This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACED50X160S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACED50X160S 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 ACPD50X160S
The AirTAC Airtac ACPD Double Rod Compact Cylinder ACPD50X160S is a double acting, double rod DIN-standard tight/compact air cylinder with a Ø50mm bore and 160mm stroke, 1/8" air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACED50X160S (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPD Double Rod Compact Cylinder ACPD50X160S
The ACPD50X160S is a double acting, double-rod compact cylinder in the discontinued AirTAC ACP family. A 16 mm rod exits both covers of the hard-anodized aluminium body, so the 50 mm bore delivers an equal 881.2 N at 0.5 MPa (1233.7 N at 0.7 MPa) in each direction - there is no push/pull imbalance because both strokes work on the rod-side area. The through-rod resists rotation and side load, and the free back-end rod can carry a sensor flag or a second tooling plate.
This model carries the optional -S magnet, so CMSE or DMSE reed and solid-state switches can be clipped straight onto the body for end-of-stroke detection. The short ISO 21287-class body saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, which is why it suits tight jigs and gantries. At 0.5 MPa the usable working force is about 529 N, and the rod lifts roughly 45 kg vertically with a 2:1 margin - enough for a loaded aluminium fixture or a small pallet. Note that this model is discontinued; the current-production drop-in is the ACED50X160, so confirm ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACED50X160S (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 ACPD50X160S Is Used
Reciprocating transfer arm
The through-rod drives a slide both ways with equal 881.2 N force, and the back rod carries a CMSE switch flag for mid-travel sensing on a 160 mm shuttle stroke.
Clamping fixture with rear tooling
Mount a clamp pad on the front rod and a support or second pad on the rear rod; the symmetric mount resists rotation in a machining jig at about 529 N of usable force.
Vertical lift-and-lower station
With a 2:1 margin the rod lifts about 45 kg vertically - a loaded electronics tray or small die - while the TPU bumpers soften both ends of the 160 mm travel.
Replacing the Airtac ACPD Double Rod Compact Cylinder ACPD50X160S with the ACED50X160S
Size both ways: the 40 mm bore gives 571.8 N at 0.5 MPa if your load is lighter, while the 63 mm bore reaches 1458.1 N if you need more headroom. The 160 mm stroke sits well inside the 250 mm standard limit for bore 50, so no made-to-order build is required. A plain double-rod cylinder drifts when air is lost - add a rod lock or pilot check valve if the load must stay put. FA/FB flange or LB foot mounts bolt to the ISO 21287 face, and the -S magnet on this unit accepts CMSE / DMSE switches. Order the ACED50X160 as the current replacement.
Replacement checklist
- ✓ Current-production ACE → ACED50X160S
- ✓ 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 ACPD50X160S FAQ
Because a rod exits both covers, 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), speed 30-500 mm/s, and the 16 mm rod ends in a female M10x1.5 thread. The 1/8" port depends only on the 50 mm bore.
The short ISO 21287-class body saves about 50% of the mounting length of an ISO 15552 profile cylinder, with a fixed TPU bumper at each end and FA/FB flange or LB foot options. The ACPD family is discontinued; the ACED50X160 is the current-production drop-in with the same bore, stroke and force class - confirm the ISO 21287 mounting dimensions before you swap.
