This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACED12X45, 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 ACPD12X45
The AirTAC ACPD Double Rod Compact Cylinder ACPD12X45 is a double acting, double rod DIN-standard tight/compact air cylinder with a Ø12mm bore and 45mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACED12X45 (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPD Double Rod Compact Cylinder ACPD12X45
A double acting compact cylinder with a rod leaving both covers, the ACPD12X45 pushes and pulls with identical output: 42.4 N at 0.5 MPa (59.4 N at 0.7 MPa) in either direction, because both strokes work on the rod-side area of the 12 mm bore. The through-rod resists rotation and light side load, gives a symmetric mounting point, and leaves the rear rod free to carry a sensor flag. A fixed TPU bumper sits at each end, and stroke speed runs from 30 to 500 mm/s.
The hard-anodized aluminium body with an S45C hard-chrome rod is an ISO 21287 short build, saving roughly 50% of the mounting length of an ISO 15552 profile cylinder, which suits cramped lab fixtures and small assembly heads. Note this model is discontinued: the current-production direct is the ACED12X45, so confirm ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACED12X45 (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).

Replacement mapping (swap P for E): ACP→ACE, ASP→ASE, ATP→ATE, ACPD→ACED, ACPJ→ACEJ. ACP-family: ACP (double acting), ASP / ATP (single acting push / pull), ACPD (double rod), ACPJ (double rod, adjustable stroke).
Where the Airtac ACPD Double Rod Compact Cylinder ACPD12X45 Is Used
Lab sample transfer
The 42.4 N bidirectional output and 45 mm stroke shuttle microscope slides or vial trays between stations on compact benchtop analyzers.
Micro part ejection
A rear-rod sensor flag (with the -S magnet option) confirms ejection of small stamped contacts from a die or nest at up to 500 mm/s.
Push-pull gate actuator
Equal force in both directions makes the through-rod ideal for sliding a small guard or chute diverter where push and pull loads match.
Replacing the Airtac ACPD Double Rod Compact Cylinder ACPD12X45 with the ACED12X45
For a 45 mm stroke at this force level, the 12 mm bore delivers 42.4 N both ways at 0.5 MPa; step down is not available in this family, while the 16 mm bore gives 75.4 N if you need headroom. The 45 mm stroke sits inside the 50 mm maximum standard stroke for this bore, so no made-to-order build is required. This unit has no magnet fitted, so CMSE or DMSE switches cannot be used; order the -S code (ACPD12X45S) if position sensing matters. Since the piston drifts when air is lost, add a rod lock or pilot check for held loads. For new projects, specify the ACED12X45 instead.
Replacement checklist
- ✓ Current-production ACE → ACED12X45
- ✓ 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 ACPD12X45 FAQ
Output is equal both ways because a rod exits each cover and both strokes use the rod-side area: 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, port M5x0.8, female rod thread M3x0.5, rod 6 mm.
Only if the optional -S magnet is ordered (ACPD12X45S); this version has no magnet, so no CMSE or DMSE switch can be mounted. Also note the model is discontinued - the current replacement is the ACED12X45, an ISO 21287 direct of the same bore, stroke and force class. Confirm the mounting dimensions before converting.
