This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACED25X45B, 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 ACPD25X45B
The AirTAC ACPD Double Rod Compact Cylinder ACPD25X45B is a double acting, double rod DIN-standard tight/compact air cylinder with a Ø25mm bore and 45mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACED25X45B (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPD Double Rod Compact Cylinder ACPD25X45B
A double acting, double-rod compact cylinder built to the DIN-standard ACP pattern, the ACPD25X45B pushes a 25 mm piston through a 45 mm stroke with a rod leaving both covers. Because each side works on the rod-side area, output is identical in both directions: 206.2 N at 0.5 MPa and 288.6 N at 0.7 MPa, with a peak of 42.0 kgf at 1.0 MPa. The through-rod resists rotation and side load, gives a symmetric mount, and leaves the rear rod free for a sensor flag. Air supply is 0.15-1.0 MPa (22-145 psi), speed 30-500 mm/s, and a fixed TPU bumper sits at each end.
The hard-anodized aluminium body with S45C hard-chrome rod keeps the mounting length roughly 50% shorter than an ISO 15552 profile cylinder, so it slots into tight fixtures and gantries. Note this model is discontinued: the current-production direct is the ISO 21287 ACED25X45, so confirm mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACED25X45B (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 ACPD25X45B Is Used
Symmetric jig clamping
The through-rod clamps a machined aluminum bracket from either side with an equal 206.2 N, so one cylinder replaces two in a drilling fixture.
Bidirectional pusher on a packaging line
Equal force both ways lets the same 45 mm stroke divert cartons left or right at 30-500 mm/s without recalibrating pressure.
Rear-rod flag sensing on a test bench
The back-end rod carries a flag past a switch on a leak-test rig, giving position feedback while the front rod loads the part.
Replacing the Airtac ACPD Double Rod Compact Cylinder ACPD25X45B with the ACED25X45B
At 206.2 N per side, the 25 mm bore suits clamping and transfer tasks in the 10-20 kg range; step down to the 20 mm bore (117.8 N) for lighter jigs or up to the 32 mm bore (345.6 N) when more force is needed. The 45 mm stroke sits well inside the 150 mm standard maximum for this bore. This unit has a male rod thread (B code) and no magnet, so position sensing requires the -S variant with CMSE / DMSE switches. Since the piston drifts when air is lost, add a rod lock or pilot check for held loads, and specify the ACED25X45 for new projects.
Replacement checklist
- ✓ Current-production ACE → ACED25X45B
- ✓ 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 ACPD25X45B FAQ
It is a double-rod cylinder, so force is equal in both directions: 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. Both strokes use the rod-side area, so there is no push-versus-pull difference. Operating range is 0.15-1.0 MPa (22-145 psi) with a 1.5 MPa (215 psi) proof pressure.
The hard-anodized aluminium body is an ISO 21287-class short build, cutting mounting length by about 50% versus an ISO 15552 profile cylinder, with FA/FB flange or LB foot mounting and a fixed TPU bumper at each end. The ACPD family is discontinued; the current direct is the ACED25X45 in the same bore, stroke and force class. Confirm the ISO 21287 mounting dimensions before swapping, since the ACP follows the DIN standard.
