This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACED100X325SB — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACED100X325SB 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 ACPD100X325SB
The AirTAC Airtac ACPD Double Rod Compact Cylinder ACPD100X325SB 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 ACED100X325SB (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPD Double Rod Compact Cylinder ACPD100X325SB
Double acting and double rod, the ACPD100X325SB pushes a rod out of BOTH covers of its hard-anodized aluminium body, so the 100 mm bore delivers the same 3681.6 N at 0.5 MPa (5154.2 N at 0.7 MPa) in each direction - both strokes work on the rod-side area. The 25 mm S45C hard-chrome through-rod resists rotation and side load and gives a symmetric mount, and the rear rod can carry a sensor flag. This unit carries the optional -S magnet, so CMSE / DMSE reed or solid-state switches mount directly on the body. Air supply is 0.15-1.0 MPa (22-145 psi), speed range 30-500 mm/s, with a fixed TPU bumper at each end.
The short ISO 21287-class body saves about 50% of the mounting length of an ISO 15552 profile cylinder, which is why this big bore still fits tight gantries and press fixtures. Practical sizing: at 0.5 MPa plan on roughly 2209 N of usable work (about 60% of the rating), which corresponds to lifting about 187 kg vertically with a 2:1 margin. Note the 325 mm stroke exceeds the 300 mm maximum standard stroke for bore 100, so it is made to order. This model is discontinued - the current-production replacement is the ACED100X325, a drop-in in the same bore, stroke and force class; confirm ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACED100X325SB (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 ACPD100X325SB Is Used
Heavy press fixture ejection
The 3681.6 N rod-side force in both directions ejects stamped steel brackets from a die, and the 325 mm made-to-order stroke clears a deep die set that a 300 mm standard stroke cannot.
Pallet stacker lift column
A through-rod on both ends of the 100 mm bore lifts about 187 kg of loaded pallet plates vertically with a 2:1 margin, the rear rod carrying a flag for a DMSE switch to confirm top of stroke.
Billet transfer on a forging line
Equal 5154.2 N at 0.7 MPa on push and pull swings a hot billet carrier back and forth, the symmetric double-rod mount resisting the side load of an off-center part.
Replacing the Airtac ACPD Double Rod Compact Cylinder ACPD100X325SB with the ACED100X325SB
At 100 mm bore this is the top of the ACPD range: 3681.6 N at 0.5 MPa both ways, versus 2356.2 N for the 80 mm bore below it. If your fixture needs less force, the 80 mm double-rod unit is the step down. The 325 mm stroke is non-standard (bore 100 standard tops out at 300 mm), so order it as a made-to-order build. The B code gives a male 25 mm rod thread and the port thread is PT (1/4" ports). Because a plain double-rod cylinder drifts when air is lost, add a rod lock or pilot check if the load must stay put. FA/FB flange and LB foot mountings suit this force class. Order the ACED100X325 instead - this ACPD is discontinued and the ACE is the current drop-in; verify ISO 21287 mounting dimensions first.
Replacement checklist
- ✓ Current-production ACE → ACED100X325SB
- ✓ 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 ACPD100X325SB FAQ
Yes - it is a double-rod cylinder, so a rod exits both covers and both strokes use the rod-side area of the 100 mm bore. Force is 3681.6 N at 0.5 MPa and 5154.2 N at 0.7 MPa, equal in both directions, with a maximum of 750.8 kgf at 1.0 MPa. Operating pressure is 0.15-1.0 MPa (22-145 psi), proof 1.5 MPa (215 psi), speed 30-500 mm/s, and the 325 mm stroke is a made-to-order build above the 300 mm standard maximum.
Order the ACED100X325, the current-production ISO 21287 ACE successor: swap the P for an E and you get the same 100 mm bore, 325 mm stroke and force class in a short compact body. Because the ACP is DIN-standard, confirm the ISO 21287 mounting dimensions and the FA/FB or LB mounting interfaces before swapping. This model also carries the -S magnet for CMSE / DMSE switches - check whether your replacement needs the magnet option ordered too.
