This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACED32X20B, 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 ACPD32X20B
The AirTAC ACPD Double Rod Compact Cylinder ACPD32X20B is a double acting, double rod DIN-standard tight/compact air cylinder with a Ø32mm bore and 20mm stroke, 1/8" air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACED32X20B (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPD Double Rod Compact Cylinder ACPD32X20B
A double acting compact cylinder with a rod leaving both covers, the ACPD32X20B delivers 345.6 N in each direction at 0.5 MPa because both strokes work on the rod-side area of the 32 mm bore. The 20 mm stroke and short ISO 21287 body cut roughly 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight fixtures where a full-length body will not fit. The B code gives a male 12 mm rod thread on each end.
The through-rod resists rotation and side load and gives a symmetric mount, and the rear rod can carry a sensor flag in a pick-and-place head. A fixed TPU bumper sits at both ends, and speed runs 30-500 mm/s over 0.15-1.0 MPa (22-145 psi). Note that this model is discontinued: the current-production direct is ACED32X20, so confirm the ISO 21287 mounting dimensions before swapping. Without the optional -S code there is no magnet, so CMSE / DMSE switches cannot be fitted.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACED32X20B (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 (Ø32mm)
| Pressure | Force (both ways) |
|---|---|
| 0.5 MPa | 346 N |
| 0.7 MPa | 484 N |
| Max (@1.0 MPa) | 70 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 ACPD32X20B Is Used
Symmetric jig clamping
The male-threaded rods on both ends let a fixture clamp a machined aluminum housing from two sides with 345.6 N each way at 0.5 MPa, keeping the clamp forces balanced.
Reciprocating conveyor gates
A 20 mm stroke throws a sorting gate on a packaging line at 30-500 mm/s, and the through-rod holds the gate plate square without an external guide.
Pusher with rear flag mount
On an assembly bench, the back-end rod carries a sensor flag so a PLC tracks stroke position, while the front rod pushes 483.8 N at 0.7 MPa into a press-fit nest.
Replacing the Airtac ACPD Double Rod Compact Cylinder ACPD32X20B with the ACED32X20B
Size both ways: if 345.6 N at 0.5 MPa is more than the job needs, the ACPD25 bore gives 206.2 N; if you need more, the ACPD40 delivers 571.8 N. Both keep the same double-rod, equal-force behavior. Remember that a plain double-rod cylinder drifts when air is lost, so add a rod lock or pilot check for a held load. FA/FB flange or LB foot mounts bolt to the ISO 21287 face. Order the -S code if you want the magnet for CMSE / DMSE switches; this non-S model has none. For new projects, specify ACED32X20, the current replacement, and verify the ISO 21287 mounting dimensions.
Replacement checklist
- ✓ Current-production ACE → ACED32X20B
- ✓ 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 ACPD32X20B FAQ
No, push and pull are identical because a rod exits both covers and both strokes use the rod-side area of the 32 mm bore. At 0.5 MPa you get 345.6 N each way, at 0.7 MPa you get 483.8 N each way, and the maximum at 1.0 MPa is 70.5 kgf. Operating range is 0.15-1.0 MPa (22-145 psi) with a 1.5 MPa (215 psi) proof pressure.
The ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, with a hard-anodized aluminium body, S45C hard-chrome rod and fixed TPU bumpers at both ends. The ACPD family is discontinued; the current-production direct is ACED32X20 (swap the P for an E), which matches the same bore, stroke and force class. Confirm the ISO 21287 mounting dimensions before swapping, since the ACP is DIN-standard.
