This model is discontinued

AirTAC has phased out the MAL series. The drop-in replacement is ACED40X80B — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACED40X80B 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 ACPD40X80B

The AirTAC Airtac ACPD Double Rod Compact Cylinder ACPD40X80B is a double acting, double rod DIN-standard tight/compact air cylinder with a Ø40mm bore and 80mm stroke, 1/8" air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACED40X80B (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPD Double Rod Compact Cylinder ACPD40X80B

Double acting with a rod leaving both covers, the ACPD40X80B pushes and pulls with identical force because each stroke works on the rod-side area: 571.8 N at 0.5 MPa and 800.5 N at 0.7 MPa in either direction. The 12 mm through-rod resists rotation and side load, and the rear rod stub can carry a sensor flag on a pick-and-place gantry. Its ISO 21287 short body saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight guarding where a full-length body cannot.

This 40 mm unit is discontinued; the current-production drop-in is ACED40X80, the same bore, stroke and force class, so confirm the ISO 21287 mounting dimensions before swapping. The male rod thread (B code) bolts to I/Y knuckles, and FA/FB flange or LB foot brackets fit the standard face. Plan on about 343 N of usable work at 0.5 MPa, which is roughly 35 kg of vertical lift with a 2:1 margin. Note there is no magnet fitted on this code; order the -S variant if you need CMSE or DMSE switches. A fixed TPU bumper sits at both ends, and speed runs 30-500 mm/s at 0.15-1.0 MPa (22-145 psi).

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACED40X80B (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)

PressureForce (both ways)
0.5 MPa572 N
0.7 MPa800 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 ACPD40X80B Is Used

precision_manufacturing

Symmetric fixture clamping

The equal 571.8 N force in both directions lets one 40 mm bore clamp and release a machined housing in a CNC fixture without recalculating push versus pull.

conveyor_belt

Pusher with rear sensor flag

On a bottling line transfer conveyor, the back-end rod carries a flag for a proximity sensor while the front rod pushes cartons at 30-500 mm/s.

swap_horiz

Gantry slide transfer

The through-rod of the ACPD40X80B stabilizes a horizontal slide moving 35 kg-class aluminum panels between two assembly stations, lifting about 35 kg vertically with margin.

Replacing the Airtac ACPD Double Rod Compact Cylinder ACPD40X80B with the ACED40X80B

Size between bores: a 32 mm double-rod unit gives 345.6 N at 0.5 MPa, while a 50 mm version reaches 881.2 N, so the 40 mm at 571.8 N sits mid-range for clamping and transfer duties. The 80 mm stroke is well inside the 200 mm maximum standard stroke for this bore, so no made-to-order build is needed. A plain double-rod cylinder drifts when air is lost, so add a rod lock or pilot check if the load must stay put. Match FA/FB flange or LB foot mounts to your fixture, and remember the optional -S magnet is required before any CMSE or DMSE switch will read. For new projects, specify ACED40X80 instead.

Replacement checklist

  • ✓ Current-production ACE → ACED40X80B
  • ✓ 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 ACPD40X80B FAQ

Because a rod exits both covers, force is equal in both directions: 571.8 N at 0.5 MPa and 800.5 N at 0.7 MPa, both ways, with 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, and the port is 1/8" (PT thread on this code).

AirTAC no longer produces the ACPD family. The current drop-in is ACED40X80, the ISO 21287 successor with the same 40 mm bore, 80 mm stroke and force class. Before swapping, confirm the ISO 21287 mounting dimensions against your fixture, since the ACP was built to a DIN-standard footprint. FA/FB flange, LB foot and I/Y knuckle options carry over.
