This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACEJ12X100-75SB — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACEJ12X100-75SB 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 ACPJ12X100-75SB
The AirTAC Airtac ACPJ Adjustable Compact Cylinder ACPJ12X100-75SB is a double acting, adjustable stroke DIN-standard tight/compact air cylinder with a Ø12mm bore and 100mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACEJ12X100-75SB (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPJ Adjustable Compact Cylinder ACPJ12X100-75SB
Double acting and adjustable in stroke, the ACPJ12X100-75SB is a discontinued DIN-standard compact cylinder with a 12 mm bore, a 100 mm made-to-order stroke and a 75 mm trim window. An external stop screw shortens the extend stroke anywhere in that window, so the usable range is 25-100 mm on site. At 0.5 MPa it pushes 56.5 N and pulls 42.4 N, rising to 79.2 N / 59.4 N at 0.7 MPa. The S code means the magnet is fitted, so CMSE or DMSE reed and solid-state switches can be mounted directly on the hard-anodized aluminium body.
The short ISO 21287-class body saves about 50% of the mounting length of an ISO 15552 profile cylinder, which matters in slim fixtures and guarded assemblies. A practical sizing rule: plan on roughly 34 N of real work at 0.5 MPa, which lifts about 2.9 kg vertically with a 2:1 margin. The rod end is male thread (B code), the port is M5x0.8, and a fixed TPU bumper sits at both ends. This model is discontinued; the current-production drop-in is the ACEJ12X100, so confirm the ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACEJ12X100-75SB (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 ACEJ12X100-75SB 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 ACPJ12X100-75SB Is Used
Position-verified ejector on a small assembly cell
The fitted magnet drives a CMSE switch to confirm full extension before the next station indexes, while the 75 mm window lets one cylinder trim to different part heights.
Clamping thin PCB fixtures in electronics test
About 34 N of usable clamp force at 0.5 MPa holds lightweight boards without crushing, and the short body fits inside the fixture frame.
Sample pusher in a compact lab autosampler
The 25-100 mm adjustable range and 30-500 mm/s speed band let technicians dial in gentle, repeatable sample presentation.
Replacing the Airtac ACPJ Adjustable Compact Cylinder ACPJ12X100-75SB with the ACEJ12X100-75SB
Check the force ladder before ordering: bore 12 gives 56.5 N push at 0.5 MPa, bore 16 gives 100.5 N and bore 20 gives 157.1 N in the same compact family. If your part weight exceeds about 2.9 kg on a vertical lift, step up a bore. The 75 mm window suits stations where one cylinder must serve several part lengths; note the stop is a mechanical end stop only, so the piston still drifts on air loss and cannot hold a load mid-stroke. The 100 mm stroke is above the 50 mm standard maximum for bore 12, so it is made to order. FA/FB flange and LB foot mountings bolt to the ISO 21287 face. Order the ACEJ12X100 as the current replacement and verify mounting dimensions.
Replacement checklist
- ✓ Current-production ACE → ACEJ12X100-75SB
- ✓ 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 ACPJ12X100-75SB 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. The -75 code is a 75 mm adjustment window: a stop screw trims the 100 mm extend stroke down to as little as 25 mm. It is a mechanical end stop, not a mid-stroke lock, so the piston drifts if air is lost. Operating pressure is 0.15-1.0 MPa (22-145 psi), proof 1.5 MPa (215 psi), speed 30-500 mm/s, and the 100 mm stroke is a made-to-order length above the 50 mm standard maximum for bore 12.
Yes on this model: the S code means the optional -S magnet is fitted, so CMSE or DMSE reed and solid-state switches can be mounted. The ACPJ family is discontinued; the current-production drop-in is the ACEJ12X100 in the same bore, stroke and force class. Because the ACP is DIN-standard, confirm the ISO 21287 mounting dimensions before swapping.
