This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACED25X175B, 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 ACPD25X175B
The AirTAC ACPD Double Rod Compact Cylinder ACPD25X175B 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 ACED25X175B (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPD Double Rod Compact Cylinder ACPD25X175B
This double acting compact cylinder carries a rod through BOTH covers, so its 25 mm bore delivers an identical 206.2 N at 0.5 MPa and 288.6 N at 0.7 MPa on every stroke, since both faces work on the rod-side area. The 175 mm stroke is longer than the 150 mm standard limit for bore 25, so it is a made-to-order build. The B code gives a male M6x1.0 rod thread on each end, and the fixed TPU bumper pads at both covers simply soften end-of-travel contact. Note this model is discontinued; the current-production successor is ACED25X175.
The hard-anodized aluminium body keeps the mounting length roughly 50% shorter than an ISO 15552 profile cylinder, which is why this size suits tight gantries and fixture slides where a full-length body cannot fit. The through-rod resists rotation and side load and lets the rear rod carry a sensor flag or a counter-grip. Air supply is 0.15-1.0 MPa (22-145 psi) and speed runs 30-500 mm/s.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACED25X175B (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 ACPD25X175B Is Used
Bidirectional parts transfer
The rear rod pushes a machined aluminum bracket off a fixture while the front rod returns a pallet, both directions delivering the same 206.2 N at 0.5 MPa.
Compact slide on a PCB line
A 175 mm through-rod slide positions a camera head inside a tight inspection gantry, the short body fitting where a full-length profile cylinder cannot.
Flag-driven stroke sensing
With the optional -S magnet ordered, a CMSE switch on the body plus a flag on the rear rod confirms full retraction of a glue-head carriage.
Replacing the Airtac ACPD Double Rod Compact Cylinder ACPD25X175B with the ACED25X175B
At 206.2 N per side at 0.5 MPa, bore 25 sits between bore 20 (117.8 N) and bore 32 (345.6 N), so pick 25 when 20 is marginal and 32 is oversized. The through-rod suits symmetric clamping and guided slides; if the load must stay put on air loss, add a rod lock or pilot check, because this cylinder drifts when depressurized. FA/FB flange or LB foot mounts bolt to the standard face, and the optional -S magnet enables CMSE / DMSE switches - this unit has no magnet fitted. Since ACPD is discontinued, order ACED25X175 and confirm the ISO 21287 mounting dimensions before the swap.
Replacement checklist
- ✓ Current-production ACE → ACED25X175B
- ✓ 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 ACPD25X175B FAQ
Because a rod exits both covers, output 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. The bore is 25 mm, stroke 175 mm (non-standard; bore 25 standard tops out at 150 mm), rod 10 mm with male M6x1.0 threads, port M5x0.8, pressure 0.15-1.0 MPa (22-145 psi), speed 30-500 mm/s, and fixed TPU bumpers at both ends.
Strokes beyond 150 mm for bore 25 are made to order, so this model is built on request. Since the ACPD family is discontinued, the practical route is the current-production ACED25X175, which matches the same bore, stroke and force class in the ISO 21287 compact format - just confirm the mounting dimensions against your fixture first, because the ACP follows the older DIN-standard layout.
