This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACED40X90 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACED40X90 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 ACPD40X90
The AirTAC Airtac ACPD Double Rod Compact Cylinder ACPD40X90 is a double acting, double rod DIN-standard tight/compact air cylinder with a Ø40mm bore and 90mm stroke, 1/8" air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACED40X90 (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPD Double Rod Compact Cylinder ACPD40X90
A double acting compact cylinder with a rod leaving both covers, the ACPD40X90 delivers 571.8 N at 0.5 MPa and 800.5 N at 0.7 MPa in either direction, because both strokes work on the rod-side area. The through-rod resists rotation and side load, gives a symmetric mount, and the rear rod can carry a sensor flag. A fixed TPU bumper sits at each end, and speed runs 30-500 mm/s.
The hard-anodized aluminium body follows the ISO 21287 short format, cutting roughly 50% of the mounting length compared with an ISO 15552 profile cylinder, so it slots into tight gantries and guarding. At 0.5 MPa the usable vertical lift works out to about 58 kg, or roughly 29 kg if you keep a 2:1 margin. Note that this model is discontinued: the current-production drop-in is the ACED40X90, so confirm the ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACED40X90 (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 ACPD40X90 Is Used
CNC fixture clamping
The 571.8 N through-rod push clamps steel brackets in a machining fixture, with the rear rod driving a position flag for the PLC.
Reciprocating transfer slide
Equal 800.5 N force at 0.7 MPa in both directions suits a 90 mm shuttle stroke moving small castings between two stations.
Lift-and-present elevator
With about 58 kg of vertical lift at 0.5 MPa, the double rod raises a palletized tray in a packaging cell and keeps it guided.
Replacing the Airtac ACPD Double Rod Compact Cylinder ACPD40X90 with the ACED40X90
For a 90 mm stroke in the 40 mm class, this unit gives 571.8 N both ways at 0.5 MPa; plan on about 343 N of real work to keep margin. If your load needs less, the ACPD32X50-class bore offers 345.6 N at 0.5 MPa; if it needs more, step up to the 50 mm bore at 881.2 N. Remember the piston drifts when air is lost, so add a rod lock or pilot check for a held load. FA/FB flange or LB foot mounting bolts to the ISO 21287 face, and the optional -S magnet enables CMSE / DMSE switches. Since the ACPD is discontinued, order the ACED40X90 as the current replacement.
Replacement checklist
- ✓ Current-production ACE → ACED40X90
- ✓ 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 ACPD40X90 FAQ
It is a double-rod cylinder, so force is identical in both directions: 571.8 N at 0.5 MPa and 800.5 N at 0.7 MPa, with a maximum of 116.6 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 bore is 40 mm with a 12 mm rod and 1/8" ports.
The ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, with a fixed TPU bumper at each end and FA/FB flange or LB foot options. The ACPD40X90 itself is discontinued; the ACED40X90 is the current drop-in in the same bore, stroke and force class, so confirm the ISO 21287 mounting dimensions before you swap.
