This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACED25X75S, 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 ACPD25X75S
The AirTAC ACPD Double Rod Compact Cylinder ACPD25X75S is a double acting, double rod DIN-standard tight/compact air cylinder with a Ø25mm bore and 75mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACED25X75S (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPD Double Rod Compact Cylinder ACPD25X75S
Double acting with a rod leaving both covers, the ACPD25X75S pushes and pulls with identical force because each stroke works on the rod-side area: 206.2 N at 0.5 MPa and 288.6 N at 0.7 MPa in either direction. The 25 mm bore drives a 10 mm through-rod over a 75 mm stroke, and the back-end rod gives you a free spot for a sensor flag or a symmetric second mount. This model carries the optional -S magnet, so CMSE or DMSE reed and solid-state switches can be clipped straight onto the body. Note that it is discontinued; the current direct is the ISO 21287 ACED25X75.
The short ISO 21287-class body saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, which is why it suits tight jigs, guards and gantries. A fixed TPU bumper sits at each end, the hard-anodized aluminium body carries an S45C hard-chrome rod, and speed runs 30-500 mm/s at 0.15-1.0 MPa (22-145 psi). Air supply should be filtered to 40 um.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACED25X75S (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 ACPD25X75S Is Used
Fixture clamping in tight jigs
The 206.2 N bidirectional force and 75 mm stroke clamp or release small workpieces in machining jigs where the short body saves about 50% of the length of an ISO 15552 profile cylinder.
Push-push transfer between conveyors
A rod on both covers lets one cylinder divert cartons or trays in either direction with equal 288.6 N force at 0.7 MPa, no reverse plumbing needed.
Position feedback on assembly stations
The fitted -S magnet accepts CMSE or DMSE switches, so the back-end rod can carry a flag for end-of-stroke confirmation on electronics assembly lines.
Replacing the Airtac ACPD Double Rod Compact Cylinder ACPD25X75S with the ACED25X75S
At 206.2 N per side at 0.5 MPa, the 25 mm bore suits light clamping and transfer work; step down to the 16 mm bore (75.4 N) for smaller loads or up to the 32 mm bore (345.6 N) when more force is needed. The through-rod resists rotation and light side load, and the female M6x1.0 rod thread takes standard I/Y knuckles. Remember the piston drifts if air is lost - add a rod lock or pilot check where a load must be held. FA/FB flange and LB foot mountings bolt to the ISO 21287 face. Since ACPD25X75S is discontinued, order ACED25X75 and confirm the ISO 21287 mounting dimensions before swapping, as the ACP is DIN-standard.
Replacement checklist
- ✓ Current-production ACE → ACED25X75S
- ✓ 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 ACPD25X75S FAQ
Because it is a double-rod cylinder, output 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 push never exceeds pull. Operating range is 0.15-1.0 MPa (22-145 psi) with a 1.5 MPa (215 psi) proof pressure.
The current-production successor is the ISO 21287 ACED25X75 - swap the P for an E - which matches the same 25 mm bore, 75 mm stroke and force class with a short body. Confirm the ISO 21287 mounting dimensions before swapping, since the ACP is DIN-standard. FA/FB flange and LB foot options and the optional -S magnet for CMSE / DMSE switches carry over.
