This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACEJ12X70-75S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACEJ12X70-75S 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 ACPJ Adjustable Compact Cylinder ACPJ12X70-75S
The AirTAC Airtac ACPJ Adjustable Compact Cylinder ACPJ12X70-75S is a double acting, adjustable stroke DIN-standard tight/compact air cylinder with a Ø12mm bore and 70mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACEJ12X70-75S (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPJ Adjustable Compact Cylinder ACPJ12X70-75S
This compact AirTAC cylinder is double acting, with air driving the rod out and pulling it back, and its -75 code gives a 75 mm adjustment window: an external stop screw trims the 70 mm extend stroke on site, so the usable range is 0-70 mm. The 12 mm bore delivers 56.5 N push and 42.4 N pull at 0.5 MPa, rising to 79.2 N at 0.7 MPa, with a theoretical ceiling of 11.5 kgf at 1.0 MPa. In practice plan for roughly 34 N (about 0.6 of the push rating) of real work at 0.5 MPa, which lifts about 2.8 kg vertically with a 2:1 margin.
Note that the 70 mm stroke exceeds the 50 mm maximum standard stroke for bore 12, so this unit is made to order. The short ISO 21287-class body saves about 50% of the mounting length of an ISO 15552 profile cylinder, the fixed TPU bumper decelerates at both ends, and the fitted -S magnet accepts CMSE / DMSE reed or solid-state switches. This model is discontinued; the current drop-in is ACEJ12X70, so confirm ISO 21287 mounting dimensions before swapping because the ACP is DIN-standard.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACEJ12X70-75S (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 (Ø12mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 57 N | 42 N |
| 0.7 MPa | 79 N | 59 N |
| Max (@1.0 MPa) | 12 kgf | |
The ACEJ12X70-75S produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

Where the Airtac ACPJ Adjustable Compact Cylinder ACPJ12X70-75S Is Used
Micro assembly press
A 12 mm bore pushing 56.5 N at 0.5 MPa seats small connectors or labels in electronics fixtures, with the stop screw trimming the extend stroke to a repeatable 0-70 mm window.
Vision inspection slide
The fitted -S magnet drives CMSE or DMSE switches for end-of-stroke confirmation on a compact camera gantry, where the short body fits inside a tight guard.
Lab sample ejector
About 2.8 kg of vertical lift capability with a 2:1 margin clears sample vials from a tray in a compact analytical instrument, using the M3x0.5 female rod thread for tooling.
Replacing the Airtac ACPJ Adjustable Compact Cylinder ACPJ12X70-75S with the ACEJ12X70-75S
For a 70 mm stroke at this force level, 12 mm gives 56.5 N push at 0.5 MPa; step up to bore 16 (100.5 N) if the load is heavier, or down only for very light positioning. The adjuster is a mechanical end stop for the extend stroke, not a mid-stroke lock, so the piston still drifts on air loss. FA/FB flange and LB foot mountings bolt to the standard face, and the fitted -S magnet pairs with CMSE / DMSE switches. Since ACPJ is discontinued, order ACEJ12X70 as the current-production equivalent and verify the ISO 21287 mounting dimensions.
Replacement checklist
- ✓ Current-production ACE → ACEJ12X70-75S
- ✓ Same bore / stroke / force class
- ✓ Confirm ISO 21287 mounting dimensions
- ✓ Port/thread type (PT / G)
- ✓ Add -S for magnet if you need sensors
Airtac ACPJ Adjustable Compact Cylinder ACPJ12X70-75S FAQ
At 0.5 MPa it pushes 56.5 N and pulls 42.4 N; at 0.7 MPa it pushes 79.2 N and pulls 59.4 N; theoretical maximum is 11.5 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, air filtered to 40 um, temperature -20 to +70 C. The 70 mm stroke is non-standard for bore 12 (max standard 50 mm), so it is made to order.
The -75 code is a 75 mm adjustment window: an external stop screw shortens the extend stroke on site anywhere from 0 to 70 mm, and a fixed TPU bumper decelerates at both ends. The stop is not a load-holding brake. This ACPJ is discontinued; the current drop-in is ACEJ12X70 (same bore, stroke and force class), and you should confirm ISO 21287 mounting dimensions before swapping since the ACP is DIN-standard.
