This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACED25X15B, 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.

The AirTAC ACPD Double Rod Compact Cylinder ACPD25X15B is a double acting, double rod DIN-standard tight/compact air cylinder with a Ø25mm bore and 15mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACED25X15B (ISO 21287 ACE), in the same bore, stroke and force class.
Double acting with a rod leaving both covers, the ACPD25X15B pushes and pulls with the same 206.2 N at 0.5 MPa (288.6 N at 0.7 MPa) because both strokes work on the rod-side area. The 25 mm bore, 15 mm stroke and male rod thread (the B code) suit short symmetric clamping moves, and the through-rod on the far cover can carry a sensor flag or a second fixture. Speed range is 30-500 mm/s over 0.15-1.0 MPa (22-145 psi).
This discontinued DIN-standard compact cylinder is built around a hard-anodized aluminium body with an S45C hard-chrome rod and a fixed TPU bumper at each end. Its short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight jigs and guarding. For new projects order the current direct replacement ACED25X15 and confirm the ISO 21287 mounting dimensions.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACED25X15B (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.
| 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).
| ACPD | DIN compact cylinder (double-rod, discontinued). |
|---|---|
| 25 | Bore size in mm. |
| ×15 | Stroke length in mm. |
| S | Optional built-in magnet for sensor position sensing (omit for no magnet). |
| B | Rod type: B = male thread; blank = female thread. |
Replacement mapping (swap P for E): ACP→ACE, ASP→ASE, ATP→ATE, ACPD→ACED, ACPJ→ACEJ. ACP-family: ACP (double acting), ASP / ATP (single acting push / pull), ACPD (double rod), ACPJ (double rod, adjustable stroke).
The equal 206.2 N output in both directions lets one 25 mm bore cylinder press a bushing in and eject it, with no direction derating on the return stroke.
A 15 mm stroke and short ISO 21287 body fit inside cramped drill-jig clamps where a full-length profile cylinder would not clear the worktable.
The rear rod of the through-rod carries a proximity flag so a PLC can verify clamp-open state on a PCB test fixture; add the -S magnet code for CMSE / DMSE switches.
At 25 mm bore this sits between the 20 mm size (117.8 N at 0.5 MPa) and the 32 mm size (345.6 N at 0.5 MPa), so pick 25 when 206.2 N each way covers the job. The 15 mm stroke is well inside the 150 mm standard range for this bore. Note that a plain double-rod cylinder drifts when air is lost - add a rod lock or pilot check if the load must stay put. This unit has no magnet fitted; order the -S code if you need CMSE / DMSE switch positions. FA/FB flange or LB foot mounting bolts to the ISO 21287 face. Since ACPD25X15B is discontinued, order ACED25X15 as the current-production equivalent.
Replacement checklist
Because a rod exits both covers, force is equal both ways: 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) with 1.5 MPa (215 psi) proof pressure, and speed runs 30-500 mm/s.
The current-production replacement is ACED25X15, the ISO 21287 compact cylinder in the same 25 mm bore, 15 mm stroke and force class. Confirm the ISO 21287 mounting dimensions before swapping, since the ACP series was built to a DIN-standard footprint. FA/FB flange and LB foot brackets, plus the optional -S magnet for CMSE / DMSE switches, are ordered the same way.
