This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACED25X120SB, 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 ACPD25X120SB
The AirTAC ACPD Double Rod Compact Cylinder ACPD25X120SB is a double acting, double rod DIN-standard tight/compact air cylinder with a Ø25mm bore and 120mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACED25X120SB (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPD Double Rod Compact Cylinder ACPD25X120SB
The ACPD25X120SB is a double acting, double-rod compact cylinder: a piston rod exits both covers, so the through-rod resists rotation and side load and the back-end rod can carry a sensor flag. Output force is equal in both directions because both strokes use the rod-side area - 206.2 N at 0.5 MPa and 288.6 N at 0.7 MPa. The 25 mm bore pushes with the same force whether it extends or retracts, which suits symmetric clamping and reciprocating transfer strokes. This model carries the optional -S magnet, so CMSE or DMSE reed and solid-state switches can be mounted for end-of-stroke sensing.
Its hard-anodized aluminium body is an ISO 21287 short-body build that saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight jigs, guards and gantries. A fixed TPU bumper sits at both ends and the S45C hard-chrome rod runs at 30-500 mm/s on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi). Note that the ACPD family is discontinued: the current-production direct is the ACED25X120, so confirm ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACED25X120SB (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 ACPD25X120SB Is Used
Reciprocating transfer between two stations
A 120 mm through-rod stroke shuttles PCB trays on an electronics assembly line; the equal 206.2 N force in both directions keeps return speed and push identical, and CMSE switches on the -S magnet confirm each end position.
Symmetric clamping of machined housings
On a CNC fixture, the rod-side piston clamps an aluminium pump housing from one side while the back-end rod drives an opposing rest pad, using the same 288.6 N at 0.7 MPa on both faces.
Pusher on a bottling conveyor
A food-line diverter nudges off-spec bottles into a reject chute; the short ISO 21287 body fits under the side guard where a full-length profile cylinder will not, and the fixed TPU bumpers soften each 120 mm hit.
Replacing the Airtac ACPD Double Rod Compact Cylinder ACPD25X120SB with the ACED25X120SB
At 206.2 N per side at 0.5 MPa, the 25 mm bore sits between the 20 mm bore (117.8 N) and the 32 mm bore (345.6 N) - step down for lighter pick-and-place arms, step up for heavier press-fit fixtures. The 120 mm stroke is within the 150 mm standard range for this bore, so no made-to-order build is needed. Because a plain double-rod cylinder drifts when air is lost, add a rod lock or pilot check if the load must stay held. The male rod thread (B code) takes I/Y knuckles directly, FA/FB flange or LB foot mounts bolt to the ISO 21287 face, and the fitted -S magnet works with CMSE / DMSE switches. Order the ACED25X120 as the current replacement and verify mounting dimensions against the datasheet.
Replacement checklist
- ✓ Current-production ACE → ACED25X120SB
- ✓ 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 ACPD25X120SB 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 and 288.6 N at 0.7 MPa, with a maximum of 42.0 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 120 mm stroke sits inside the 150 mm standard limit for the 25 mm bore.
This model is no longer in production. The current direct is the ACED25X120 (swap the P for an E), which matches the same 25 mm bore, 120 mm stroke and force class - confirm the ISO 21287 mounting dimensions before swapping, since the ACP is DIN-standard. This unit carries the optional -S magnet, so CMSE or DMSE reed and solid-state switches mount directly for end-of-stroke detection.
