This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACEJ12X35-30SB — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACEJ12X35-30SB 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 ACPJ12X35-30SB
The AirTAC Airtac ACPJ Adjustable Compact Cylinder ACPJ12X35-30SB is a double acting, adjustable stroke DIN-standard tight/compact air cylinder with a Ø12mm bore and 35mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACEJ12X35-30SB (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPJ Adjustable Compact Cylinder ACPJ12X35-30SB
Double acting and adjustable in stroke, the ACPJ12X35-30SB is a discontinued DIN-standard compact cylinder with a 12 mm bore and a 35 mm stroke that an external stop screw trims anywhere within a 30 mm window, giving a usable extend range of 5-35 mm. Air pushes the rod out with 56.5 N and pulls it back with 42.4 N at 0.5 MPa; at 0.7 MPa those figures rise to 79.2 N and 59.4 N. The hard-anodized aluminium body is an ISO 21287-class short build that saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight jigs and guarding where a full-length body will not fit.
For sizing, plan on roughly 34 N of real work at 0.5 MPa (about 0.6 of the push rating), which is enough to lift about 2.9 kg vertically with a 2:1 margin. The S code on this model means the optional -S magnet is fitted, so CMSE / DMSE reed or solid-state switches can be clamped straight onto the body for end-of-stroke signals. This model is discontinued: the current-production drop-in is the ACEJ12X35, same bore, stroke and force class - confirm the ISO 21287 mounting dimensions before swapping, since the ACP series was built to DIN.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACEJ12X35-30SB (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 ACEJ12X35-30SB 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 ACPJ12X35-30SB Is Used
Small-part ejection from fixtures
The 56.5 N push at 0.5 MPa nudges machined pins or stamped clips off a jig, and the 5-35 mm trimmed stroke keeps the ejector travel matched to shallow pockets.
Position-verified clamping on test benches
With the -S magnet fitted, CMSE or DMSE switches confirm the rod has reached the trimmed stop before a lab fixture releases the part.
Light press-fitting of connectors
About 34 N of usable work at 0.5 MPa seats small terminals or bushings in electronics assemblies without crushing delicate housings.
Replacing the Airtac ACPJ Adjustable Compact Cylinder ACPJ12X35-30SB with the ACEJ12X35-30SB
At 12 mm bore this is the smallest force class in the family: 56.5 N push at 0.5 MPa. Step up to the 16 mm bore for 100.5 N push at the same pressure, or drop to a direct ACEJ12X35 if you want a current-production unit instead of this discontinued model. The male rod thread (B code) suits knuckle and bracket attachments, while the fitted -S magnet pairs with CMSE / DMSE switches. Note the stop screw only shortens the extend stroke - it is a mechanical end stop, not a mid-stroke lock, so the piston still drifts if air is lost. FA/FB flange and LB foot mounts bolt to the standard face.
Replacement checklist
- ✓ Current-production ACE → ACEJ12X35-30SB
- ✓ 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 ACPJ12X35-30SB FAQ
Push is 56.5 N and pull is 42.4 N at 0.5 MPa; at 0.7 MPa push rises to 79.2 N and pull to 59.4 N, with a theoretical maximum of 11.5 kgf at 1.0 MPa. The -30 code sets a 30 mm adjustment window, so the stop screw trims the 35 mm extend stroke anywhere down to 5 mm. The cylinder is double acting, runs on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi), and moves at 30-500 mm/s.
The hard-anodized aluminium body is an ISO 21287-class short build, roughly 50% shorter in mounting length than an ISO 15552 profile cylinder, with a fixed TPU bumper at each end and a 6 mm rod on a male thread. FA/FB flanges and LB feet bolt to the standard face, and the fitted -S magnet accepts CMSE / DMSE switches. The ACPJ family is discontinued - order the ACEJ12X35 as the current drop-in and confirm the ISO 21287 mounting dimensions first, since the ACP was built to DIN.
