This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACED40X275B — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACED40X275B 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 ACPD40X275B
The AirTAC Airtac ACPD Double Rod Compact Cylinder ACPD40X275B is a double acting, double rod DIN-standard tight/compact air cylinder with a Ø40mm bore and 275mm stroke, 1/8" air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACED40X275B (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPD Double Rod Compact Cylinder ACPD40X275B
This double acting compact cylinder pushes a 12 mm rod out of BOTH covers, so the 40 mm bore delivers the same 571.8 N at 0.5 MPa (800.5 N at 0.7 MPa) whether it extends or retracts. The 275 mm stroke is longer than the 200 mm standard limit for this bore, so it is a made-to-order build. The through-rod resists rotation and side load and gives a symmetric mount, with a fixed TPU bumper at each end and speeds of 30-500 mm/s.
The hard-anodized aluminium body follows the ISO 21287 short format, cutting about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight gantries and guarding. At 0.5 MPa, plan for roughly 343 N (about 35 kg) of usable work, or expect it to lift about 29 kg vertically with a 2:1 margin. Note: this model is discontinued - the current-production drop-in is ACED40X275, so confirm ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACED40X275B (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 ACPD40X275B Is Used
Reciprocating transfer arm
The through-rod carries a workpiece gripper on the front rod and a counterweight or sensor flag on the rear rod, moving parts 275 mm between a pick fixture and a placement nest on an electronics assembly line.
Symmetric clamp-and-eject station
Equal 571.8 N force in both directions lets one cylinder clamp a machined housing and then eject it from the same station on a CNC pallet changer, with the male thread taking an I/Y knuckle.
Conveyor pusher with rear flag
The back-end rod drives a CMSE or DMSE switch flag (when the optional -S magnet is ordered) to confirm stroke completion while the front rod pushes cartons across a packaging conveyor.
Replacing the Airtac ACPD Double Rod Compact Cylinder ACPD40X275B with the ACED40X275B
Size around the rod-side force: 571.8 N at 0.5 MPa both ways. A 32 mm bore gives 345.6 N if the load is lighter; step to 50 mm for 881.2 N. Because a plain double-rod cylinder drifts when air is lost, add a rod lock or pilot check for held loads. The male rod thread (B code) suits I/Y knuckles, and FA/FB flange or LB foot mounts bolt to the ISO 21287 face. The 275 mm stroke exceeds the 200 mm standard for bore 40, so it is made to order. This model is discontinued - order ACED40X275 instead and verify mounting dimensions.
Replacement checklist
- ✓ Current-production ACE → ACED40X275B
- ✓ 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 ACPD40X275B FAQ
Because a rod exits both covers, output is equal both ways: 571.8 N at 0.5 MPa and 800.5 N at 0.7 MPa, using the rod-side area. Peak force at 1.0 MPa is 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, with a fixed TPU bumper at each end. The 275 mm stroke is a non-standard, made-to-order length for this 40 mm bore.
This model is discontinued. The current-production drop-in is ACED40X275 - swap the P for an E - which matches the same bore, stroke and force class in the ISO 21287 short-body format; confirm the mounting dimensions before swapping since the ACP is DIN-standard. For sensing, the magnet is the optional -S code: order ACPD40X275BS to enable CMSE or DMSE reed or solid-state switches. Without -S there is no magnet and no switch can be mounted.
