This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACED40X35 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACED40X35 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 ACPD40X35
The AirTAC Airtac ACPD Double Rod Compact Cylinder ACPD40X35 is a double acting, double rod DIN-standard tight/compact air cylinder with a Ø40mm bore and 35mm stroke, 1/8" air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACED40X35 (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPD Double Rod Compact Cylinder ACPD40X35
A double acting compact cylinder with a rod leaving both covers, the ACPD40X35 delivers the same 571.8 N at 0.5 MPa (800.5 N at 0.7 MPa) on every stroke, since both sides work on the rod-side area. The 40 mm bore drives a 12 mm through-rod over a 35 mm stroke, with a fixed TPU bumper at each end and 1/8" ports. Air supply is 0.15-1.0 MPa (22-145 psi), speed 30-500 mm/s, and the hard-anodized aluminium body carries an S45C hard-chrome rod.
The short ISO 21287 body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight guards and jigs. The back-end rod is handy for a sensor flag or a symmetric second mount, and the through-rod resists rotation and side load. Note the magnet is not fitted on this code; order the -S version to enable CMSE / DMSE switches. This model is discontinued, and the current drop-in is the ACED40X35 - confirm the ISO 21287 mounting dimensions before swapping. As a planning figure, treat roughly 343 N (about 29 kg lifted vertically with a 2:1 margin) as the usable force at 0.5 MPa.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACED40X35 (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 ACPD40X35 Is Used
Symmetric jig clamping
The 571.8 N equal force in both directions clamps and releases a machined housing in a drilling fixture with identical holding pressure either way.
Two-position slide flag
With the -S magnet and CMSE switches, the back-end rod carries a flag so a packaging machine confirms both end positions of the 35 mm stroke.
Pusher between rollers
The through-rod resists side load as the cylinder kicks off-spec cartons sideways on a conveyor line, with the TPU bumpers softening each end hit.
Replacing the Airtac ACPD Double Rod Compact Cylinder ACPD40X35 with the ACED40X35
At 571.8 N per direction, bore 40 sits between the 32 mm (345.6 N) and 50 mm (881.2 N) double-rod options - step down for lighter clamping, up when the part weight demands more. The 35 mm stroke is well inside the 200 mm standard limit for this bore. Remember the piston drifts when air is lost; add a rod lock or pilot check if the load must stay put. FA/FB flange or LB foot mounts bolt to the ISO 21287 face, and the optional -S magnet unlocks CMSE / DMSE switch position feedback. For new projects, specify the ACED40X35, the current-production successor.
Replacement checklist
- ✓ Current-production ACE → ACED40X35
- ✓ 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 ACPD40X35 FAQ
Because a rod exits both covers, output is equal in both directions: 571.8 N at 0.5 MPa and 800.5 N at 0.7 MPa, with a maximum of 116.6 kgf at 1.0 MPa. Both strokes use the rod-side area, so there is no push-versus-pull difference. In practice, plan on about 343 N of working force at 0.5 MPa, roughly 29 kg lifted vertically with a 2:1 margin.
It is a discontinued DIN-standard compact model; the current drop-in is the ACED40X35, so confirm the ISO 21287 mounting dimensions before swapping. The body is hard-anodized aluminium with a fixed TPU bumper at each end, 1/8" ports, female M8x1.25 rod thread and FA/FB or LB mounting options. The magnet is the optional -S code - without it no CMSE or DMSE switch can be fitted.
