This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACED25X25SB, 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 ACPD25X25SB
The AirTAC ACPD Double Rod Compact Cylinder ACPD25X25SB 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 ACED25X25SB (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPD Double Rod Compact Cylinder ACPD25X25SB
A double acting compact cylinder with a rod through both covers, the ACPD25X25SB pushes and pulls with the same 206.2 N at 0.5 MPa because both strokes work on the rod-side area. The 25 mm bore and 25 mm stroke suit short, symmetric moves in tight fixtures, and the male rod thread (B code) bolts straight to standard rod knuckles. Its hard-anodized aluminium body is about 50% shorter in mounting length than an ISO 15552 profile cylinder, so it slots into jigs and gantries where a full-length body will not fit.
The through-rod resists rotation and light side load, and the rear rod can carry a sensor flag or a second tool. This model carries the optional -S magnet, so CMSE / DMSE reed or solid-state switches mount directly on the body. A fixed TPU bumper at each end decelerates the piston, and speed spans 30-500 mm/s at 0.15-1.0 MPa (22-145 psi). Note that this ACPD model is discontinued: the current-production direct is ACED25X25 in the same bore, stroke and force class - confirm the ISO 21287 mounting dimensions before swapping, since the ACP is DIN-standard. As a rule of thumb, plan on about 123 N (roughly 12 kg) of real work at 0.5 MPa rather than the full rating.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACED25X25SB (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 ACPD25X25SB Is Used
Symmetric part transfer in machining fixtures
The through-rod lets a CNC fixture grip or release a 12 kg workpiece from either side with the same 206.2 N clamping force at 0.5 MPa, no orientation change needed.
Position-verified ejection on packaging lines
With the -S magnet fitted, CMSE or DMSE switches confirm each 25 mm eject stroke of a carton pusher running at up to 500 mm/s before the next cycle starts.
Reciprocating sample shuttle in lab automation
The rear rod drives a sensor flag while the front rod shuttles a vial tray, and the short ISO 21287-class body fits inside a compact analyzer enclosure.
Replacing the Airtac ACPD Double Rod Compact Cylinder ACPD25X25SB with the ACED25X25SB
For a 25 mm stroke with equal force in both directions, this double-rod 25 mm bore delivers 206.2 N at 0.5 MPa and 288.6 N at 0.7 MPa each way. If your load needs less, the ACPD20X25SB gives 117.8 N; if it needs more, step up to ACPD32X25SB at 345.6 N. Remember the piston drifts when air is lost - add a rod lock or pilot check if the load must stay put. The male rod thread suits I/Y knuckles, and the -S magnet this model carries lets you fit CMSE / DMSE switches for end-position sensing. Since ACPD is discontinued, order ACED25X25 as the current replacement and verify the ISO 21287 mounting dimensions against your fixture.
Replacement checklist
- ✓ Current-production ACE → ACED25X25SB
- ✓ 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 ACPD25X25SB 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. Operating pressure is 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), speed 30-500 mm/s, and the port is M5x0.8.
The ACPD family is no longer in production. The current direct is ACED25X25 - swap the P for an E - which matches the same 25 mm bore, 25 mm stroke and force class in the ISO 21287 short-body format. Confirm the ISO 21287 mounting dimensions against your ACP footprint before swapping, and note that the magnet is an option on the ACE family, so add the -S code if you need CMSE / DMSE switch sensing.
