This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACED50X300S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACED50X300S 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 ACPD50X300S
The AirTAC Airtac ACPD Double Rod Compact Cylinder ACPD50X300S is a double acting, double rod DIN-standard tight/compact air cylinder with a Ø50mm bore and 300mm stroke, 1/8" air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACED50X300S (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPD Double Rod Compact Cylinder ACPD50X300S
A double acting compact cylinder with a rod leaving both covers, the ACPD50X300S pushes and pulls with identical output because each stroke works on the rod-side area: 881.2 N at 0.5 MPa and 1233.7 N at 0.7 MPa in either direction. Its 300 mm stroke is longer than the 250 mm standard maximum for a 50 mm bore, so it is a made-to-order build. This model is discontinued; the current-production drop-in is ACED50X300, so confirm ISO 21287 mounting dimensions before swapping.
The through-rod resists rotation and side load and gives a symmetric mount, and the rear rod can carry a sensor flag. The hard-anodized aluminium body with an S45C hard-chrome rod runs on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi), 30-500 mm/s, with a fixed TPU bumper at both ends. The short ISO 21287 body saves about 50% of the mounting length of an ISO 15552 profile cylinder. For sizing, expect roughly 529 N of usable work at 0.5 MPa, which lifts about 45 kg vertically with a 2:1 margin. The S code in this model means the optional -S magnet is fitted, so CMSE / DMSE switches can be mounted.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACED50X300S (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 ACPD50X300S Is Used
Reciprocating paint-line carrier
The through-rod drives a carriage back and forth over a 300 mm path, delivering 881.2 N in each direction so the return stroke accelerates the load as hard as the forward stroke.
Gantry position feedback on a PCB line
With the -S magnet fitted, CMSE or DMSE switches on the body report end positions, while the rear rod carries a flag for an external proximity sensor on the gantry.
Symmetric press fixture for gasket bonding
Two rods let the fixture clamp from both faces with the same 1233.7 N at 0.7 MPa, keeping the bond line even on rubber-to-metal gasket assemblies.
Replacing the Airtac ACPD Double Rod Compact Cylinder ACPD50X300S with the ACED50X300S
At 881.2 N both ways at 0.5 MPa, this 50 mm double-rod unit sits between the 40 mm bore (571.8 N) and the 63 mm bore (1458.1 N) in the same family. Choose it when equal force in extend and retract matters, such as a reciprocating carrier or a symmetric clamp. Note that a plain double-rod cylinder drifts when air is lost, so add a rod lock or pilot check for a held load. The 300 mm stroke is non-standard for this bore and is made to order. FA/FB flange or LB foot mounts bolt to the ISO 21287 face. Since ACPD is discontinued, order ACED50X300 as the current replacement and verify the mounting dimensions.
Replacement checklist
- ✓ Current-production ACE → ACED50X300S
- ✓ 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 ACPD50X300S FAQ
Yes. Because a rod exits both covers, both strokes use the rod-side area, so force is equal both ways: 881.2 N at 0.5 MPa and 1233.7 N at 0.7 MPa, with a maximum of 179.7 kgf at 1.0 MPa. Operating range is 0.15-1.0 MPa (22-145 psi) with a 1.5 MPa (215 psi) proof pressure, and speed is 30-500 mm/s.
Order ACED50X300, the ISO 21287 successor made by swapping the P for an E. It matches the same 50 mm bore, 300 mm stroke and force class, and accepts the FA/FB flange and LB foot mounting family. Because the ACP is DIN-standard, confirm the ISO 21287 mounting dimensions before swapping. This unit also carries the optional -S magnet for CMSE / DMSE switches, and its 300 mm stroke is a made-to-order length above the 250 mm standard maximum.
