This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACED25X25B, 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 ACPD25X25B is a double acting, double rod DIN-standard tight/compact air cylinder with a Ø25mm bore and 25mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACED25X25B (ISO 21287 ACE), in the same bore, stroke and force class.
A double acting compact cylinder with a through rod, the ACPD25X25B pushes and pulls with identical force because a piston rod exits both covers and both strokes work on the rod-side area. At 0.5 MPa that is 206.2 N in each direction, rising to 288.6 N at 0.7 MPa, from a 25 mm bore with a 25 mm stroke and a 10 mm rod. The male rod thread (B code) bolts straight to your tooling, and a fixed TPU bumper sits at each end of the hard-anodized aluminium body.
Because the body follows the short DIN-standard format, it saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, which is why it suits tight jigs and guarding where a full-length body will not fit. The through rod also resists rotation and side load and gives a symmetric mount, and the rear rod can carry a sensor flag. Note the magnet is the optional -S code: this unit has no magnet, so CMSE or DMSE switches cannot be used unless -S is ordered. This model is discontinued; the current-production direct is ACED25X25, so confirm ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACED25X25B (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. |
| ×25 | 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 206.2 N equal push and pull clamps a machined aluminium bracket from both sides of a drilling fixture, with the male rod thread taking a custom clamp pad directly.
A 25 mm stroke drives a small parts-transfer slide back and forth at 30-500 mm/s, where identical force in both directions keeps return speed consistent under load.
The rear rod carries a sensor flag on a compact pick-and-place head; order the -S magnet code if CMSE or DMSE switches are required for end-of-stroke detection.
At 206.2 N per side, the 25 mm bore sits between the 20 mm bore (117.8 N) and the 32 mm bore (345.6 N) at 0.5 MPa, so step up to 32 mm if your fixture needs more than about 124 N of usable force. The 25 mm stroke is well inside the 150 mm maximum standard stroke for this bore, so no made-to-order length is involved. A plain through-rod cylinder does not hold position when air is lost - the piston drifts - so add a rod lock or pilot check for a held load. If you need position feedback, order the -S version with the magnet for CMSE / DMSE switches. For new projects, specify the ACED25X25 instead: it is the current ISO 21287 successor in the same bore, stroke and force class.
Replacement checklist
Yes - the double-rod design means a rod exits both covers, so both strokes use the rod-side area. Output is 206.2 N at 0.5 MPa and 288.6 N at 0.7 MPa, equal in push and pull, with a maximum of 42.0 kgf at 1.0 MPa. Operating range is 0.15-1.0 MPa (22-145 psi) with proof pressure of 1.5 MPa (215 psi), running on air filtered to 40 um at 30-500 mm/s.
The short DIN-standard body saves about 50% of the mounting length of an ISO 15552 profile cylinder, with a fixed TPU bumper at each end and FA/FB flange or LB foot mounting. The ACPD25X25B is discontinued; the current-production replacement is ACED25X25 (swap the P for an E) in the same bore, stroke and force class - confirm the ISO 21287 mounting dimensions before swapping, since the ACP follows the older DIN-standard footprint.
