This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACEJ12X30-30SB — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACEJ12X30-30SB 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 ACPJ12X30-30SB
The AirTAC Airtac ACPJ Adjustable Compact Cylinder ACPJ12X30-30SB is a double acting, adjustable stroke DIN-standard tight/compact air cylinder with a Ø12mm bore and 30mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACEJ12X30-30SB (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPJ Adjustable Compact Cylinder ACPJ12X30-30SB
Double acting compact cylinder with an adjustable extend stroke, the ACPJ12X30-30SB carries a 12 mm bore, 30 mm stroke and a male-threaded 6 mm rod. A stop screw trims the extend stroke anywhere inside the ordered 30 mm window, so one cylinder covers a 0-30 mm working range without changing parts. At 0.5 MPa it pushes 56.5 N and pulls 42.4 N, rising to 79.2 N at 0.7 MPa. The short ISO 21287-class body saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, which is why it slots into tight jigs and guarding where a full-length body will not fit.
Note that this model is discontinued: the current-production drop-in is the ACEJ12X30, which matches the same bore, stroke and force class - confirm the ISO 21287 mounting dimensions before swapping, since the ACP is DIN-standard. This unit carries the optional -S magnet, so CMSE or DMSE reed and solid-state switches can be mounted for end-of-stroke signalling. As a sizing rule of thumb, plan on about 34 N of usable push at 0.5 MPa (roughly 0.6 of the rated figure), which corresponds to lifting about 3 kg vertically with a 2:1 margin. A fixed TPU bumper sits at both ends, the body is hard-anodized aluminium with an S45C hard-chrome rod, and speed runs 30-500 mm/s at 0.15-1.0 MPa (22-145 psi).

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACEJ12X30-30SB (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 ACEJ12X30-30SB 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 ACPJ12X30-30SB Is Used
Small-part ejection from press dies
The 56.5 N push at 0.5 MPa is enough to kick light stamped parts off a die face, and the 0-30 mm trim lets the operator dial the ejector travel to the part height without shimming.
Position-flagged slide on an assembly bench
With the -S magnet fitted, a CMSE switch at each end confirms clamp and release states on a fixture that rejects a full-length body - the short build sits where an ISO 15552 profile cylinder cannot.
Sample press in a lab dosing station
About 3 kg of vertical lift capacity with a 2:1 margin suits pressing stoppers onto vials or sample tubes, and the male rod thread takes a knuckle for a pivoting platen.
Replacing the Airtac ACPJ Adjustable Compact Cylinder ACPJ12X30-30SB with the ACEJ12X30-30SB
For a 30 mm trim range at light loads, bore 12 delivers 56.5 N push at 0.5 MPa; step down is not available in this family, while stepping up to bore 16 gives 100.5 N and bore 20 gives 157.1 N at the same pressure if the load grows. The stop screw is a mechanical end stop for the extend stroke only - it does not lock the piston mid-stroke, and on air loss the rod can still drift, so add a separate holding valve where a load must stay put. Match FA/FB flange or LB foot mounts and I/Y rod knuckles to the ISO 21287 face; the male rod thread (B code) here suits external knuckles, and the PT port thread takes standard M5x0.8 fittings. Because the ACPJ is discontinued, order the ACEJ12X30 as the current replacement and verify mounting dimensions first.
Replacement checklist
- ✓ Current-production ACE → ACEJ12X30-30SB
- ✓ 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 ACPJ12X30-30SB FAQ
At 0.5 MPa it pushes 56.5 N and pulls 42.4 N; at 0.7 MPa those rise to 79.2 N and 59.4 N, with a theoretical maximum of 11.5 kgf at 1.0 MPa. The -30 code is a 30 mm adjustment window: a stop screw shortens the 30 mm extend stroke on site, giving a usable 0-30 mm range. It shortens the stroke only - it never lengthens it past the ordered stroke, and it is an end stop, not a mid-stroke lock.
No - the ACPJ family is discontinued. The current-production replacement is the ACEJ12X30 (swap the P for an E), a drop-in in the same bore, stroke and force class. Because the ACP is DIN-standard while the ACE follows ISO 21287, confirm the mounting dimensions against your fixture before swapping. This unit carries the optional -S magnet for CMSE / DMSE switches; on the replacement, order the -S code if you need switching.
