Airtac ACED Double-acting Compact Cylinder ACED50X125SB
The AirTAC Airtac ACED Double-acting Compact Cylinder ACED50X125SB 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 ACED50X125SB
The ACED50X125SB is a double acting, double-rod compact cylinder built to ISO 21287: a 50 mm bore with a 16 mm rod exiting both covers, so thrust is identical on the extend and return stroke - 881.2 N at 0.5 MPa and 1233.7 N at 0.7 MPa either way. The male rod thread (B code) suits external nuts and knuckles, and the 1/8" PT port feeds air filtered to 40 um across a 0.15-1.0 MPa (22-145 psi) operating band.
The short ISO 21287 body saves about 50% of the mounting length of an ISO 15552 profile cylinder, which is why this 125 mm stroke unit slots into tight clamping stations and sliding guards. Because the magnet is the -S option and this model carries it, CMSE or DMSE switches read position directly on the body slots. A fixed TPU bumper at each end absorbs end-of-stroke shock, and speed runs 30-500 mm/s from -20 to +70 C.

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 ACED50X125SB Is Used
Press-fit clamping of aluminium housings
The symmetric 881.2 N push and pull lets one ACED50X125SB both seat and eject a housing in a machining-centre fixture, with the 125 mm stroke clearing the loader arm.
Sliding guard doors on CNC cells
The short ISO 21287 body fits behind narrow guard frames, and the fitted -S magnet feeds CMSE switch signals to the interlock relay at both door positions.
Reciprocating transfer beams on packaging lines
A rod at each cover anchors the beam symmetrically, the through-rod resists rotation at 30-500 mm/s, and the rear rod carries a DMSE flag for stroke counting.
Is the Airtac ACED Double-acting Compact Cylinder ACED50X125SB the Right Cylinder?
At 881.2 N per direction, the 50 mm bore sits between the 40 mm class (571.8 N at 0.5 MPa) and the 63 mm class (1458.1 N at 0.5 MPa) - step down for lighter clamps, up for heavier presses. The 125 mm stroke is comfortably inside the 250 mm standard limit for this bore. Remember the piston drifts if air is lost; add a rod lock or pilot check valve where a load must stay put. FA/FB flanges, LB feet and FTC brackets bolt to the ISO 21287 face, and I or Y rod knuckles suit the male thread.
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 ACED50X125SB FAQ
Yes - the double-rod design exposes the rod-side area on both strokes, so output 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 range is 0.15-1.0 MPa (22-145 psi) with 1.5 MPa (215 psi) proof pressure.
It is an ISO 21287 compact cylinder whose hard-anodized aluminium body saves about 50% of the mounting length of an ISO 15552 profile cylinder. The 16 mm rod exits both covers with a male thread, fixed TPU bumpers absorb end-of-stroke energy, and FA/FB flange, LB foot and FTC brackets mount on the standard face. The -S magnet on this model accepts CMSE / DMSE switches; without ordering -S there is no magnet.
