This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACED50X45 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACED50X45 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 ACPD50X45
The AirTAC Airtac ACPD Double Rod Compact Cylinder ACPD50X45 is a double acting, double rod DIN-standard tight/compact air cylinder with a Ø50mm bore and 45mm stroke, 1/8" air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACED50X45 (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPD Double Rod Compact Cylinder ACPD50X45
Double acting with a rod leaving both covers, the ACPD50X45 pushes and pulls with the same 881.2 N at 0.5 MPa (1233.7 N at 0.7 MPa) because each stroke works on the rod-side area. The 50 mm bore drives a 16 mm through-rod over a 45 mm stroke at 30-500 mm/s, with a fixed TPU bumper at each end. This model is discontinued; the current-production successor is the ACED50X45 in the same bore, stroke and force class.
The hard-anodized aluminium body is an ISO 21287 short build, cutting roughly 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight jigs and guarding. The through-rod resists rotation and side load and gives a symmetric mount, and the back-end rod can carry a sensor flag. Air supply is 0.15-1.0 MPa (22-145 psi), filtered to 40 um, with a 1.5 MPa (215 psi) proof rating and -20 to +70 C operation. Plan on about 529 N of usable work at 0.5 MPa, which is roughly 54 kg of real vertical load.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACED50X45 (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 ACPD50X45 Is Used
Two-sided press fixture
The 881.2 N symmetric output lets one cylinder clamp a machined aluminium housing from both sides in a CNC jig, with the 45 mm stroke clearing part loading.
Packaging line pusher
A 50 mm bore at 30-500 mm/s kicks cartons between conveyor lanes, and the rear rod can drive a flag past a CMSE switch when the -S magnet is ordered.
Reciprocating guide carriage
The through-rod keeps a sliding guide plate square under side load in a small assembly station, with TPU bumpers decelerating each end of the 45 mm travel.
Replacing the Airtac ACPD Double Rod Compact Cylinder ACPD50X45 with the ACED50X45
Size both ways: a 40 mm bore gives 571.8 N at 0.5 MPa if the load is lighter, while a 63 mm bore raises it to 1458.1 N for heavier tooling. Ports are 1/8" on this bore, and the female rod thread is M10x1.5. Mounting brackets from the FA/FB flange, LB foot and CA/CB clevis family bolt to the ISO 21287 face. The optional -S magnet enables CMSE / DMSE switches; without it no sensor can be fitted. A plain double-rod cylinder drifts when air is lost, so add a rod lock or pilot check for held loads. Order the ACED50X45 as the drop-in replacement and confirm the ISO 21287 mounting dimensions before swapping.
Replacement checklist
- ✓ Current-production ACE → ACED50X45
- ✓ 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 ACPD50X45 FAQ
Because a rod exits both covers, output is equal both ways: 881.2 N at 0.5 MPa and 1233.7 N at 0.7 MPa, peaking at 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 runs 30-500 mm/s.
The model is discontinued; the current drop-in is the ACED50X45, which matches the same bore, stroke and force class - confirm the ISO 21287 mounting dimensions before swapping. For sensing, order the optional -S magnet version, which accepts CMSE or DMSE switches; the standard code has no magnet fitted.
