This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACED40X75SB — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACED40X75SB 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 ACPD40X75SB
The AirTAC Airtac ACPD Double Rod Compact Cylinder ACPD40X75SB is a double acting, double rod DIN-standard tight/compact air cylinder with a Ø40mm bore and 75mm stroke, 1/8" air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACED40X75SB (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPD Double Rod Compact Cylinder ACPD40X75SB
Double acting with a rod leaving both covers, the ACPD40X75SB pushes and pulls with identical force: 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 of the 40 mm piston. The 12 mm through-rod resists rotation and side load, gives a symmetric mount, and lets the rear rod carry a sensor flag, while fixed TPU bumpers pad each end of travel. Speed range is 30-500 mm/s over 0.15-1.0 MPa (22-145 psi) of clean, 40 um filtered air.
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. This unit carries the optional -S magnet, so CMSE or DMSE reed and solid-state switches can be fitted for end-of-stroke sensing. Note that the ACPD family is discontinued: the current-production drop-in is the ACED40X75, and you should confirm the ISO 21287 mounting dimensions before swapping. As a sizing rule, 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 ACED40X75SB (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 ACPD40X75SB Is Used
Symmetric clamp fixture
The equal 571.8 N force in both directions lets one through-rod clamp a machined aluminium housing from either side of a CNC jig without recalculating push versus pull.
Pusher on a packaging line
A 75 mm stroke diverts cartons between conveyor lanes at 30-500 mm/s, with the rear rod carrying a DMSE switch flag for position feedback.
Indexing table lift assist
With about 29 kg of vertical lift at a 2:1 margin, the cylinder raises a small rotary indexing plate under a drill head, guided by the rotation-resistant through-rod.
Replacing the Airtac ACPD Double Rod Compact Cylinder ACPD40X75SB with the ACED40X75SB
At 571.8 N per side at 0.5 MPa, the 40 mm bore sits mid-range: step down to the 32 mm bore (345.6 N both ways) for lighter clamping, or up to the 50 mm bore (881.2 N) when the job needs more muscle. The 75 mm stroke is well inside the 200 mm maximum standard stroke for this bore, so it is a catalogue item. The male rod thread (B code) suits rod knuckles and external tooling, and FA/FB flange or LB foot mounting bolts onto the standard face. Remember that a plain through-rod cylinder drifts when air is lost, so add a rod lock or pilot check for a held load, and order the ACED40X75 as the current replacement for new builds.
Replacement checklist
- ✓ Current-production ACE → ACED40X75SB
- ✓ 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 ACPD40X75SB FAQ
Because a rod exits both covers, force is equal both ways: 571.8 N at 0.5 MPa and 800.5 N at 0.7 MPa, on the rod-side area of the 40 mm bore. At the full 1.0 MPa rating the peak is 116.6 kgf. Operating pressure is 0.15-1.0 MPa (22-145 psi) with 1.5 MPa (215 psi) proof pressure, and speed runs 30-500 mm/s.
No - the ACPD family is discontinued. The current-production drop-in is the ACED40X75 (swap the P for an E), which matches the same bore, stroke and force class in the ISO 21287 short-body format. Confirm the ISO 21287 mounting dimensions against your fixture before swapping. This unit's -S magnet accepts CMSE / DMSE switches, and the fixed TPU bumpers at both ends simply decelerate the piston.
