This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACED32X40B, 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 ACPD32X40B
The AirTAC ACPD Double Rod Compact Cylinder ACPD32X40B is a double acting, double rod DIN-standard tight/compact air cylinder with a Ø32mm bore and 40mm stroke, 1/8" air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACED32X40B (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPD Double Rod Compact Cylinder ACPD32X40B
A double acting compact cylinder with a rod leaving both covers, the ACPD32X40B delivers 345.6 N in each direction at 0.5 MPa because both strokes work on the rod-side area. The 12 mm through-rod resists rotation and side load, gives a symmetric mounting point, and lets the rear rod carry a sensor flag. Its short ISO 21287-class body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight jigs and guarding where a full-length body will not fit.
The hard-anodized aluminium body carries S45C hard-chrome rods, fixed TPU bumpers at both ends, and a 1/8" port. Running on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi), it cycles at 30-500 mm/s between -20 and +70 C. At 0.7 MPa output rises to 483.8 N both ways. Note this model is discontinued: the current-production direct is the ACED32X40, so confirm ISO 21287 mounting dimensions before swapping. Since the piston drifts when air is lost, add a rod lock or pilot check if a load must stay put.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACED32X40B (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 ACPD32X40B Is Used
Symmetric push-pull fixture
A 40 mm stroke through-rod clamps and releases a machined aluminium housing in a CNC jig, applying 345.6 N identically on both strokes so the fixture behavior never changes with direction.
Dual-side conveyor diverter
Rods on both covers push a 6 kg carton off a 400 mm belt from either end, with the rear rod doubling as a mount for a flag when the -S magnet option is ordered.
Lab test slide actuator
A bench-top fatigue rig strokes a specimen tray at 30-500 mm/s, using the equal 483.8 N at 0.7 MPa in both directions for symmetric load-unload cycles.
Replacing the Airtac ACPD Double Rod Compact Cylinder ACPD32X40B with the ACED32X40B
Size both ways: if 345.6 N per side at 0.5 MPa is more than the job needs, the ACPD25X40B gives 206.2 N; if you need headroom, the ACPD40X40B reaches 571.8 N. The B code gives a male M8x1.25 rod thread; FA/FB flange or LB foot mounts bolt to the standard face. No magnet is fitted on this code - order the -S version if you need CMSE / DMSE switch positions. For new builds, specify the ACED32X40 instead.
Replacement checklist
- ✓ Current-production ACE → ACED32X40B
- ✓ 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 ACPD32X40B FAQ
Yes - the double-rod design means both strokes use the rod-side area, so output is equal each way: 345.6 N at 0.5 MPa and 483.8 N at 0.7 MPa, with a maximum of 70.5 kgf at 1.0 MPa. Operating pressure is 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), and speed range 30-500 mm/s. The 12 mm rod has a male thread (B code) and the port is 1/8".
This model is no longer in production. The current direct is the ACED32X40 - swap the P for an E - which matches the same 32 mm bore, 40 mm stroke and force class in the ISO 21287 family. Because the ACP is DIN-standard, confirm the ISO 21287 mounting dimensions and your FA/FB or LB bracket fit before ordering. Also note the fixed TPU bumpers only decelerate the piston at each end; they never hold a load, so add a rod lock or pilot check if position must be kept on air loss.
