This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACED25X35, 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 ACPD25X35
The AirTAC ACPD Double Rod Compact Cylinder ACPD25X35 is a double acting, double rod DIN-standard tight/compact air cylinder with a Ø25mm bore and 35mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACED25X35 (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPD Double Rod Compact Cylinder ACPD25X35
A double acting compact cylinder with a rod leaving both covers, the ACPD25X35 pushes and pulls with the same 206.2 N at 0.5 MPa because each stroke works on the rod-side area. The 25 mm bore and 35 mm stroke suit short-stroke tooling, and the through-rod resists rotation and light side load while the rear rod can carry a sensor flag. Its hard-anodized aluminium body and S45C hard-chrome rod run at 0.15-1.0 MPa (22-145 psi) and 30-500 mm/s.
The short ISO 21287-class body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight fixtures and guarding. Fixed TPU bumpers pad both ends of travel. Note this model is discontinued: the current direct is the ACED25X35, so confirm ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACED25X35 (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 ACPD25X35 Is Used
Fixture clamping
The symmetric 206.2 N push and pull at 0.5 MPa clamps small aluminium brackets in a machining fixture and retracts with equal force, with the 35 mm stroke clearing the part quickly.
Pusher on a packaging line
A through-rod pusher nudges cartons between conveyor lanes; the double rod resists side load from misaligned packs and the fixed TPU bumpers soften each end of the 35 mm travel.
Replacing the Airtac ACPD Double Rod Compact Cylinder ACPD25X35 with the ACED25X35
For a 35 mm stroke at this force class, 206.2 N at 0.5 MPa both ways covers light clamping and part transfer; step down to the 20 mm bore (117.8 N) for smaller loads or up to the 32 mm bore (345.6 N) when more force is needed. The cylinder does not hold position when air is lost, so add a rod lock or pilot check for a suspended load. This unit has no magnet; order the -S code if you need CMSE or DMSE switches. Since ACPD is discontinued, spec the ACED25X35 as the current replacement.
Replacement checklist
- ✓ Current-production ACE → ACED25X35
- ✓ 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 ACPD25X35 FAQ
Yes. Because a rod exits both covers, both strokes use the rod-side area: 206.2 N at 0.5 MPa and 288.6 N at 0.7 MPa in either direction, with a maximum of 42 kgf at 1.0 MPa. Operating range 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 with an M6x1.0 female rod thread.
Order the ACED25X35, the current-production ISO 21287 successor made by swapping the P for an E. It matches the same 25 mm bore, 35 mm stroke and force class, but confirm the ISO 21287 mounting dimensions against your fixture before swapping, since the ACP series was built to a DIN-standard body.
