This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACEJ12X160-20B — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACEJ12X160-20B 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 ACPJ12X160-20B
The AirTAC Airtac ACPJ Adjustable Compact Cylinder ACPJ12X160-20B is a double acting, adjustable stroke DIN-standard tight/compact air cylinder with a Ø12mm bore and 160mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACEJ12X160-20B (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPJ Adjustable Compact Cylinder ACPJ12X160-20B
This discontinued AirTAC model is a double acting compact cylinder with an adjustable extend stroke: a stop screw trims the 160 mm stroke by up to 20 mm on site, giving a usable range of 140-160 mm. The 12 mm bore delivers 56.5 N push and 42.4 N pull at 0.5 MPa, rising to 79.2 N push at 0.7 MPa, with a theoretical ceiling of 11.5 kgf at 1.0 MPa. The 160 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, which is why it suits slim jigs and guarded stations. As a rule of thumb, plan on about 34 N (0.6 x 56.5 N) of real work at 0.5 MPa, which corresponds to lifting roughly 2.9 kg vertically with a 2:1 margin. The B code gives a male rod thread on the 6 mm rod, the port is M5x0.8, and no magnet is fitted - the optional -S code is required before any CMSE / DMSE switch can be used. For new projects, order the current-production ACEJ12X160 and confirm the ISO 21287 mounting dimensions first, since the ACP family is DIN-standard.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACEJ12X160-20B (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 ACEJ12X160-20B 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 ACPJ12X160-20B Is Used
Small-part ejection from plastic molds
The 56.5 N push at 0.5 MPa is enough to kick lightweight molded caps or bushings off a fixture, and the 140-160 mm adjustable reach clears deep mold pockets without a longer frame.
Slide gating on electronics assembly lines
A 6 mm male-thread rod drives a light shutter or carrier between two positions; order the -S magnet version if CMSE / DMSE end-position signaling is needed later.
Sample transfer in lab automation
The 2.9 kg vertical-lift equivalent with a 2:1 margin suits raising small vial trays or sensor heads, and the short body fits inside compact instrument enclosures.
Replacing the Airtac ACPJ Adjustable Compact Cylinder ACPJ12X160-20B with the ACEJ12X160-20B
At 12 mm bore this is the smallest force class in the range: 56.5 N push at 0.5 MPa versus 100.5 N for a 16 mm bore and 157.1 N for a 20 mm bore, so step up a size if your part weight or friction load approaches 34 N of real demand. 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 still drifts, so add a separate clamp if you must hold position. FA/FB flange and LB foot mountings bolt to the standard face, and the male thread from the B code accepts I/Y rod knuckles directly. This model is discontinued; the drop-in successor is ACEJ12X160 in the same bore, stroke and force class - verify the ISO 21287 mounting dimensions before swapping.
Replacement checklist
- ✓ Current-production ACE → ACEJ12X160-20B
- ✓ 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 ACPJ12X160-20B 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; the theoretical maximum is 11.5 kgf at 1.0 MPa. The -20 code sets a 20 mm adjustment window: an external stop screw shortens the 160 mm extend stroke by up to 20 mm, so the working range is 140-160 mm. It cannot lengthen the stroke past 160 mm, and the stop is not a mid-stroke lock - the rod drifts if air is lost. Speed range is 30-500 mm/s and operating pressure is 0.15-1.0 MPa (22-145 psi).
No - the ACPJ family is discontinued and no longer in production. The current-production drop-in is ACEJ12X160, which matches the same 12 mm bore, 160 mm stroke and force class in the ISO 21287 short-body format. Because the ACP is DIN-standard, confirm the ISO 21287 mounting dimensions before swapping. Also note this unit has no magnet fitted; the optional -S code is what enables CMSE / DMSE switch mounting, and the 160 mm stroke is a made-to-order length above the 50 mm standard maximum for this bore.
