This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACED40X45B — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACED40X45B 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 ACPD40X45B
The AirTAC Airtac ACPD Double Rod Compact Cylinder ACPD40X45B is a double acting, double rod DIN-standard tight/compact air cylinder with a Ø40mm bore and 45mm stroke, 1/8" air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACED40X45B (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPD Double Rod Compact Cylinder ACPD40X45B
The ACPD40X45B is a double acting, double-rod compact cylinder in the discontinued AirTAC ACP family: a 40 mm bore with a 45 mm stroke and a 12 mm rod exiting BOTH covers, so the output force is identical in each direction because both strokes work on the rod-side area. At 0.5 MPa it delivers 571.8 N either way, rising to 800.5 N at 0.7 MPa, with a fixed TPU bumper at each end. The B code gives a male rod thread on the 12 mm rod, and the air ports are 1/8".
The short ISO 21287-class body saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, which is why it suits tight jigs, guards and gantry slides. The through-rod resists rotation and side load and gives a symmetric mount, and the rear rod can carry a sensor flag. In practice, plan on about 343 N of usable push at 0.5 MPa, which lifts roughly 29 kg vertically with a 2:1 margin. This model is discontinued; the current-production drop-in is the ACED40X45 - confirm the ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACED40X45B (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 (Ø40mm)
| Pressure | Force (both ways) |
|---|---|
| 0.5 MPa | 572 N |
| 0.7 MPa | 800 N |
| Max (@1.0 MPa) | 117 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 ACPD40X45B Is Used
Symmetric CNC fixture clamping
The through-rod clamps a machined aluminium housing from both sides of a jig with one cylinder, delivering 571.8 N in each direction at 0.5 MPa inside a compact fixture footprint.
Bidirectional pusher on packaging lines
A rod on each cover lets one unit divert cartons left or right on a conveyor without reversing plumbing, with the fixed TPU bumper decelerating the stroke at both ends.
Gantry flag carrier with rear rod
The back-end rod carries a position flag for a photoelectric or proximity sensor on a Z-axis gantry slide, keeping the 45 mm stroke envelope short where a full-length body will not fit.
Replacing the Airtac ACPD Double Rod Compact Cylinder ACPD40X45B with the ACED40X45B
At 571.8 N per side at 0.5 MPa, the 40 mm bore sits between the 32 mm (345.6 N) and 50 mm (881.2 N) double-rod versions, so step down for lighter clamping or up for heavier pressing. Note that a plain double-rod cylinder does not hold position when air is lost - add a rod lock or pilot check if the load must stay put. Mount it with FA/FB flange or LB foot brackets on the ISO 21287 face, and remember this unit has no magnet: only the -S code variant accepts CMSE / DMSE switches. For new projects, order the ACED40X45 instead.
Replacement checklist
- ✓ Current-production ACE → ACED40X45B
- ✓ 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 ACPD40X45B FAQ
Yes - it is a double-rod cylinder, so force is equal both ways because both strokes use the rod-side area. Figures: 571.8 N at 0.5 MPa, 800.5 N at 0.7 MPa, and a maximum of 116.6 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, with a 12 mm rod and 1/8" ports.
Order the ACED40X45, the current-production ISO 21287 successor made by swapping the P for an E. It matches the same 40 mm bore, 45 mm stroke and force class, and accepts the same FA/FB flange and LB foot mounting family. Because the ACP is DIN-standard, confirm the ISO 21287 mounting dimensions against your fixture before swapping. Also note the optional -S magnet code if you need CMSE / DMSE switch positions.
