This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACEJ12X120-100SB — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACEJ12X120-100SB 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 ACPJ12X120-100SB
The AirTAC Airtac ACPJ Adjustable Compact Cylinder ACPJ12X120-100SB is a double acting, adjustable stroke DIN-standard tight/compact air cylinder with a Ø12mm bore and 120mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACEJ12X120-100SB (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPJ Adjustable Compact Cylinder ACPJ12X120-100SB
Double acting and adjustable, the ACPJ12X120-100SB is a discontinued DIN-standard compact cylinder with a 12 mm bore and a 120 mm stroke trimmed by a 100 mm adjustment window. A stop screw shortens the extend stroke on site, giving a usable range of 20-120 mm; it cannot lengthen the stroke past the ordered 120 mm. At 0.5 MPa it pushes 56.5 N and pulls 42.4 N, rising to 79.2 N push at 0.7 MPa, with a theoretical maximum of 11.5 kgf at 1.0 MPa. The 120 mm stroke exceeds the 50 mm standard maximum for this bore, so it is a made-to-order build.
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 where a full-length body will not fit. This -S version carries the optional magnet, so CMSE or DMSE reed and solid-state switches can be mounted for end-of-stroke sensing, and the B code gives a male rod thread. A fixed TPU bumper at each end absorbs end-of-travel impact but never locks or holds a load - on air loss the piston drifts. Note the family is discontinued: the current-production drop-in is ACEJ12X120, and buyers should confirm ISO 21287 mounting dimensions before swapping. As a rule of thumb, plan on about 34 N of real work at 0.5 MPa, which lifts roughly 1.7 kg vertically with a 2:1 margin.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACEJ12X120-100SB (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 ACEJ12X120-100SB 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 ACPJ12X120-100SB Is Used
Small-part ejection from plastic molds
The 56.5 N push at 0.5 MPa is enough to kick light molded caps or bushings off a mold face, and the 20-120 mm adjustable range lets the setter dial the eject distance without changing cylinders.
Position-verified test fixtures
With the fitted -S magnet driving CMSE or DMSE switches, a bench-top electronics test jig can confirm the 6 mm rod has reached the trimmed extend position before the probe cycle starts.
Light clamping on compact assembly stations
About 34 N of usable work at 0.5 MPa suits holding small PCB brackets or connector housings during a screwdriving step, where the short body fits inside a tight gantry frame.
Replacing the Airtac ACPJ Adjustable Compact Cylinder ACPJ12X120-100SB with the ACEJ12X120-100SB
Size both ways: if 56.5 N push at 0.5 MPa is more than the job needs, the smaller ACPJ10 class is lighter still; if the load approaches the 34 N working band, step up to the 16 mm bore, which delivers 100.5 N push at 0.5 MPa. The stop screw is a mechanical end stop for the extend stroke only - it is not a mid-stroke lock, so do not rely on it to hold a vertical load when air is lost. FA/FB flange and LB foot mountings bolt to the standard face, and the fitted -S magnet accepts CMSE / DMSE switches. Order ACEJ12X120 as the current replacement and verify ISO 21287 mounting dimensions before the swap.
Replacement checklist
- ✓ Current-production ACE → ACEJ12X120-100SB
- ✓ 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 ACPJ12X120-100SB 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 -100 code is a 100 mm adjustment window, so the stop screw can trim the 120 mm extend stroke anywhere down to 20 mm. Operating pressure is 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), speed 30-500 mm/s, port M5x0.8, rod 6 mm with male thread. The 120 mm stroke is a made-to-order build above the 50 mm standard maximum for this bore.
The short-body build saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it fits shallow jigs and guards. It is a hard-anodized aluminium body with an S45C hard-chrome rod and fixed TPU bumpers at both ends. The ACPJ family is discontinued; the current-production drop-in is ACEJ12X120 in the same bore, stroke and force class - confirm the ISO 21287 mounting dimensions before swapping.
