hard-anodized aluminium body runs on a hard-chrome S45C rod, and the fitted -S magnet accepts CMSE / DMSE switches for stroke-position feedback.

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 ACED50X55SB Is Used
Fixture clamping on CNC machining centers
Equal 881.2 N clamp and release force in both directions lets one ACED50X55SB swing a jig gate open and lock it closed with the same margin, and the male rod thread takes a custom clamp arm directly.
Position feedback on a packaging machine pusher
The fitted -S magnet drives CMSE / DMSE switches at both ends of the 55 mm stroke, confirming carton push and home positions on a 1/8" PT air supply at 30-500 mm/s.
Is the Airtac ACED Double-acting Compact Cylinder ACED50X55SB the Right Cylinder?
For this 50 mm bore the through-rod delivers 881.2 N in each direction at 0.5 MPa, so size the load to about 529 N of real work. If your part weighs less, a 40 mm ACED gives 571.8 N both ways; if you need more, step up to the 63 mm bore at 1458.1 N. Stroke 55 mm sits well inside the 250 mm standard range for bore 50, so no made-to-order build is needed. Remember the piston drifts if air is lost - add a rod lock or pilot check where a load must be held. FA/FB flanges, LB feet and FTC brackets mount on the ISO 21287 face, and the fitted magnet works with CMSE / DMSE switches. Ports are 1/8" PT.
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 ACED50X55SB FAQ
Yes - the double-rod design exposes the rod-side area on both strokes, so force is equal extending and retracting: 881.2 N at 0.5 MPa, 1233.7 N at 0.7 MPa, 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, and the 55 mm stroke is within the 250 mm standard range for the 50 mm bore.
The ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it fits where a full-length cylinder cannot. This model carries the optional -S magnet, so CMSE / DMSE reed or solid-state switches clamp into the body slots for end-of-stroke or mid-stroke sensing. A fixed TPU bumper at each end absorbs impact, and FA/FB flange, LB foot or FTC brackets bolt to the standard mounting face.
