Airtac ACED Double-acting Compact Cylinder ACED25X50SB
The AirTAC Airtac ACED Double-acting Compact Cylinder ACED25X50SB is a genuine double acting, double rod ISO 21287 compact air cylinder with a Ø25mm bore and 50mm stroke, M5×0.8 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 ACED25X50SB
A double acting compact cylinder built to ISO 21287, the ACED25X50SB pushes a 25 mm bore through a 50 mm stroke with a rod leaving both covers, so output force is equal in both directions - 206.2 N at 0.5 MPa and 288.6 N at 0.7 MPa on either stroke. The male rod thread (B code) suits external nuts and clevis-style tooling, and the through-rod resists rotation while the rear rod can carry a sensor flag. Speed range is 30-500 mm/s over 0.15-1.0 MPa (22-145 psi) of clean, 40 um filtered air.
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 jigs and guarding where a full-length body will not fit. The hard-anodized aluminium barrel pairs with an S45C hard-chrome rod, and fixed TPU bumpers absorb end-of-stroke shock at both covers. This model carries the optional -S magnet, so CMSE / DMSE switches can be clamped onto the body slots for position feedback. For sizing: the 206.2 N rating translates to roughly 21 kgf, so plan on lifting about 10 kg vertically with a 2:1 margin.

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 ACED25X50SB Is Used
Symmetric jig clamping
The equal 206.2 N force in both directions lets one cylinder clamp and release a machined housing in a drilling fixture with identical grip either way.
Balanced slide actuation
A rod on each cover drives a conveyor gate or shuttle table symmetrically, and the through-rod resists the rotation a single-rod layout would introduce.
Position-verified ejector
With the fitted -S magnet and a DMSE switch, a packaging machine confirms full advance and retract of a 50 mm reject pusher at up to 500 mm/s.
Is the Airtac ACED Double-acting Compact Cylinder ACED25X50SB the Right Cylinder?
At 206.2 N per side, this 25 mm bore sits between the 20 mm (117.8 N at 0.5 MPa) and the 32 mm (345.6 N at 0.5 MPa) - step down for lighter pick-and-place arms, step up for heavier clamping. The 50 mm stroke is well inside the 150 mm standard limit for this bore. Remember the piston drifts if air is lost, so add a rod lock or pilot check for held loads. FA/FB flanges, LB feet, CA clevis and FTC brackets bolt straight to the ISO 21287 face, and the -S magnet on this unit pairs with CMSE / DMSE switches.
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 ACED25X50SB FAQ
Yes - the double-rod design means both strokes use the rod-side area, so output is equal both ways: 206.2 N at 0.5 MPa, 288.6 N at 0.7 MPa, and a maximum of 42.0 kgf at 1.0 MPa. Operating range is 0.15-1.0 MPa (22-145 psi) with a 1.5 MPa (215 psi) proof pressure, running on air filtered to 40 um at 30-500 mm/s and -20 to +70 C.
The ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it fits shallow gantries and guarded stations. Fixed TPU bumpers at both covers absorb end-of-stroke shock. This unit includes the optional -S magnet for CMSE / DMSE switches, and FA/FB flange, LB foot, CA clevis or FTC brackets mount directly on the standard face.
