This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACED25X50, 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 ACPD25X50
The AirTAC ACPD Double Rod Compact Cylinder ACPD25X50 is a double acting, double rod DIN-standard tight/compact air cylinder with a Ø25mm bore and 50mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACED25X50 (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPD Double Rod Compact Cylinder ACPD25X50
A double acting compact cylinder with a rod leaving both covers, the ACPD25X50 delivers the same 206.2 N at 0.5 MPa in each direction because both strokes work on the rod-side area. The 25 mm bore pushes 288.6 N at 0.7 MPa, with a peak of 42.0 kgf at 1.0 MPa.
The hard-anodized aluminium body and S45C hard-chrome rod keep the short ISO 21287-class body about 50% shorter in mounting length than an ISO 15552 profile cylinder, so it slots into tight fixtures and gantries. The through-rod resists rotation and side load, and the rear rod can carry a sensor flag. Fixed TPU bumpers sit at both ends, speed runs 30-500 mm/s, and the magnet is only present when you order the optional -S code for CMSE / DMSE switches. This model is discontinued; the current-production replacement is ACED25X50.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACED25X50 (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 ACPD25X50 Is Used
Reciprocating test slide
The through-rod drives a slide equally in both directions on an electronics test bench, with the rear rod carrying a flag for position sensing when the -S magnet is ordered.
Symmetric press fixture
Equal 206.2 N force each way suits a small assembly press that must seat a part on the forward stroke and eject it on the return, within the 50 mm travel.
Compact indexing unit
The short body fits inside a rotary indexing dial where a full-length cylinder will not, with LB foot mounting and 30-500 mm/s cycle speed.
Replacing the Airtac ACPD Double Rod Compact Cylinder ACPD25X50 with the ACED25X50
At 206.2 N per side, this 25 mm double-rod unit suits balanced push-pull jobs; step down to the 20 mm bore (117.8 N) for lighter clamps or up to the 32 mm bore (345.6 N) when more force is needed. It will not hold position if air is lost, so add a rod lock or pilot check for a suspended load. FA/FB flange or LB foot mounting bolts to the standard face, and the optional -S magnet enables CMSE / DMSE switches. Before swapping in the ACED25X50 replacement, confirm the ISO 21287 mounting dimensions.
Replacement checklist
- ✓ Current-production ACE → ACED25X50
- ✓ 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 ACPD25X50 FAQ
Because it is a double-rod cylinder, output is identical both ways: 206.2 N at 0.5 MPa and 288.6 N at 0.7 MPa on the rod-side area, peaking at 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, air filtered to 40 um, -20 to +70 C, and speed 30-500 mm/s. Port is M5x0.8, rod thread is female M6x1.0, and the 50 mm stroke sits within the 150 mm maximum standard stroke for this bore.
No - this model is discontinued. The current-production direct is ACED25X50 (swap the P for an E), which matches the same 25 mm bore, 50 mm stroke and force class in the ISO 21287 family. Confirm the ISO 21287 mounting dimensions against your fixture before swapping, since the ACP was built to a DIN-standard footprint.
