This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACED100X325B — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACED100X325B 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 ACPD100X325B
The AirTAC Airtac ACPD Double Rod Compact Cylinder ACPD100X325B is a double acting, double rod DIN-standard tight/compact air cylinder with a Ø100mm bore and 325mm stroke, 1/4" air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACED100X325B (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPD Double Rod Compact Cylinder ACPD100X325B
This is a double acting, double-rod compact cylinder in the discontinued AirTAC ACPD series: a 100 mm bore with a 25 mm rod leaving BOTH covers, so the through-rod gives equal force in each direction (3681.6 N at 0.5 MPa and 5154.2 N at 0.7 MPa, both ways) and a symmetric mount that resists rotation and side load. The 325 mm stroke is longer than the 300 mm standard maximum for this bore, so it is a made-to-order build. The hard-anodized aluminium body keeps the mounting length roughly 50% shorter than an ISO 15552 profile cylinder, which matters on long-stroke gantries and transfer frames where every millimetre of envelope counts.
In practice, plan on about 2209 N of usable push at 0.5 MPa (roughly 60% of the rating), which is about 188 kg of vertical lift with a 2:1 margin - enough to raise a loaded pallet fixture or a steel weldment. The 1/4" ports, fixed TPU bumpers at both ends and 30-500 mm/s speed range suit fast, long-travel strokes. Note this model is discontinued: the current-production drop-in is the ISO 21287 ACED100X325, so confirm the mounting dimensions before swapping. The optional -S magnet code enables CMSE / DMSE switches; without it no magnet is fitted.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACED100X325B (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 ACPD100X325B Is Used
Pallet-lift fixture on a packing line
With about 188 kg of vertical lift at a 2:1 margin from the 3681.6 N rating, the through-rod can raise a loaded pallet or tote stack between two guides, with the rear rod carrying a position flag.
Long-stroke steel weldment transfer
The 325 mm made-to-order stroke crosses a weld cell in one move, and the double rod resists the side load of an off-centre steel bracket without extra guides.
Gantry pusher over a wide conveyor
Equal 5154.2 N force in both directions at 0.7 MPa lets one cylinder eject and retract heavy carton stacks at full speed, with the short body fitting under low gantry beams.
Replacing the Airtac ACPD Double Rod Compact Cylinder ACPD100X325B with the ACED100X325B
At 100 mm bore this is the top of the ACPD range: 3681.6 N both ways at 0.5 MPa versus 2356.2 N for the 80 mm bore, so step up only if your load truly needs the extra 1300 N. If the job is lighter, the 80 mm size saves space and air. Because the piston drifts when air is lost, add a rod lock or pilot check valve for any held or vertical load. The B code gives a male rod thread (M16x1.5 on this bore) and PT ports; FA/FB flange or LB foot mounts bolt to the ISO 21287 face. Order the -S code if you need CMSE / DMSE switch positions. This model is discontinued - specify the ACED100X325 as the current replacement and verify its ISO 21287 mounting dimensions.
Replacement checklist
- ✓ Current-production ACE → ACED100X325B
- ✓ 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 ACPD100X325B FAQ
Both directions are identical because a rod exits each cover and both strokes use the rod-side area: 3681.6 N at 0.5 MPa, 5154.2 N at 0.7 MPa, and a maximum of 750.8 kgf at 1.0 MPa. Operating pressure is 0.15-1.0 MPa (22-145 psi) with 1.5 MPa (215 psi) proof pressure, air filtered to 40 um, speed 30-500 mm/s and -20 to +70 C.
Yes. The standard maximum for the 100 mm bore is 300 mm, so 325 mm is a made-to-order stroke - allow extra lead time and confirm the drawing. The ACPD series itself is discontinued; the current-production successor is the ISO 21287 ACED100X325, a drop-in in the same bore, stroke and force class. Check the ISO 21287 mounting dimensions before swapping, since the ACP is DIN-standard.
