Airtac ACED Double-acting Compact Cylinder ACED50X125B
The AirTAC Airtac ACED Double-acting Compact Cylinder ACED50X125B is a genuine double acting, double rod ISO 21287 compact air cylinder with a Ø50mm bore and 125mm 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 ACED50X125B
A double acting compact cylinder built to ISO 21287, the ACED50X125B pushes a 16 mm hard-chromed rod out of BOTH covers, so thrust is identical on every stroke: 881.2 N at 0.5 MPa and 1233.7 N at 0.7 MPa. Because the through-rod is guided at both ends, it shrugs off rotation and light side load, and the free back rod makes a handy mount for a sensor flag on gantry or pick-place tooling.
The short hard-anodized aluminium body saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, which is why it slots into tight jigs and guarding. A fixed TPU bumper at each end tames end-of-stroke shock, ports are 1/8", and the male rod thread (B code) bolts straight to your tooling. Add the optional -S magnet if you later want CMSE / DMSE switch sensing.

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 ACED50X125B Is Used
Reciprocating conveyor pushers
The symmetric 881.2 N thrust and through-rod guidance suit pusher arms that index cartons on packaging lines at 30-500 mm/s, with the back rod carrying a position flag.
Jig and fixture clamping
About 529 N of practical clamping force at 0.5 MPa holds aluminium machined parts in drilling and milling fixtures, and the short body fits inside tight jig plates.
Is the Airtac ACED Double-acting Compact Cylinder ACED50X125B the Right Cylinder?
At 881.2 N per direction, the 50 mm bore sits between the 40 mm (571.8 N) and the 63 mm (1458.1 N) in the ACED range; step down for lighter clamping, up when 881 N is marginal. The 125 mm stroke is well inside the 250 mm standard limit for this bore, so it ships as a catalogue item, not a made-to-order build. Mount with FA/FB flange, LB foot or FTC brackets and I/Y rod knuckles on the ISO 21287 face. Note that like any plain double-rod cylinder it will drift if air is lost - specify a rod lock or pilot check where a load must be held. Order the -S code only if position sensing is needed.
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 ACED50X125B FAQ
Yes - the double-rod design exposes the rod-side area on both strokes, so force is equal either way: 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 range 30-500 mm/s, and the 1/8" port serves both ends of the 50 mm bore.
The ISO 21287 short-body aluminium construction saves about 50% of the mounting length of an ISO 15552 profile cylinder, and a fixed TPU bumper at each end absorbs end-of-stroke shock - it decelerates only, it is not adjustable and never holds a load. Position sensing requires the optional -S magnet ordered with the cylinder; only then can CMSE or DMSE switches be mounted on the body slots.
