This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACEJ12X100-40SB — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACEJ12X100-40SB 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 ACPJ12X100-40SB
The AirTAC Airtac ACPJ Adjustable Compact Cylinder ACPJ12X100-40SB 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 ACEJ12X100-40SB (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPJ Adjustable Compact Cylinder ACPJ12X100-40SB
The ACPJ12X100-40SB is a double acting compact cylinder with an adjustable extend stroke: the -40 stop screw trims the 100 mm stroke anywhere inside a 40 mm window, giving a usable range of 60-100 mm. Air works on both faces of the 12 mm piston, so the rod extends with 56.5 N and retracts with 42.4 N at 0.5 MPa, rising to 79.2 N on the push stroke at 0.7 MPa. The 100 mm stroke exceeds the 50 mm standard limit for bore 12, so this unit is a made-to-order build. Note that this ACPJ model is discontinued; the current-production successor is the ACEJ12X100, and buyers should confirm the ISO 21287 mounting dimensions before swapping, since the ACP series was built to a DIN-standard footprint.
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 slim jigs, small gating brackets and cramped test fixtures. In practice, plan on about 34 N of real work at 0.5 MPa (roughly 60% of the rated push), and expect it to lift about 2.9 kg vertically once a 2:1 margin is applied. The -S code on this model means the position magnet is fitted, so CMSE or DMSE reed and solid-state switches can be clamped straight onto the hard-anodized aluminium body. A fixed TPU bumper sits at each end, the S45C rod carries a hard-chrome finish with a male thread, and speed runs 30-500 mm/s across 0.15-1.0 MPa (22-145 psi).

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACEJ12X100-40SB (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 ACEJ12X100-40SB 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 ACPJ12X100-40SB Is Used
Compact lab test stations
The 60-100 mm adjustable window and 56.5 N push at 0.5 MPa suit small sample-clamping actuators on bench-top leak and fatigue rigs where every millimetre of length counts.
Micro-part ejection on assembly fixtures
With about 34 N of practical working force and a 6 mm male-thread rod, this cylinder punches tiny stamped or moulded parts out of shallow nests in electronics assembly tooling.
Position-verified slide gates
Because the -S magnet is fitted, CMSE or DMSE switches confirm gate open/closed states on small diverters and inspection shutters, with the stop screw set anywhere from 60 to 100 mm of travel.
Replacing the Airtac ACPJ Adjustable Compact Cylinder ACPJ12X100-40SB with the ACEJ12X100-40SB
Bore 12 is the smallest in this family: at 0.5 MPa it pushes 56.5 N and pulls 42.4 N, so if your load needs more, step up to bore 16 (100.5 N push) or bore 20 (157.1 N push) in the same compact envelope. The -40 adjuster is a mechanical end stop for the extend stroke only - it does not hold a load if air pressure is lost, so add a separate locking valve where that matters. This version has a male rod thread (B) and PT ports; FA/FB flange or LB foot mounts bolt to the standard face. If you are designing new tooling, specify the ACEJ12X100 instead, as the ACPJ line is discontinued.
Replacement checklist
- ✓ Current-production ACE → ACEJ12X100-40SB
- ✓ 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 ACPJ12X100-40SB FAQ
At 0.5 MPa it pushes 56.5 N and pulls 42.4 N; at 0.7 MPa those figures rise to 79.2 N push and 59.4 N pull, with a theoretical maximum of 11.5 kgf at 1.0 MPa. The -40 code gives a 40 mm adjustment window, so the extend stroke can be trimmed anywhere between 60 and 100 mm. The 100 mm stroke is a made-to-order length because bore 12 tops out at 50 mm as a standard stroke. Operating range is 0.15-1.0 MPa (22-145 psi) at 30-500 mm/s.
It is a short-body compact cylinder whose hard-anodized aluminium body saves about 50% of the mounting length of an ISO 15552 profile cylinder, with a fixed TPU bumper at each end and an M5x0.8 port. The -S magnet on this unit accepts CMSE and DMSE switches for end-position sensing. The ACPJ family is no longer in production: order the ACEJ12X100, the current ISO 21287 drop-in in the same bore and stroke class, and confirm the mounting dimensions against your fixture before the swap.
