This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACED50X35S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACED50X35S 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 ACPD50X35S
The AirTAC Airtac ACPD Double Rod Compact Cylinder ACPD50X35S is a double acting, double rod DIN-standard tight/compact air cylinder with a Ø50mm bore and 35mm stroke, 1/8" air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACED50X35S (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPD Double Rod Compact Cylinder ACPD50X35S
A double acting compact cylinder with a rod through both covers, the ACPD50X35S pushes and pulls with identical force: 881.2 N at 0.5 MPa and 1233.7 N at 0.7 MPa in either direction, because both strokes work on the rod-side area. The 16 mm 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 over 0.15-1.0 MPa (22-145 psi) of clean, 40 um filtered air.
The hard-anodized aluminium body follows the short ISO 21287 format, cutting roughly 50% of the mounting length compared with an ISO 15552 profile cylinder, so it slots into tight fixtures and guarding. The -S code on this model means the magnet is fitted, so CMSE or DMSE reed and solid-state switches can be clipped on for end-of-stroke signals. Note the plain piston drifts when air is lost, so add a rod lock or pilot check if a load must be held. This model is discontinued; the current drop-in is the ACED50X35, and you should confirm the ISO 21287 mounting dimensions before swapping. As a sizing rule, expect about 529 N of usable work at 0.5 MPa, which lifts roughly 45 kg vertically with a 2:1 margin.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACED50X35S (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 ACPD50X35S Is Used
Symmetric press fixture
A bench-top crimping jig for terminal blocks uses the through-rod to clamp from both faces with the same 881.2 N force at 0.5 MPa, keeping the die centered without a guide.
Packaging pusher station
On a carton transfer line, the 35 mm stroke kicks boxes between conveyors at 30-500 mm/s, while CMSE switches on the -S magnet confirm each push completed.
Gantry pick point
A pick-and-place gantry uses the rear rod as a flag carrier for DMSE sensors and lifts about 45 kg vertically with a 2:1 margin, thanks to the 50 mm bore's rod-side output.
Replacing the Airtac ACPD Double Rod Compact Cylinder ACPD50X35S with the ACED50X35S
At 50 mm bore the double-rod output is 881.2 N at 0.5 MPa both ways. Step down to the 40 mm bore (571.8 N) for lighter clamping, or up to 63 mm (1458.1 N) if the job needs more muscle. The 35 mm stroke sits well inside the 250 mm maximum standard stroke for this bore, so it is a catalogue item, not a made-to-order build. Mount with FA/FB flange or LB foot brackets, and remember the magnet is only present because this unit carries the optional -S code. Since ACPD is discontinued, order the ACED50X35 as the current-production replacement and verify the ISO 21287 mounting dimensions against your fixture.
Replacement checklist
- ✓ Current-production ACE → ACED50X35S
- ✓ 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 ACPD50X35S FAQ
Because it is a double-rod cylinder, output is equal both ways: 881.2 N at 0.5 MPa and 1233.7 N at 0.7 MPa, with a maximum of about 179.7 kgf at 1.0 MPa. Both strokes use the rod-side area, so push never exceeds pull. Operating range is 0.15-1.0 MPa (22-145 psi) with 1.5 MPa (215 psi) proof pressure.
No, the ACPD family is discontinued. The current-production drop-in is the ACED50X35, the ISO 21287 successor in the same bore, stroke and force class. Confirm the ISO 21287 mounting dimensions before swapping, since the ACP follows the older DIN-standard compact format. The port is 1/8" and the female rod thread is M10x1.5.
