This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACED25X125SB, 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 ACPD25X125SB
The AirTAC ACPD Double Rod Compact Cylinder ACPD25X125SB is a double acting, double rod DIN-standard tight/compact air cylinder with a Ø25mm bore and 125mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACED25X125SB (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPD Double Rod Compact Cylinder ACPD25X125SB
Double acting with a rod leaving both covers, the ACPD25X125SB pushes and pulls with identical output: 206.2 N at 0.5 MPa and 288.6 N at 0.7 MPa in either direction, because both strokes work on the rod-side area of the 25 mm bore. The through-rod resists rotation and side load, and the rear rod end can carry a sensor flag while the front male thread drives the load. This model carries the optional -S magnet, so CMSE or DMSE reed and solid-state switches can be clipped on for end-of-stroke signalling. Note that it is discontinued; the current-production successor is the ACED25X125.
The short ISO 21287-class body saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, which is why it slots into tight jigs, guards and gantries. A fixed TPU bumper sits at each end to soften the stroke, and the hard-anodized aluminium body with an S45C hard-chrome rod runs on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi), 30-500 mm/s.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACED25X125SB (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 ACPD25X125SB Is Used
Symmetric fixture clamping
The equal 206.2 N force in both directions lets one cylinder clamp and release a machined housing in a drilling fixture with identical grip either way.
Reciprocating slide drive
A packaging machine's horizontal slide is driven and returned by the same through-rod, with the rear rod end carrying a flag for DMSE position switches.
Small parts press station
A 125 mm stroke presses bushings into plastic housings on an electronics assembly line, using about 123 N of practical working force at 0.5 MPa.
Replacing the Airtac ACPD Double Rod Compact Cylinder ACPD25X125SB with the ACED25X125SB
The 125 mm stroke sits inside the 150 mm standard range for this bore, so no made-to-order build is required. If the machine must hold position on air loss, add a rod lock or pilot check - a plain double-rod cylinder will drift. FA/FB flange or LB foot mounts bolt to the ISO 21287 face, and the male rod thread (B code) takes standard rod knuckles. Order the ACED25X125 as the direct replacement and confirm the ISO 21287 mounting dimensions before swapping, since the ACP is DIN-standard.
Replacement checklist
- ✓ Current-production ACE → ACED25X125SB
- ✓ 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 ACPD25X125SB FAQ
Yes - the double-rod design means both strokes use the rod-side area, so output is equal either way: 206.2 N at 0.5 MPa, 288.6 N at 0.7 MPa, and a maximum of 42.0 kgf at 1.0 MPa. Operating range is 0.15-1.0 MPa (22-145 psi) with a 1.5 MPa (215 psi) proof pressure, speed 30-500 mm/s, air filtered to 40 um.
Order the ACED25X125, the current-production ISO 21287 successor - swap the P for an E and you get the same 25 mm bore, 125 mm stroke and force class in a short compact body. Confirm the ISO 21287 mounting dimensions against your fixture first, since the ACP was built to the DIN standard. This unit already carries the -S magnet for CMSE / DMSE switches; on the replacement, add -S to keep that capability.
