This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACED40X65SB — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACED40X65SB 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 ACPD40X65SB
The AirTAC Airtac ACPD Double Rod Compact Cylinder ACPD40X65SB is a double acting, double rod DIN-standard tight/compact air cylinder with a Ø40mm bore and 65mm stroke, 1/8" air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACED40X65SB (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPD Double Rod Compact Cylinder ACPD40X65SB
A double acting compact cylinder with a rod leaving both covers, the ACPD40X65SB pushes and pulls with identical output: 571.8 N at 0.5 MPa and 800.5 N at 0.7 MPa in either direction, because both strokes work on the rod-side area. The through-rod resists rotation and side load, gives a symmetric mounting face, and the rear rod can carry a sensor flag. A fixed TPU bumper sits at each end and stroke speed runs 30-500 mm/s.
The short ISO 21287-class body saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight fixtures and guarding. 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 - enough for a loaded 25 kg pallet tray. Note this model is discontinued: the current-production drop-in is ACED40X65, so confirm the ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACED40X65SB (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 ACPD40X65SB Is Used
Reciprocating transfer carriage
The through-rod drives a small parts carriage on a conveyor transfer station; equal 571.8 N force in both directions keeps return speed and push identical without a second cylinder.
Pick-and-place lift on a PCB line
With about 29 kg of vertical lift capacity at a 2:1 margin, the 40 mm bore raises loaded electronics trays between an SMT feeder and an inspection bench, while the -S magnet feeds CMSE switches for position feedback.
Symmetric carton pusher
A packaging machine pushes cartons across a checkweigher; the rear rod doubles as a mounting point for a DMSE sensor flag, and the short body fits inside the machine guard where a full-length cylinder would not.
Replacing the Airtac ACPD Double Rod Compact Cylinder ACPD40X65SB with the ACED40X65SB
At 40 mm bore this unit delivers 571.8 N both ways at 0.5 MPa. If your load needs less, the 32 mm bore gives 345.6 N; if you need more, the 50 mm bore reaches 881.2 N. The 65 mm stroke sits well inside the 200 mm maximum standard stroke for this bore, so it is a catalogue item, not a made-to-order build. Remember that a plain double-rod cylinder drifts when air is lost - add a rod lock or pilot check if the load must stay put.
This version carries the optional -S magnet, so CMSE or DMSE reed and solid-state switches can be clipped on for end-of-stroke signalling, and the B code gives a male rod thread. FA/FB flange or LB foot mounts bolt to the ISO 21287 face. Since ACPD is discontinued, order ACED40X65 as the current replacement and verify mounting dimensions.
Replacement checklist
- ✓ Current-production ACE → ACED40X65SB
- ✓ 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 ACPD40X65SB FAQ
No - this is a double-rod cylinder, so a rod exits both covers and both strokes use the rod-side area. Force is 571.8 N at 0.5 MPa and 800.5 N at 0.7 MPa, equal in both directions, 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), and speed 30-500 mm/s.
Order ACED40X65, the ISO 21287 ACE series successor made by swapping the P for an E. It matches the same 40 mm bore, 65 mm stroke and force class with a matching short body and mounting family (FA/FB flange, LB foot). Because the ACP is DIN-standard, confirm the ISO 21287 mounting dimensions before the swap. The male rod thread (B) and the -S magnet for CMSE / DMSE switches carry over as options.
