This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACED40X75S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACED40X75S 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 ACPD40X75S
The AirTAC Airtac ACPD Double Rod Compact Cylinder ACPD40X75S 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 ACED40X75S (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPD Double Rod Compact Cylinder ACPD40X75S
A double acting compact cylinder with a rod leaving both covers, the ACPD40X75S 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 40 mm bore drives a 12 mm through-rod over a 75 mm stroke, with a fixed TPU bumper at each end and air supply from 0.15-1.0 MPa (22-145 psi).
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. The S code means the optional -S magnet is fitted on this unit, so CMSE or DMSE reed and solid-state switches can be clipped on for end-of-stroke sensing. Note this model is discontinued; the current-production replacement is the ACED40X75, which matches the same bore, stroke and force class - confirm the ISO 21287 mounting dimensions before swapping. As a sizing guide, the 571.8 N output at 0.5 MPa equals about 58 kgf, so plan on lifting roughly 29 kg vertically with a 2:1 margin.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACED40X75S (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 ACPD40X75S Is Used
Benchtop press fixture
The 800.5 N at 0.7 MPa in both directions suits a small marking or staking press on an electronics assembly bench, with the 75 mm stroke clearing the part for manual loading.
Reciprocating guide rail
A rod on each end lets the rear rod anchor a fixture while the front rod drives a sliding guide on a packaging machine, keeping the mount symmetric over the 30-500 mm/s speed range.
Position-verified clamp
Because the -S magnet is fitted, CMSE or DMSE switches confirm full clamp and release on an automotive subassembly jig without external proximity hardware.
Replacing the Airtac ACPD Double Rod Compact Cylinder ACPD40X75S with the ACED40X75S
At 571.8 N per side at 0.5 MPa, the 40 mm bore suits clamping and press-fit work around 340 N of usable effort once you derate for real-world friction. Step down to the 32 mm bore (345.6 N) for lighter jigs or up to the 50 mm bore (881.2 N) when the part weight grows. The through-rod resists rotation and side load, and the rear rod can carry a sensor flag. Remember the piston drifts if air is lost - add a rod lock or pilot check valve where a load must stay put. FA/FB flange and LB foot mountings bolt to the standard face. This model is discontinued; order the ACED40X75 as the drop-in successor.
Replacement checklist
- ✓ Current-production ACE → ACED40X75S
- ✓ 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 ACPD40X75S FAQ
Yes - the double-rod design exposes the rod-side area on both strokes, so output is equal each way: 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. The 40 mm bore uses a 12 mm rod, a 1/8" port and an M8x1.25 female rod thread. It runs on 0.15-1.0 MPa (22-145 psi) air filtered to 40 um at 30-500 mm/s.
Order the ACED40X75, the current-production ISO 21287 successor made by swapping the P for an E. It matches the same 40 mm bore, 75 mm stroke and force class, and accepts the FA/FB flange and LB foot mounting family. Since the ACP follows a DIN-standard layout, confirm the ISO 21287 mounting dimensions against your fixture before the swap.
