This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACED63X40SB, 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 ACPD63X40SB
The AirTAC ACPD Double Rod Compact Cylinder ACPD63X40SB is a double acting, double rod DIN-standard tight/compact air cylinder with a Ø63mm bore and 40mm stroke, 1/8" air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACED63X40SB (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPD Double Rod Compact Cylinder ACPD63X40SB
A double acting compact cylinder with a rod through both covers, the ACPD63X40SB delivers 1458.1 N at 0.5 MPa in either direction because both strokes work on the rod-side area. The 63 mm bore pushes 2041.3 N at 0.7 MPa, and the through-rod resists rotation and side load while the rear rod can carry a sensor flag. This model carries the optional -S magnet, so CMSE / DMSE reed or solid-state switches mount directly on the body.
The hard-anodized aluminium body follows the ISO 21287 short format, saving roughly 50% of the mounting length of an ISO 15552 profile cylinder, which suits tight jigs and gantries. A fixed TPU bumper sits at each end and the male rod thread (B code) with 1/8" PT ports keeps plumbing simple. Note that this ACPD is discontinued: the current direct is ACED63X40, so confirm ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACED63X40SB (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 (Ø63mm)
| Pressure | Force (both ways) |
|---|---|
| 0.5 MPa | 1458 N |
| 0.7 MPa | 2041 N |
| Max (@1.0 MPa) | 297 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 ACPD63X40SB Is Used
Reciprocating conveyor pushers
The through-rod gives an identical 1458.1 N stroke in both directions, ideal for pushing cartons off a line and returning a guide rail without recalculating pull force.
Symmetric clamp fixtures on CNC fixtures
A rod on each cover lets one piston clamp a workpiece while the rear rod drives a limit flag, keeping the 63 mm bore fixture compact inside the guard.
Pallet-stacker load centering
With about 875 N of practical force at 0.5 MPa, the cylinder centers pallets in narrow AGV bays where the short ISO 21287 body must fit between frame rails.
Replacing the Airtac ACPD Double Rod Compact Cylinder ACPD63X40SB with the ACED63X40SB
At 63 mm bore you sit between the 50 mm size (881.2 N at 0.5 MPa) and the 80 mm size (2356.2 N at 0.5 MPa), so pick 63 mm when 881 N falls short but 80 mm is oversized. The 40 mm stroke is well inside the 250 mm maximum standard stroke for this bore. If a load must stay put when air is lost, add a rod lock or pilot check, since a plain double-rod cylinder drifts. FA/FB flange and LB foot mounts bolt to the ISO 21287 face, and the -S magnet on this unit accepts CMSE / DMSE switches. For new projects, order the ACED63X40 instead.
Replacement checklist
- ✓ Current-production ACE → ACED63X40SB
- ✓ 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 ACPD63X40SB FAQ
Because the rod exits both covers, force is equal both ways: 1458.1 N at 0.5 MPa and 2041.3 N at 0.7 MPa, with a maximum of 297.4 kgf at 1.0 MPa. Operating pressure is 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), speed 30-500 mm/s, and the 40 mm stroke is a standard stroke for the 63 mm bore.
No. The ACPD family is discontinued. The current-production direct is ACED63X40, the ISO 21287 ACE in the same bore, stroke and force class. Before swapping, confirm the ISO 21287 mounting dimensions, since the ACP was built to a DIN-standard footprint. The fixed TPU bumpers at both ends carry over in concept, and the -S magnet option for CMSE / DMSE switches remains available on the ACE.
