This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACED50X90 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACED50X90 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 ACPD50X90
The AirTAC Airtac ACPD Double Rod Compact Cylinder ACPD50X90 is a double acting, double rod DIN-standard tight/compact air cylinder with a Ø50mm bore and 90mm stroke, 1/8" air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACED50X90 (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPD Double Rod Compact Cylinder ACPD50X90
A double acting, double-rod compact cylinder built to the DIN-standard ACP format, the ACPD50X90 pushes a 16 mm rod out of both covers on a 90 mm stroke. Because each side works on the rod-side area, it delivers an identical 881.2 N at 0.5 MPa in either direction, rising to 1233.7 N at 0.7 MPa. The hard-anodized aluminium body keeps the mounting length roughly half that of an ISO 15552 profile cylinder, so it slots into tight fixtures and guarding.
The through-rod resists rotation and side load and gives a symmetric mount, with the rear rod free to carry a sensor flag on a jig or gantry. In practice, plan on about 529 N (roughly 54 kg) of real work at 0.5 MPa, which lifts about 45 kg vertically with a 2:1 margin. A fixed TPU bumper sits at each end, and the optional -S magnet enables CMSE / DMSE switches. Note: this model is discontinued; the current-production replacement is the ACED50X90.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACED50X90 (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 ACPD50X90 Is Used
Symmetric clamp fixture
The 881.2 N equal force in both directions lets one ACPD50X90 clamp and release a machined housing on a CNC fixture with identical grip either way.
Reciprocating transfer slide
A rod on each cover drives a pallet slide back and forth over a 90 mm stroke at 30-500 mm/s, with the rear rod carrying a flag for position switches.
Battery-lift test rig
With about 45 kg of vertical lift capacity at a 2:1 margin, the cylinder raises EV battery modules on an assembly-line endurance tester.
Replacing the Airtac ACPD Double Rod Compact Cylinder ACPD50X90 with the ACED50X90
At 881.2 N per side, bore 50 sits between the 63 mm ACPD (1458.1 N) and the 40 mm ACPD (571.8 N) at 0.5 MPa, so step up or down depending on your fixture budget. The 90 mm stroke is well inside the 250 mm standard limit for this bore. Remember the piston drifts when air is lost - add a rod lock or pilot check if the load must stay put. Order the -S code if you need CMSE / DMSE sensing, pick FA/FB flange or LB foot mounting, and specify the ACED50X90 for new projects after confirming ISO 21287 mounting dimensions.
Replacement checklist
- ✓ Current-production ACE → ACED50X90
- ✓ 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 ACPD50X90 FAQ
It is a double-rod cylinder, so force is equal in both directions: 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 pressure is 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), and speed range 30-500 mm/s.
The short ISO 21287-class body saves about 50% of the mounting length of an ISO 15552 profile cylinder, with FA/FB flange or LB foot mounting and a fixed TPU bumper at each end. The ACPD50X90 is discontinued; the ACED50X90 is the current drop-in successor in the same bore, stroke and force class - confirm the ISO 21287 mounting dimensions before swapping.
