This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACED40X90B — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACED40X90B 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 ACPD40X90B
The AirTAC Airtac ACPD Double Rod Compact Cylinder ACPD40X90B is a double acting, double rod DIN-standard tight/compact air cylinder with a Ø40mm bore and 90mm stroke, 1/8" air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACED40X90B (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPD Double Rod Compact Cylinder ACPD40X90B
Double acting with a rod leaving both covers, the ACPD40X90B pushes and pulls with identical force - 571.8 N at 0.5 MPa and 800.5 N at 0.7 MPa in either direction, since both strokes work on the rod-side area of the 40 mm bore. The male rod thread (B code) bolts straight to tooling, and the through-rod resists rotation and side load while the rear rod can carry a sensor flag. This 90 mm stroke sits well inside the 200 mm standard range for bore 40.
The short ISO 21287-class body cuts roughly 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight fixtures, guards and gantries. A hard-anodized aluminium body runs with an S45C hard-chrome rod, fixed TPU bumpers sit at both ends, and speed spans 30-500 mm/s at 0.15-1.0 MPa (22-145 psi). Note: this model is discontinued - the current drop-in is ACED40X90, so confirm ISO 21287 mounting dimensions before swapping. As a rule of thumb, plan on about 343 N of real work at 0.5 MPa, which lifts roughly 29 kg vertically with a 2:1 margin.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACED40X90B (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 ACPD40X90B Is Used
Symmetric CNC fixture clamping
Equal 571.8 N clamp and release force in both directions suits a machining fixture where the same clamping pressure is needed on the advance and return stroke.
Reciprocating carrier on a packaging line
The through-rod keeps a sliding carrier square at 30-500 mm/s, with the rear rod available to trip a position flag between stations.
Press-fit ejection in an electronics assembly cell
About 29 kg of vertical lift capacity with a 2:1 margin handles ejecting connector housings from a nest; the male rod thread takes a custom punch tip directly.
Replacing the Airtac ACPD Double Rod Compact Cylinder ACPD40X90B with the ACED40X90B
At 571.8 N per side, bore 40 covers mid-duty clamping and lifting. Step down to bore 32 (345.6 N at 0.5 MPa) for lighter loads, or up to bore 50 (881.2 N) when the part weight climbs. If the load must stay put when air is lost, add a rod lock or pilot check - this cylinder drifts. Mount with FA/FB flange or LB foot on the ISO 21287 face; the optional -S magnet enables CMSE / DMSE switches (this unit has no magnet). Order ACED40X90 as the current-production replacement.
Replacement checklist
- ✓ Current-production ACE → ACED40X90B
- ✓ 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 ACPD40X90B FAQ
No - it is a double-rod cylinder, so force is equal both ways: 571.8 N at 0.5 MPa and 800.5 N at 0.7 MPa, both measured on the rod-side area of the 40 mm bore. Peak output at 1.0 MPa reaches about 116.6 kgf. Operating range is 0.15-1.0 MPa (22-145 psi) with a 1.5 MPa (215 psi) proof pressure.
Order ACED40X90, the current-production ISO 21287 successor made by swapping the P for an E. It matches the same 40 mm bore, 90 mm stroke and force class with a matching short body and mounting family, but confirm the ISO 21287 mounting dimensions against your fixture before swapping, since the ACP follows the older DIN-standard layout.
