This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACED50X70 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACED50X70 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 ACPD50X70
The AirTAC Airtac ACPD Double Rod Compact Cylinder ACPD50X70 is a double acting, double rod DIN-standard tight/compact air cylinder with a Ø50mm bore and 70mm stroke, 1/8" air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACED50X70 (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPD Double Rod Compact Cylinder ACPD50X70
A double acting compact cylinder with a rod leaving both covers, the ACPD50X70 delivers 881.2 N in either direction at 0.5 MPa (1233.7 N at 0.7 MPa) because both strokes work on the rod-side area of its 50 mm bore. The through-rod resists rotation and side load, gives a symmetric mounting face, 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).
The hard-anodized aluminium body follows the ISO 21287 short format, cutting roughly 50% of the mounting length compared with an ISO 15552 profile cylinder, so it slots into tight jigs and gantries. Plan on about 529 N of real work at 0.5 MPa, which lifts roughly 45 kg vertically with a 2:1 margin. Note that this model is discontinued: the current-production drop-in is the ACED50X70, so confirm ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACED50X70 (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 ACPD50X70 Is Used
Two-sided fixture clamping
The 881.2 N equal force in both directions clamps and releases a machined aluminium housing in a CNC fixture from one compact body, no return spring needed.
Pusher with rear sensor flag
The back-end rod carries a flag plate so a proximity sensor confirms stroke position while the front rod pushes cartons off a packaging conveyor at 70 mm travel.
Symmetric slide drive
Driving a linear slide from the rod center keeps thrust balanced in both directions, ideal for a small assembly gantry where the short ISO 21287 body saves space.
Replacing the Airtac ACPD Double Rod Compact Cylinder ACPD50X70 with the ACED50X70
At 881.2 N per side, the 50 mm bore sits between the 40 mm (571.8 N) and 63 mm (1458.1 N) options at 0.5 MPa, so step down for lighter clamping or up for heavier presses. The through-rod suits symmetric tooling, and the female M10x1.5 rod thread takes standard I/Y knuckles. Mount with FA/FB flange or LB foot on the ISO 21287 face. If you need position feedback, order the -S variant with the optional magnet for CMSE / DMSE switches - this plain code has no magnet. Remember the piston drifts when air is lost, so add a rod lock or pilot check for held loads. Replacement: ACED50X70.
Replacement checklist
- ✓ Current-production ACE → ACED50X70
- ✓ 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 ACPD50X70 FAQ
Because a rod exits both covers, 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), proof pressure 1.5 MPa (215 psi), speed 30-500 mm/s, air filtered to 40 um.
The hard-anodized aluminium body follows the ISO 21287 short format, saving about 50% of the mounting length of an ISO 15552 profile cylinder, with a fixed TPU bumper at each end and FA/FB or LB mounting. The ACPD50X70 is discontinued; the current drop-in is the ACED50X70 in the same bore, stroke and force class - confirm ISO 21287 mounting dimensions before ordering.
