This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACED50X250 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACED50X250 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 ACPD50X250
The AirTAC Airtac ACPD Double Rod Compact Cylinder ACPD50X250 is a double acting, double rod DIN-standard tight/compact air cylinder with a Ø50mm bore and 250mm stroke, 1/8" air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACED50X250 (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPD Double Rod Compact Cylinder ACPD50X250
A double acting compact cylinder with a rod leaving both covers, the ACPD50X250 delivers 881.2 N in each direction at 0.5 MPa because both strokes work on the rod-side area. The 50 mm bore pushes 1233.7 N at 0.7 MPa either way, and the through-rod resists rotation and side load while the rear rod can carry a sensor flag. Running on 0.15-1.0 MPa (22-145 psi) at 30-500 mm/s, it suits gantries and pick-and-place slides where a symmetric mount matters.
The short ISO 21287-class body saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight machine frames. In practice the 881.2 N rating supports about 45 kg of vertical lifting once you keep a 2:1 margin, enough to raise a 40 kg pallet fixture with room to spare. A fixed TPU bumper sits at each end, and the optional -S magnet enables CMSE / DMSE switches. This model is discontinued; the current-production replacement is ACED50X250, so confirm ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACED50X250 (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 ACPD50X250 Is Used
Reciprocating conveyor pusher
The rear rod drives a return flag while the front rod pushes cartons off a 600 mm belt, with 881.2 N per side handling a 40 kg product stream at 0.5 MPa.
Gantry Z-axis part lift
A through-rod mount on a CNC tending gantry lifts about 45 kg of aluminum housings vertically with a 2:1 margin, the symmetric rods keeping the gripper plate level.
Case clamp on a carton sealer
Both rods clamp a 400 mm shipping case square against the sealing head, the through-rod resisting side load as the flap folder cycles at 300 mm/s.
Replacing the Airtac ACPD Double Rod Compact Cylinder ACPD50X250 with the ACED50X250
At 881.2 N per side, this 50 mm bore sits between the 40 mm bore (571.8 N) and the 63 mm bore (1458.1 N) at 0.5 MPa. If your fixture needs under 550 N of usable thrust, the 40 mm saves space; if you are lifting near the 45 kg vertical mark with a 2:1 margin, stay at 50 mm or step up. Remember a plain double-rod cylinder drifts when air is lost, so add a rod lock or pilot check for held loads. FA/FB flange and LB foot mountings bolt to the ISO 21287 face, and the optional -S magnet pairs with CMSE / DMSE switches. Order ACED50X250 as the current drop-in and verify the mounting dimensions against your fixture.
Replacement checklist
- ✓ Current-production ACE → ACED50X250
- ✓ 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 ACPD50X250 FAQ
Yes, both directions are equal because the double-rod design works on the rod-side area at each end. At 0.5 MPa you get 881.2 N per stroke, at 0.7 MPa you get 1233.7 N per stroke, and the maximum at 1.0 MPa is 179.7 kgf. Operating range is 0.15-1.0 MPa (22-145 psi) with a 1.5 MPa (215 psi) proof pressure, speed 30-500 mm/s.
Order ACED50X250, the ISO 21287 successor made by swapping the P for an E. It matches the same 50 mm bore, 250 mm stroke and force class with a matching short body and mounting family. Since the ACP is DIN-standard, confirm the ISO 21287 mounting dimensions against your fixture before the swap. If you need position switches, remember the magnet is the optional -S code paired with CMSE / DMSE sensors.
