This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACED25X40B, 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 ACPD25X40B
The AirTAC ACPD Double Rod Compact Cylinder ACPD25X40B is a double acting, double rod DIN-standard tight/compact air cylinder with a Ø25mm bore and 40mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACED25X40B (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPD Double Rod Compact Cylinder ACPD25X40B
A double acting compact cylinder with a rod through both covers, the ACPD25X40B delivers 206.2 N at 0.5 MPa in each direction, because both strokes work on the rod-side area. The 25 mm bore, 40 mm stroke body is hard-anodized aluminium with an S45C hard-chrome rod, a fixed TPU bumper at each end, and an M5x0.8 air port. The B code gives a male rod thread; the female-thread version drops the B.
The through-rod resists rotation and side load and gives a symmetric mount, so the rear rod can carry a sensor flag or a second tooling plate. The short ISO 21287-class body saves about 50% of the mounting length of an ISO 15552 profile cylinder, which suits tight jigs and guarding. At 0.5 MPa plan on roughly 124 N (about 12.6 kg) of usable vertical work rather than the full 206.2 N rating. This model is discontinued; the current direct is the ACED25X40, so confirm ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACED25X40B (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 ACPD25X40B Is Used
Reciprocating transfer slide
The equal 206.2 N push and pull at 0.5 MPa moves a small fixture back and forth on a 40 mm shuttle, with the rear rod driving a position flag between two CMSE switches on a -S unit.
Pick-and-place clamp on a robot arm
A male-thread rod end bolts straight to a gripper knuckle, and the symmetric through-rod mount keeps the clamp aligned on a compact electronics-assembly end effector.
Lab press for small parts
With about 12.6 kg of practical vertical force at 0.5 MPa, the 25 mm bore suits light test-rig pressing and sample holding where a full-length cylinder will not fit.
Replacing the Airtac ACPD Double Rod Compact Cylinder ACPD25X40B with the ACED25X40B
At 206.2 N per direction, 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, all equal both ways on the double-rod design. The 40 mm stroke is well inside the 150 mm standard range for bore 25, so no made-to-order stroke is needed. If a load must stay put when air is lost, add a rod lock or pilot check, since this cylinder drifts. Mounting: FA/FB flange, LB foot, CA/CB clevis, CR, SDB pivot or FTC. No magnet is fitted on this code, so CMSE / DMSE switches cannot be used; order the -S variant for that. Replacement: ACED25X40.
Replacement checklist
- ✓ Current-production ACE → ACED25X40B
- ✓ 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 ACPD25X40B FAQ
Yes, both directions are equal because a rod exits each cover and both strokes use the rod-side area. At 0.5 MPa it delivers 206.2 N, at 0.7 MPa it delivers 288.6 N in each direction, and the maximum at 1.0 MPa is 42 kgf. 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.
Order the ACED25X40, the current-production ISO 21287 successor: swap the P for an E and you get the same 25 mm bore, 40 mm stroke and force class. Because the ACP is DIN-standard, confirm the ISO 21287 mounting dimensions before swapping. Mounting hardware (FA/FB flange, LB foot, CA/CB clevis, CR, SDB, FTC) bolts to the same face family, and the -S magnet option enables CMSE / DMSE switches.
