This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACED50X150B — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACED50X150B 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 ACPD50X150B
The AirTAC Airtac ACPD Double Rod Compact Cylinder ACPD50X150B is a double acting, double rod DIN-standard tight/compact air cylinder with a Ø50mm bore and 150mm stroke, 1/8" air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACED50X150B (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPD Double Rod Compact Cylinder ACPD50X150B
A double acting compact cylinder with a rod leaving both covers, the ACPD50X150B pushes and pulls with identical force: 881.2 N at 0.5 MPa and 1233.7 N at 0.7 MPa in either direction, since both strokes work on the rod-side area. The 16 mm 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 stroke 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 an ISO 15552 profile cylinder would need, which matters in tight gantries and guarding. Practical sizing: keep real work near 529 N (about 60% of rating), which lifts roughly 45 kg vertically with a 2:1 margin. Note this model is discontinued - the current drop-in is the ACED50X150, so confirm ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACED50X150B (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 ACPD50X150B Is Used
Reciprocating conveyor pusher
The equal 881.2 N output in both directions lets one 150 mm stroke divert cartons on a packaging line without re-plumbing for a weaker return stroke.
Symmetric fixture clamp
A 16 mm through-rod on a CNC jig fixture keeps the clamp aligned under side load, with the rear rod doubling as a mount point for a position flag.
Pallet-stacker lift assist
With about 45 kg of vertical lift at a 2:1 margin, the cylinder raises small pallet components in warehouse handling rigs at up to 500 mm/s.
Replacing the Airtac ACPD Double Rod Compact Cylinder ACPD50X150B with the ACED50X150B
At 881.2 N per side, the 50 mm bore suits clamping and transfer duties in the 500-900 N band; step down to the 40 mm bore (571.8 N) for lighter jigs or up to the 63 mm bore (1458.1 N) when the load grows. The 150 mm stroke sits well inside the 250 mm standard limit for this bore. The B code gives a male M10x1.5 rod thread and the 1/8" port is PT as ordered. Without the -S code there is no magnet, so add it if CMSE or DMSE switches are planned. Since the ACPD is discontinued, order the ACED50X150 as the current-production equivalent and verify the ISO 21287 footprint. For loads that must stay put on air loss, add a rod lock or pilot check - the bumper never holds position.
Replacement checklist
- ✓ Current-production ACE → ACED50X150B
- ✓ 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 ACPD50X150B FAQ
Output is identical both ways because a rod exits each cover: 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. For sizing, treat about 529 N as usable work, which lifts roughly 45 kg vertically with a 2:1 margin. Operating range is 0.15-1.0 MPa (22-145 psi) and speed is 30-500 mm/s.
AirTAC retired the ACP family; the current-production replacement is the ACED50X150, an ISO 21287 compact cylinder in the same bore, stroke and force class. Confirm the ISO 21287 mounting dimensions against your fixture before swapping, since the ACP was built to the older DIN-standard format. FA/FB flange and LB foot brackets remain available for the ACE face.
