This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACED50X275 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACED50X275 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 ACPD50X275
The AirTAC Airtac ACPD Double Rod Compact Cylinder ACPD50X275 is a double acting, double rod DIN-standard tight/compact air cylinder with a Ø50mm bore and 275mm stroke, 1/8" air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACED50X275 (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPD Double Rod Compact Cylinder ACPD50X275
A double acting, double-rod compact cylinder built to the DIN-standard ACP layout, the ACPD50X275 pushes a 16 mm rod out of BOTH covers, so every stroke delivers the same 881.2 N at 0.5 MPa (1233.7 N at 0.7 MPa) regardless of direction. The 50 mm bore runs on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi), proof tested to 1.5 MPa (215 psi), and travels at 30-500 mm/s. Its 275 mm stroke is longer than the 250 mm standard maximum for this bore, so it is a made-to-order build. Note: this model is discontinued; the current-production successor is ACED50X275.
The short ISO 21287-class body saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, which is why it slots into long-stroke gantries and sliding guards that a full-length body cannot fit. The through-rod resists rotation and side load and gives a symmetric mount, and the rear rod can carry a sensor flag. Fixed TPU bumpers sit at both ends, and the hard-anodized aluminium body pairs with an S45C hard-chrome rod. For planning: at 0.5 MPa the rod-side output of 881.2 N works out to about 90 kgf, so budget roughly 45 kg of vertical lift with a 2:1 margin, or about 529 N of usable push at a 60% duty figure. Magnet is not fitted on this code; the optional -S build adds one for CMSE / DMSE switches.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACED50X275 (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 (Ø50mm)
| Pressure | Force (both ways) |
|---|---|
| 0.5 MPa | 881 N |
| 0.7 MPa | 1234 N |
| Max (@1.0 MPa) | 180 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 ACPD50X275 Is Used
Reciprocating transfer carriage
The rear rod drives a return flag on a 275 mm shuttle between two pallet stops, with 881.2 N available in both travel directions at 0.5 MPa.
Lift-assist press station
A 45 kg fixture plate is raised and lowered on the through-rod with a 2:1 vertical margin, the symmetric rod keeping the plate level without a guide arm.
Conveyor pusher gate
The front rod swings a deflecting gate across a packaging line while the back rod carries a CMSE switch flag for gate-position feedback on -S builds.
Replacing the Airtac ACPD Double Rod Compact Cylinder ACPD50X275 with the ACED50X275
At 50 mm bore the through-rod gives 881.2 N in each direction at 0.5 MPa; step down to ACPD40 (571.8 N) for lighter clamping or up to ACPD63 (1458.1 N) when the load grows. The 275 mm stroke exceeds the 250 mm standard ceiling for this bore, so order it as a non-standard made-to-order unit. Remember that a plain double-rod cylinder 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 ACPD is discontinued, spec ACED50X275 as the drop-in and confirm the ISO 21287 mounting dimensions before swapping.
Replacement checklist
- ✓ Current-production ACE → ACED50X275
- ✓ 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 ACPD50X275 FAQ
Yes. Because a rod exits both covers, both strokes use the rod-side area: 881.2 N at 0.5 MPa and 1233.7 N at 0.7 MPa, equal push and pull. Peak output at 1.0 MPa is 179.7 kgf. Operating range is 0.15-1.0 MPa (22-145 psi) with 1.5 MPa (215 psi) proof pressure, speed 30-500 mm/s, and the 275 mm stroke is a made-to-order length above the 250 mm standard maximum.
Order ACED50X275, the current ISO 21287 compact cylinder that succeeds the ACP family (swap the P for an E). It matches the same 50 mm bore, 275 mm stroke class and force output, and accepts FA/FB flange, LB foot, CA/CB clevis, CR, SDB pivot and FTC brackets plus I/Y rod knuckles. Confirm the ISO 21287 mounting dimensions against your fixture before swapping, since the ACP was built to a DIN-standard footprint.
