This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACED100X20S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACED100X20S 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 ACPD100X20S
The AirTAC Airtac ACPD Double Rod Compact Cylinder ACPD100X20S is a double acting, double rod DIN-standard tight/compact air cylinder with a Ø100mm bore and 20mm stroke, 1/4" air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACED100X20S (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPD Double Rod Compact Cylinder ACPD100X20S
This is a double acting, double-rod compact cylinder built to the DIN-standard ACP pattern: a 100 mm bore pushes a 25 mm hard-chrome S45C rod out of BOTH covers, so the 20 mm stroke delivers the same 3681.6 N at 0.5 MPa (5154.2 N at 0.7 MPa) whether it extends or retracts. The through-rod resists rotation and side load, gives a symmetric mount, and the rear rod can carry a sensor flag. A fixed TPU bumper sits at each end, and speed runs 30-500 mm/s on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi).
The short ISO 21287-class body saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into dense press fixtures and gantries. This model carries the optional -S magnet, so CMSE or DMSE reed and solid-state switches can be clamped on for end-of-stroke detection. Note that it is discontinued: the current-production drop-in is the ACED100X20, and buyers should confirm the ISO 21287 mounting dimensions before swapping. With no air applied the piston drifts freely, so a rod lock or pilot check is needed to hold a load.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACED100X20S (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 (Ø100mm)
| Pressure | Force (both ways) |
|---|---|
| 0.5 MPa | 3682 N |
| 0.7 MPa | 5154 N |
| Max (@1.0 MPa) | 751 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 ACPD100X20S Is Used
Short-stroke press fixture
A 20 mm stroke with 3681.6 N at 0.5 MPa both ways suits a compact stamping or marking head on an aluminium jig, where the through-rod keeps the tooling square under side load.
Symmetric push-pull transfer
Because the rod-side area works on both strokes, one cylinder can clamp a panel on extension and release it on retraction with identical 5154.2 N force at 0.7 MPa - useful in automotive weld-cell fixtures.
Position-flagged gantry stop
The -S magnet lets CMSE or DMSE switches report end of stroke on a pallet-stop or elevator gate, while the rear rod carries a second flag for redundant confirmation.
Replacing the Airtac ACPD Double Rod Compact Cylinder ACPD100X20S with the ACED100X20S
At 100 mm bore this is the top of the ACPD range: 3681.6 N at 0.5 MPa in both directions, with 1/4" ports and an M16x1.5 female rod thread. In practice, plan on about 2209 N (roughly 225 kgf) of real work at 0.5 MPa, and for vertical lifting count on about 187 kg with a 2:1 margin. If your load needs less than 1458 N at 0.5 MPa, the 63 mm bore does the job with a smaller envelope; if you need more than 3681 N, no larger ACPD bore exists, so step up to a bigger frame. The 20 mm stroke is well inside the 300 mm maximum standard stroke for this bore. Mount with FA/FB flange or LB foot brackets, and remember this model is discontinued - order the ACED100X20 and verify the ISO 21287 footprint first.
Replacement checklist
- ✓ Current-production ACE → ACED100X20S
- ✓ 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 ACPD100X20S FAQ
Yes - the double-rod design means both strokes use the rod-side area, so force is equal extending and retracting: 3681.6 N at 0.5 MPa and 5154.2 N at 0.7 MPa, with a maximum of 750.8 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 1/4" port size depends only on the 100 mm bore.
Order the ACED100X20, the ISO 21287 successor made by swapping the P for an E. It matches the same 100 mm bore, 20 mm stroke and force class with a short compact body, but because the ACP was DIN-standard you should confirm the ISO 21287 mounting dimensions before swapping. The -S magnet on this model carries over as an option on the ACED, and CMSE / DMSE switches still work for position sensing.
