This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACED25X100S, 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 ACPD25X100S
The AirTAC ACPD Double Rod Compact Cylinder ACPD25X100S is a double acting, double rod DIN-standard tight/compact air cylinder with a Ø25mm bore and 100mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACED25X100S (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPD Double Rod Compact Cylinder ACPD25X100S
A double acting compact cylinder with a piston rod leaving both covers, the ACPD25X100S delivers an identical 206.2 N at 0.5 MPa (288.6 N at 0.7 MPa) on every stroke, because both chambers work on the rod-side area. The through-rod resists rotation and side load, gives a symmetric mounting face, and the rear rod can carry a sensor flag. The 100 mm stroke sits inside the 150 mm standard range for this 25 mm bore, and the short ISO 21287-class body saves roughly 50% of the mounting length of an ISO 15552 profile cylinder.
The S code means the optional magnet is fitted on this unit, so CMSE or DMSE reed and solid-state switches can be clipped on for end-of-stroke detection. A fixed TPU bumper pads both ends, the hard-anodized aluminium body carries an S45C hard-chrome rod, and the female M6x1.0 rod thread plus M5x0.8 ports keep plumbing simple. Note this model is discontinued: the current-production direct is ACED25X100, so confirm the ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACED25X100S (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 ACPD25X100S Is Used
Fixture clamping on a CNC jig
The symmetric through-rod clamps a machined aluminium bracket from both sides of a drilling fixture, with the 206.2 N per side at 0.5 MPa holding the part square while the 100 mm stroke clears loading.
Bidirectional pusher on a packaging line
Equal force in both directions lets the same cylinder divert cartons left or right on a conveyor, with CMSE switches on the fitted magnet confirming each completed stroke.
Sensor flag carriage in a test rig
The rear rod carries a flag past a photoelectric sensor to index a 100 mm test cycle, while the front rod drives the probe; the fixed TPU bumpers soften both ends at up to 500 mm/s.
Replacing the Airtac ACPD Double Rod Compact Cylinder ACPD25X100S with the ACED25X100S
At 206.2 N per side at 0.5 MPa this bore suits light clamping and transfer tasks; drop to the 20 mm bore (117.8 N) for tighter loads or step up to 32 mm (345.6 N) when more force is needed. Because the piston drifts when air is lost, add a rod lock or pilot check valve if the load must stay put. The 100 mm stroke is standard (max 150 mm for this bore), FA/FB flange or LB foot mounts bolt to the ISO 21287 face, and CMSE/DMSE switches work thanks to the fitted -S magnet. For new projects order ACED25X100, the current replacement.
Replacement checklist
- ✓ Current-production ACE → ACED25X100S
- ✓ 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 ACPD25X100S FAQ
Yes. As a double-rod cylinder both strokes use the rod-side area, so output is equal in extend and retract: 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 100 mm stroke is within the 150 mm standard limit for this bore.
This model is discontinued and no longer in production. The current direct is ACED25X100, the ISO 21287 successor in the same bore, stroke and force class. Check the ISO 21287 mounting dimensions against your fixture before swapping, since the ACP follows the older DIN-standard body. The ACED keeps FA/FB flange and LB foot options and accepts CMSE/DMSE switches where the -S magnet is ordered.
