This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACED100X70B — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACED100X70B 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 ACPD100X70B
The AirTAC Airtac ACPD Double Rod Compact Cylinder ACPD100X70B is a double acting, double rod DIN-standard tight/compact air cylinder with a Ø100mm bore and 70mm stroke, 1/4" air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACED100X70B (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPD Double Rod Compact Cylinder ACPD100X70B
A double acting compact cylinder with a rod leaving both covers, the ACPD100X70B pushes with the same 3681.6 N at 0.5 MPa in each direction because both strokes work on the rod-side area of the 100 mm bore. The 25 mm through-rod resists rotation and side load, gives a symmetric mounting face, and lets the rear rod carry a sensor flag or a second tool. Its short ISO 21287 body saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into presses, gantries and guarding where a full-length body cannot go.
This 100 mm bore size is discontinued; the current-production drop-in is the ACED100X70, which matches the same bore, stroke and force class - confirm the ISO 21287 mounting dimensions before swapping. Plan on about 2209 N (roughly 225 kg of thrust) as the usable working force at 0.5 MPa, or about 187 kg of vertical lift with a 2:1 margin, instead of the full 3681.6 N rating. The male rod thread (B code) is M16x1.5, the air port is 1/4" PT, and a fixed TPU bumper sits at each end. No magnet is fitted on this code; order the -S version if you need CMSE or DMSE switches.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACED100X70B (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 ACPD100X70B Is Used
Heavy press-fit station
The symmetric 3681.6 N thrust at 0.5 MPa lets one cylinder press a bearing into a housing on the forward stroke and eject the finished part on the return, with the 70 mm stroke covering both moves.
Pallet-stacking lift assist
With about 187 kg of vertical lift capacity at a 2:1 margin, the double rod guides a palletizer pusher arm without a separate guide column, and the rear rod carries a flag for the CMSE switch when the -S magnet is ordered.
CNC fixture clamping
The short ISO 21287 body fits inside a machining-center fixture plate where an ISO 15552 profile cylinder would overhang, delivering 5154.2 N at 0.7 MPa to clamp steel blanks through the M16x1.5 male rod thread.
Replacing the Airtac ACPD Double Rod Compact Cylinder ACPD100X70B with the ACED100X70B
At 3681.6 N per side at 0.5 MPa, this bore suits heavy clamping and pressing where equal force in both directions matters. Step down to the 80 mm bore (2356.2 N) for lighter loads or up to a larger custom bore if you need more than 5154.2 N at 0.7 MPa. Remember the piston drifts when air is lost - add a rod lock or pilot check valve if the load must stay put. FA/FB flange and LB foot mountings bolt to the ISO 21287 face, and the optional -S magnet enables CMSE / DMSE switch position feedback. For new designs, specify the ACED100X70 instead, since this ACPD code is out of production.
Replacement checklist
- ✓ Current-production ACE → ACED100X70B
- ✓ 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 ACPD100X70B FAQ
Yes - the through-rod means both strokes use the rod-side area, so force is equal both ways: 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 range is 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), speed 30-500 mm/s, and the 70 mm stroke sits well inside the 300 mm maximum standard stroke for this bore.
The ACPD family is no longer in production; the current drop-in is the ACED100X70, which keeps the same 100 mm bore, 70 mm stroke and force class in the ISO 21287 short body - confirm the mounting dimensions before swapping, as the ACP was built to a DIN standard. On the ACPD itself, no magnet is fitted on this code; the optional -S version carries the magnet that allows CMSE or DMSE reed or solid-state switches.
