This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACED63X55S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACED63X55S 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 ACPD63X55S
The AirTAC Airtac ACPD Double Rod Compact Cylinder ACPD63X55S is a double acting, double rod DIN-standard tight/compact air cylinder with a Ø63mm bore and 55mm stroke, 1/8" air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACED63X55S (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPD Double Rod Compact Cylinder ACPD63X55S
A double acting compact cylinder with a rod leaving both covers, the ACPD63X55S pushes and pulls with identical force: 1458.1 N at 0.5 MPa and 2041.3 N at 0.7 MPa in each direction, because both strokes work on the rod-side area of the 63 mm bore. The through-rod resists rotation and side load, gives a symmetric mount, and the rear rod can carry a sensor flag, while fixed TPU bumpers decelerate the piston at each end. Speed range is 30-500 mm/s on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi).
The short ISO 21287-class body saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight welding jigs and press fixtures. For sizing, treat about 875 N (roughly 0.6 of the 0.5 MPa rating) as the usable working force, which lifts about 74 kg vertically with a 2:1 margin. 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 sensing. Note that this model is discontinued: the current-production successor is the ACED63X55, and buyers should confirm the ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACED63X55S (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 (Ø63mm)
| Pressure | Force (both ways) |
|---|---|
| 0.5 MPa | 1458 N |
| 0.7 MPa | 2041 N |
| Max (@1.0 MPa) | 297 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 ACPD63X55S Is Used
Symmetric press fixture
The equal 1458.1 N force in both directions suits a punch-and-eject station on an aluminium extrusion line, where the through-rod ejects the part on the return stroke with the same rating as the clamp stroke.
Rotary indexing table drive
A rack pinion indexed by the front rod while the rear rod carries a CMSE switch flag, using the 55 mm stroke to rotate a machining pallet between two drilling positions at up to 500 mm/s.
Guided lift mast carriage
The 16 mm through-rod on both covers stabilises a vertical lift carriage on a small packaging machine, raising about 74 kg of tooling with a 2:1 margin at 0.5 MPa.
Replacing the Airtac ACPD Double Rod Compact Cylinder ACPD63X55S with the ACED63X55S
At 55 mm stroke this sits well inside the 250 mm maximum standard stroke for the 63 mm bore, so it is a catalogue item, not a made-to-order length. If 1458.1 N per direction is more than the job needs, the ACPD50 at 881.2 N both ways at 0.5 MPa is the step down; for heavier clamping the ACPD80 delivers 2356.2 N. Mount with FA/FB flange or LB foot brackets from the ISO 21287 family, and keep the -S magnet matched to CMSE / DMSE switches. Since the piston drifts when air is lost, add a rod lock or pilot check valve for a held load. Order the ACED63X55 as the current replacement for this discontinued model.
Replacement checklist
- ✓ Current-production ACE → ACED63X55S
- ✓ 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 ACPD63X55S FAQ
Because it is a double-rod cylinder, force is identical both ways: 1458.1 N at 0.5 MPa and 2041.3 N at 0.7 MPa per direction, with a maximum of 297.4 kgf at 1.0 MPa. Operating pressure is 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), and the 1/8" port serves both chambers.
The hard-anodized aluminium body follows the short ISO 21287 compact format, cutting about 50% of the mounting length of an ISO 15552 profile cylinder, with FA/FB flange and LB foot options. The -S code on this model means the magnet is fitted, so CMSE or DMSE switches can be mounted for position feedback. The model is discontinued; the ACED63X55 is the current drop-in, so confirm the ISO 21287 mounting dimensions before ordering.
