This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACED100X40B — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACED100X40B 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 ACPD100X40B
The AirTAC Airtac ACPD Double Rod Compact Cylinder ACPD100X40B is a double acting, double rod DIN-standard tight/compact air cylinder with a Ø100mm bore and 40mm stroke, 1/4" air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACED100X40B (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPD Double Rod Compact Cylinder ACPD100X40B
A double acting compact cylinder with a rod exiting BOTH covers, the ACPD100X40B pushes and pulls with identical force: 3681.6 N at 0.5 MPa and 5154.2 N at 0.7 MPa in each direction, because both strokes work on the rod-side area. The 100 mm bore drives a 25 mm hard-chrome S45C rod through a hard-anodized aluminium ISO 21287-style short body, with a fixed TPU bumper at each end and 1/4" ports. Speed range is 30-500 mm/s over 0.15-1.0 MPa (22-145 psi).
The through-rod resists rotation and side load and gives a symmetric mount, so the rear rod can carry a sensor flag or a second tooling plate while the front rod does the work. Its short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, which is why it fits deep inside press fixtures and gantries. Note this model is DISCONTINUED: the current-production drop-in is the ACED100X40 (swap the P for an E), same bore, stroke and force class - confirm the ISO 21287 mounting dimensions before swapping. Plan real work at roughly 2209 N (about 0.6 of the 0.5 MPa rating); vertically that is about 225 kg, or about 113 kg with a 2:1 margin.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACED100X40B (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 ACPD100X40B Is Used
Press fixture clamping
The 3681.6 N both-ways force and 40 mm stroke suit a stamping or riveting fixture where the rear rod carries a position flag while the front rod clamps the workpiece.
Gantry pick-and-place
A symmetric through-rod mount lets a 100 mm bore lift about 113 kg vertically with a 2:1 margin on a CNC tending gantry, with the short body fitting inside the Z-axis beam.
Bottle-line reject pusher
On a bottling conveyor, the 25 mm rod and fixed TPU bumpers give a stiff 40 mm kick to push off-spec containers at 30-500 mm/s without hammering the stops.
Replacing the Airtac ACPD Double Rod Compact Cylinder ACPD100X40B with the ACED100X40B
At 3681.6 N per side at 0.5 MPa, the 100 mm bore is the top of the ACPD range; if your job needs under 2356.2 N, the 80 mm bore saves space and air, and the 63 mm bore (1458.1 N) suits lighter clamping. The 40 mm stroke is well inside the 300 mm maximum standard stroke for this bore, so it is a catalog item, not a made-to-order length. This unit has a MALE rod thread (the B code) and PT ports; no magnet is fitted, so order the -S code if you later want CMSE / DMSE switches. A plain double-rod cylinder drifts when air is lost - add a rod lock or pilot check if the load must stay put. Since ACPD is discontinued, spec the ACED100X40 as the current replacement and verify the ISO 21287 mounting footprint.
Replacement checklist
- ✓ Current-production ACE → ACED100X40B
- ✓ 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 ACPD100X40B FAQ
Because a rod exits both covers, output is EQUAL both ways (rod-side area): 3681.6 N at 0.5 MPa and 5154.2 N at 0.7 MPa in each direction, 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, ports 1/4" PT, rod 25 mm with a male thread (B code).
Order the ACED100X40, the current ISO 21287 successor (swap the P for an E) in the same bore, stroke and force class; confirm the mounting dimensions before swapping since the ACP is DIN-standard. On either cylinder, position sensing needs the optional -S magnet code - without it no magnet is fitted and CMSE / DMSE switches cannot be mounted.
