This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACED12X90B, 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 ACPD12X90B
The AirTAC ACPD Double Rod Compact Cylinder ACPD12X90B is a double acting, double rod DIN-standard tight/compact air cylinder with a Ø12mm bore and 90mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACED12X90B (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPD Double Rod Compact Cylinder ACPD12X90B
A double acting compact cylinder with a rod exiting both covers, the ACPD12X90B delivers an identical 42.4 N in each direction at 0.5 MPa (59.4 N at 0.7 MPa) because both strokes work on the rod-side area. The through-rod resists rotation and light side load, gives a symmetric mounting point at each end, and the rear rod can carry a sensor flag. The 90 mm stroke is longer than the 50 mm standard limit for a 12 mm bore, so it is a made-to-order build.
The hard-anodized aluminium body with an S45C hard-chrome rod keeps the short ISO 21287-class format, which saves about 50% of the mounting length of an ISO 15552 profile cylinder - useful in slim pick-and-place heads and compact fixtures. A fixed TPU bumper sits at each end, and this model is discontinued: the current direct is the ACED12X90, so confirm ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACED12X90B (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 (Ø12mm)
| Pressure | Force (both ways) |
|---|---|
| 0.5 MPa | 42 N |
| 0.7 MPa | 59 N |
| Max (@1.0 MPa) | 9 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 ACPD12X90B Is Used
Twin-sided ejection in small jigs
The through-rod pushes a 20 g plastic clip out of a machining fixture from either end with the same 42.4 N at 0.5 MPa, so one cylinder replaces two single-rod units in a tight jig plate.
Sensor-flag carrier on a compact gantry
The rear rod of the 6 mm through-rod mounts a position flag in a slim Z-axis head where the short body saves about 50% of the length of an ISO 15552 profile cylinder.
Symmetric push-pull in electronics assembly
A benchtop PCB test fixture uses the equal 59.4 N at 0.7 MPa in both directions to clamp and release a lid, with the male M3x0.5 rod thread bolting straight to the tooling stud.
Replacing the Airtac ACPD Double Rod Compact Cylinder ACPD12X90B with the ACED12X90B
For a 12 mm bore job needing equal force both ways, this unit gives 42.4 N at 0.5 MPa; step up to the 16 mm bore (75.4 N) if you need more, or drop to a single-rod ACP if the rear rod is not required. The B code gives a male M3x0.5 rod thread; omit B for the female version. The 90 mm stroke exceeds the 50 mm standard maximum for this bore, so expect a non-standard order. There is no magnet on this model - order the -S code if you want CMSE / DMSE switch capability. This cylinder is discontinued; the ACED12X90 is the current-production replacement in the same bore, stroke and force class.
Replacement checklist
- ✓ Current-production ACE → ACED12X90B
- ✓ 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 ACPD12X90B FAQ
Because a rod exits both covers, output is equal both ways: 42.4 N at 0.5 MPa and 59.4 N at 0.7 MPa, with a maximum of 8.6 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, temperature -20 to +70 C, air filtered to 40 um, and the port is M5x0.8. The 90 mm stroke is a made-to-order length above the 50 mm standard maximum for this bore.
The short ISO 21287-class aluminium body saves about 50% of the mounting length of an ISO 15552 profile cylinder, and a fixed TPU bumper at each end decelerates the piston at the ends of travel - it is not adjustable and never holds a load when air is lost. This ACPD model is discontinued; the ACED12X90 is the current direct successor in the same bore, stroke and force class, so confirm the ISO 21287 mounting dimensions before ordering.
