This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACED25X125S, 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 ACPD25X125S
The AirTAC ACPD Double Rod Compact Cylinder ACPD25X125S is a double acting, double rod DIN-standard tight/compact air cylinder with a Ø25mm bore and 125mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACED25X125S (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPD Double Rod Compact Cylinder ACPD25X125S
Double acting with a rod leaving both covers, the ACPD25X125S pushes and pulls with identical output 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 125 mm stroke at 30-500 mm/s, with a fixed TPU bumper at each end and a female M6x1.0 rod thread. Air supply is 0.15-1.0 MPa (22-145 psi), filtered to 40 um, with a 1.5 MPa (215 psi) proof rating and -20 to +70 C operation.
The short ISO 21287-class body cuts roughly 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight fixtures and guarding. The -S code on this model means the magnet is fitted, so CMSE or DMSE reed and solid-state switches can be clipped on for end-of-stroke signalling. Note that the ACPD family is discontinued: the current-production direct is ACED25X125, so confirm ISO 21287 mounting dimensions before ordering.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACED25X125S (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 ACPD25X125S Is Used
Reciprocating test rigs
The symmetric through-rod drives a fixture back and forth on an electronics test bench, delivering 206.2 N in each direction so the return stroke needs no derating.
Position-flagged assembly stations
With the -S magnet fitted, CMSE or DMSE switches confirm both end positions on a small-parts pressing station, while the rear rod carries a secondary flag for PLC interlocks.
Replacing the Airtac ACPD Double Rod Compact Cylinder ACPD25X125S with the ACED25X125S
At 206.2 N per side at 0.5 MPa, this bore sits between the 20 mm (117.8 N) and 32 mm (345.6 N) double-rod units, so step up to 32 mm if your tooling weight climbs or drop to 20 mm for lighter pick-and-place heads. The 125 mm stroke is within the 150 mm standard range for bore 25, so no made-to-order surcharge applies. The through-rod resists rotation and side load and lets you hang a sensor flag off the rear rod; the fitted -S magnet pairs with CMSE / DMSE switches. Remember the piston drifts if air is lost, so add a rod lock or pilot check for held loads. For new designs, order ACED25X125 instead - same bore, stroke and force class.
Replacement checklist
- ✓ Current-production ACE → ACED25X125S
- ✓ 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 ACPD25X125S FAQ
Yes. Because a rod exits both covers, both strokes use the rod-side area: 206.2 N at 0.5 MPa and 288.6 N at 0.7 MPa, equal push and pull. At 1.0 MPa the bore reaches a maximum of 42.0 kgf.
The -S code on this model means the magnet is fitted, so CMSE reed or DMSE solid-state switches mount directly on the body for end-of-stroke detection. The ACPD family is discontinued; the current-production successor is ACED25X125 (swap the P for an E), which matches the same bore, stroke and force class - confirm the ISO 21287 mounting dimensions before swapping, since the ACP is DIN-standard.
