This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACED40X50 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACED40X50 in place of this model. 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 ACPD40X50
The AirTAC Airtac ACPD Double Rod Compact Cylinder ACPD40X50 is a double acting, double rod DIN-standard tight/compact air cylinder with a Ø40mm bore and 50mm stroke, 1/8" air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACED40X50 (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPD Double Rod Compact Cylinder ACPD40X50
A double acting compact cylinder with a rod leaving both covers, the ACPD40X50 pushes and pulls with the same 571.8 N at 0.5 MPa because each stroke works on the rod-side area. The 40 mm bore and 50 mm stroke suit tight pick-and-place heads, and the through-rod on the far end can carry a sensor flag or a second tool while resisting rotation and side load. Its hard-anodized aluminium body keeps the mounting length about 50% shorter than an ISO 15552 profile cylinder.
At 0.7 MPa the output rises to 800.5 N in either direction, with 116.6 kgf available at the full 1.0 MPa rating. As a planning figure, treat roughly 343 N as the usable push at 0.5 MPa, which lifts about 29 kg vertically with a 2:1 margin. A fixed TPU bumper sits at each end, the S45C hard-chrome rod runs 30-500 mm/s, and the magnet is not fitted on this code - order the -S variant if you need CMSE / DMSE switches. This model is discontinued; the current-production replacement is ACED40X50.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACED40X50 (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 (Ø40mm)
| Pressure | Force (both ways) |
|---|---|
| 0.5 MPa | 572 N |
| 0.7 MPa | 800 N |
| Max (@1.0 MPa) | 117 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 ACPD40X50 Is Used
CNC bar pusher
The 571.8 N symmetric output at 0.5 MPa ejects finished 40 mm bar stock from a lathe fixture, with the rear rod driving a chip-clearing flag.
Bottling line reject gate
A 50 mm stroke swings a reject flap on a filler conveyor; the through-rod resists the side load of the flap and keeps alignment over millions of cycles.
Carton clamp on a case packer
Equal force in both directions clamps and releases cartons at 0.7 MPa (800.5 N), with the fixed TPU bumpers absorbing end-of-stroke shock at 30-500 mm/s.
Replacing the Airtac ACPD Double Rod Compact Cylinder ACPD40X50 with the ACED40X50
Size between the 32 mm bore (345.6 N at 0.5 MPa) and the 50 mm bore (881.2 N at 0.5 MPa) depending on your fixture load; this 40 mm version delivers 571.8 N both ways at 0.5 MPa. Remember the piston drifts when air is lost - add a rod lock or pilot check if the load must stay put. FA/FB flange or LB foot mounts bolt to the ISO 21287 face, and the optional -S magnet enables CMSE / DMSE switch sensing. Since ACPD40X50 is discontinued, spec ACED40X50 as the drop-in and confirm the ISO 21287 mounting dimensions before swapping.
Replacement checklist
- ✓ Current-production ACE → ACED40X50
- ✓ 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 ACPD40X50 FAQ
It is a double-rod cylinder, so force is equal both ways: 571.8 N at 0.5 MPa and 800.5 N at 0.7 MPa, on the rod-side area. At the 1.0 MPa maximum it reaches 116.6 kgf. Operating range is 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), speed 30-500 mm/s, and the bore-40 port is 1/8" (PT thread).
The ACPD family is no longer produced; order ACED40X50, the ISO 21287 successor in the same bore, stroke and force class. Confirm the ISO 21287 mounting dimensions before the swap since the ACP is DIN-standard. For sensing, the magnet is the optional -S code - this plain model has no magnet, so specify ACPD40X50S (or the ACED equivalent) to run CMSE / DMSE switches.
