This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACED25X50S, the same code under the new prefix. The ACE replacement is a current-production ISO 21287 compact cylinder in the same bore, stroke and force class, with a matching short body and the same mounting-accessory family, so it fits the same envelope. Confirm mounting-interface dimensions against the ACE datasheet before ordering.
Airtac ACPD Double Rod Compact Cylinder ACPD25X50S
The AirTAC ACPD Double Rod Compact Cylinder ACPD25X50S is a double acting, double rod DIN-standard tight/compact air cylinder with a Ø25mm bore and 50mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACED25X50S (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPD Double Rod Compact Cylinder ACPD25X50S
Double acting with a rod leaving both covers, the ACPD25X50S pushes and pulls with identical force because each stroke works on the rod-side area: 206.2 N at 0.5 MPa and 288.6 N at 0.7 MPa in either direction. The 25 mm bore drives a 10 mm through-rod over a 50 mm stroke at 30-500 mm/s, with a fixed TPU bumper at each end and M5x0.8 ports on a hard-anodized aluminium body. The S code on this model means the optional -S magnet is fitted, so CMSE or DMSE reed and solid-state switches can be clipped on for end-of-stroke signalling.
The short ISO 21287-class body saves about 50% of the mounting length of an ISO 15552 profile cylinder, which is why it suits tight jigs and guard-mounted tooling. Because the through-rod resists rotation and light side load, the rear rod can also carry a sensor flag on a gating station. Note that this model is discontinued: the current-production direct is the ACED25X50, so confirm the ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACED25X50S (ISO 21287) carries the same bore/stroke/force class; confirm mounting-interface dimensions against the ACE datasheet before installation. Rod type: female thread (blank) or male thread (B). Thread options: PT (blank) / G.
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 ACPD Double Rod Compact Cylinder ACPD25X50S Is Used
Symmetric push-pull gating
A packaging line gate that must clamp and retract with the same 206.2 N force at 0.5 MPa uses the through-rod on both covers, keeping the mechanism balanced without recalibrating for direction.
Position-flagged test fixture
On an electronics test bench, the rear rod of the 25 mm through-rod carries a sensor flag while the -S magnet drives CMSE or DMSE switches for end-of-stroke confirmation over the 50 mm stroke.
Compact press-fit station
A small assembly cell pressing bushings into housings gets about 123 N of usable working force at 0.5 MPa, and the short body fits where an ISO 15552 profile cylinder would be roughly twice as long.
Replacing the Airtac ACPD Double Rod Compact Cylinder ACPD25X50S with the ACED25X50S
Size around the load: at 0.5 MPa the 25 mm bore gives 206.2 N both ways, so keep real working demand near 123 N. If your fixture needs more, step up to the 32 mm bore at 345.6 N; if less, the 20 mm bore at 117.8 N may be enough. A plain double-rod cylinder drifts when air is lost, so add a rod lock or pilot check if the load must stay put. FA/FB flange and LB foot mountings bolt to the standard face, and the -S magnet on this model pairs with CMSE / DMSE switches. For new builds, order the ACED25X50 instead - same bore, stroke and force class, currently in production.
Replacement checklist
- ✓ Current-production ACE → ACED25X50S
- ✓ Same bore / stroke / force class
- ✓ Confirm ISO 21287 mounting dimensions
- ✓ Port/thread type (PT / G)
- ✓ Add -S for magnet if you need sensors
Airtac ACPD Double Rod Compact Cylinder ACPD25X50S FAQ
Because a rod exits both covers, force is equal in both directions: 206.2 N at 0.5 MPa and 288.6 N at 0.7 MPa on every stroke, with a maximum of 42.0 kgf at 1.0 MPa. Operating range is 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), speed 30-500 mm/s, and the M5x0.8 ports take air filtered to 40 um.
No - the ACPD family is discontinued. The current-production direct is the ACED25X50, made by swapping the P for an E: same 25 mm bore, 50 mm stroke and force class in the ISO 21287 short-body format. Since the ACP was built to a DIN standard, confirm the ISO 21287 mounting dimensions before swapping. The fixed TPU bumpers, M6x1.0 female rod thread and optional -S magnet for CMSE / DMSE switches carry over in concept.
