This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACED25X175, 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 ACPD25X175
The AirTAC ACPD Double Rod Compact Cylinder ACPD25X175 is a double acting, double rod DIN-standard tight/compact air cylinder with a Ø25mm bore and 175mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACED25X175 (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPD Double Rod Compact Cylinder ACPD25X175
A double acting compact cylinder with a rod leaving both covers, the ACPD25X175 pushes and pulls with identical output: 206.2 N at 0.5 MPa and 288.6 N at 0.7 MPa in each direction, because both strokes work on the rod-side area. The through-rod resists rotation and light side load, gives a symmetric mounting point, and the rear rod can carry a sensor flag. A fixed TPU bumper sits at each end and the body is hard-anodized aluminium with an S45C hard-chrome rod.
The 175 mm stroke is longer than the 150 mm standard limit for a 25 mm bore, so this unit is made to order. Note the short ISO 21287-class body still saves about 50% of the mounting length of an ISO 15552 profile cylinder, useful in tight gantries. This model is discontinued; the current direct is ACED25X175 - confirm ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACED25X175 (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 ACPD25X175 Is Used
Reciprocating transfer slide
The through-rod drives a light pallet slide back and forth on a small assembly line, with equal 206.2 N force in both directions so return speed and push match without extra regulation.
Flag-operated position station
On a packaging machine gate, the rear rod carries a flag past a switch (order the -S magnet version for CMSE / DMSE) while the front rod does the work, all within a short body.
Press-fit locating clamp
A fixture on an electronics assembly bench uses the 288.6 N at 0.7 MPa to seat small connectors, with the symmetric rod keeping the tooling plate square.
Replacing the Airtac ACPD Double Rod Compact Cylinder ACPD25X175 with the ACED25X175
At 206.2 N per side at 0.5 MPa, this bore suits light clamping and transfer tasks; step down to the 20 mm bore (117.8 N) for smaller loads or up to the 32 mm bore (345.6 N) if you need more margin. The 175 mm stroke is a non-standard, made-to-order length. Mounting is FA/FB flange or LB foot, and the female M6x1.0 rod thread takes standard I/Y knuckles. If you need position sensing, order the -S variant with the optional magnet for CMSE / DMSE switches - this base code has no magnet. Like any plain double-rod cylinder it will drift when air is lost, so add a rod lock or pilot check for a held load. For new projects, specify ACED25X175, the current-production replacement.
Replacement checklist
- ✓ Current-production ACE → ACED25X175
- ✓ 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 ACPD25X175 FAQ
It is a double-rod cylinder, so output is identical both ways: 206.2 N at 0.5 MPa, 288.6 N at 0.7 MPa, and up to 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, port M5x0.8, rod thread M6x1.0 female.
Standard strokes for the 25 mm bore stop at 150 mm, so 175 mm is a made-to-order build. Since the whole ACPD family is discontinued, the practical route is the current ACED25X175, the ISO 21287 successor in the same bore, stroke and force class - just confirm the mounting dimensions against your fixture first.
