This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACED50X100S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACED50X100S 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 ACPD50X100S
The AirTAC Airtac ACPD Double Rod Compact Cylinder ACPD50X100S is a double acting, double rod DIN-standard tight/compact air cylinder with a Ø50mm bore and 100mm stroke, 1/8" air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACED50X100S (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPD Double Rod Compact Cylinder ACPD50X100S
A double acting, double-rod compact cylinder built to the DIN-standard ACP layout, the ACPD50X100S pushes a 50 mm piston through a 100 mm stroke with a rod leaving both covers. Because each side works on the rod-side area, output is identical in either direction: 881.2 N at 0.5 MPa and 1233.7 N at 0.7 MPa. The through-rod resists rotation and side load, and the rear rod can carry a sensor flag, while fixed TPU bumpers pad both ends of travel at speeds of 30-500 mm/s.
In practice that 881.2 N rating translates to roughly 529 N of usable work at 0.5 MPa, which is about 45 kg of vertical lift with a 2:1 margin. The hard-anodized aluminium body with an S45C hard-chrome rod saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight jigs and gantries. This model carries the optional -S magnet, so CMSE or DMSE switches can be mounted directly. Note: the ACPD family is discontinued; the current-production drop-in is the ISO 21287 ACED50X100, so confirm mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACED50X100S (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 ACPD50X100S Is Used
Reciprocating transfer carriage
The through-rod drives a pallet shuttle on a packaging line, pushing and pulling with equal 881.2 N force at 0.5 MPa so the return stroke needs no derating.
Position-flagged gate on a filler
With the -S magnet fitted, CMSE or DMSE switches read end positions on a bottling gate, while the rear rod carries a second flag for mid-stroke confirmation.
Symmetric press fixture
A bench fixture for crimping aluminum terminals uses the dual rods to guide the tool square, applying about 529 N of practical working force at 0.5 MPa.
Replacing the Airtac ACPD Double Rod Compact Cylinder ACPD50X100S with the ACED50X100S
At 50 mm bore this unit delivers 881.2 N both ways at 0.5 MPa. If your load needs less, the 40 mm bore gives 571.8 N; if you need more reach, step up to the 63 mm bore at 1458.1 N. Remember that a plain double-rod cylinder drifts when air is lost, so add a rod lock or pilot check for held loads. FA/FB flange, LB foot, CA/CB clevis, CR, SDB pivot and FTC brackets bolt to the mounting face, and the -S magnet on this model accepts CMSE / DMSE switches. For new projects, order the ACED50X100 instead, as ACPD is discontinued.
Replacement checklist
- ✓ Current-production ACE → ACED50X100S
- ✓ 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 ACPD50X100S 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, both measured on the rod-side area. At 1.0 MPa the maximum is 179.7 kgf. Operating pressure is 0.15-1.0 MPa (22-145 psi) with a 1.5 MPa (215 psi) proof pressure, and speed runs 30-500 mm/s.
The hard-anodized aluminium body follows the short ISO 21287-class layout, cutting roughly 50% of the mounting length of an ISO 15552 profile cylinder, with a fixed TPU bumper at each end and a female M10x1.5 rod thread. The ACPD is no longer produced; the ACED50X100 is the current drop-in successor in the same bore, stroke and force class, so verify the ISO 21287 mounting dimensions before converting.
