Airtac ACED Double-acting Compact Cylinder ACED25X70SB
The AirTAC Airtac ACED Double-acting Compact Cylinder ACED25X70SB is a genuine double acting, double rod ISO 21287 compact air cylinder with a Ø25mm bore and 70mm stroke, M5×0.8 air ports and a hard-anodized aluminium body.

About the Airtac ACED Double-acting Compact Cylinder ACED25X70SB
A double acting compact cylinder built to ISO 21287, the ACED25X70SB carries a 25 mm bore with a 70 mm stroke and a rod leaving BOTH covers. Because each side works on the rod-side area, output is a symmetric 206.2 N at 0.5 MPa and 288.6 N at 0.7 MPa in either direction. The male-threaded rod end (B code) bolts straight to external tooling, and the fitted -S magnet lets CMSE or DMSE switches report position along the body slots.
The short ISO 21287 body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight fixtures and guarding. For sizing, treat roughly 124 N (about 12.6 kg equivalent) as the practical working thrust at 0.5 MPa instead of the full rating. A hard-anodized aluminium body, S45C hard-chrome rod and fixed TPU bumpers at both ends keep it running at 30-500 mm/s on 0.15-1.0 MPa (22-145 psi) filtered air.

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 (Ø25mm)
| Pressure | Force (both ways) |
|---|---|
| 0.5 MPa | 206 N |
| 0.7 MPa | 289 N |
| Max (@1.0 MPa) | 42 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 ACED25X70SB Is Used
Pick-and-place on SMT feeder benches
The 206.2 N symmetric thrust and male rod thread drive a gripper arm between two PCB transfer nests, while the fitted magnet and a DMSE switch confirm each 70 mm reach.
Vial tray indexing in a lab filler
Equal force in both directions pushes and retracts the tray shuttle at identical speed, and the compact body fits under the laminar-flow hood where a profile cylinder cannot.
Carton flap tuck on a case packer
The through-rod resists the side load of the flap guide, and the rear rod carries a sensor flag so the PLC verifies the tuck before taping starts.
Is the Airtac ACED Double-acting Compact Cylinder ACED25X70SB the Right Cylinder?
At 206.2 N per side this bore sits between the 20 mm frame (117.8 N at 0.5 MPa) and the 32 mm frame (345.6 N at 0.5 MPa), so step up to 32 mm if your tooling mass grows. The 70 mm stroke is well inside the 150 mm standard limit for bore 25, so no made-to-order build is needed. Remember the piston drifts when air is lost - add a rod lock or pilot check if the load must stay put. FA/FB flanges, LB feet and CA clevises mount on the ISO 21287 face; the -S magnet is already fitted on this version for CMSE / DMSE 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 ACED25X70SB FAQ
Yes - the double-rod design exposes the rod-side area on both strokes, so force is equal either way: 206.2 N at 0.5 MPa and 288.6 N at 0.7 MPa, with a maximum of 42.0 kgf at 1.0 MPa. Operating range is 0.15-1.0 MPa (22-145 psi) on air filtered to 40 um, speed 30-500 mm/s, temperature -20 to +70 C.
The ISO 21287 short body cuts roughly 50% of the mounting length of an ISO 15552 profile cylinder, freeing space in tight gantries. This model carries the optional -S magnet, so CMSE or DMSE reed or solid-state switches clamp into the body slots for end-of-stroke or mid-stroke signals. A fixed TPU bumper at each end absorbs stroke-end impact, and FA/FB flange, LB foot or CA clevis brackets bolt directly to the standard mounting face.
