This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACEJ12X160-50SB — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACEJ12X160-50SB 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 ACPJ12X160-50SB
The AirTAC Airtac ACPJ Adjustable Compact Cylinder ACPJ12X160-50SB 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 ACEJ12X160-50SB (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPJ Adjustable Compact Cylinder ACPJ12X160-50SB
This discontinued AirTAC model is a double acting compact cylinder with an adjustable extend stroke: the -50 stop screw trims the 160 mm stroke by up to 50 mm on site, giving a usable range of 110-160 mm. The 12 mm bore delivers 56.5 N push and 42.4 N pull at 0.5 MPa, rising to 79.2 N at 0.7 MPa, with a theoretical peak 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 about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into slim fixtures and guarding where a full-length body cannot. Because the -S code is fitted here, CMSE or DMSE reed and solid-state switches can be clamped to the body for end-of-stroke sensing. A practical sizing rule: plan on roughly 34 N (about 3.4 kg of force) of real work at 0.5 MPa, and expect it to lift about 2.9 kg vertically with a 2:1 margin. For new projects, order the current-production ACEJ12X160, which matches this bore, stroke and force class - confirm the ISO 21287 mounting dimensions before swapping, since the ACP is DIN-standard.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACEJ12X160-50SB (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 ACEJ12X160-50SB 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 ACPJ12X160-50SB Is Used
Lab sample ejector
Ejects sample trays from a compact analyzer drawer, with the 110-160 mm trim range matched to tray depth and the fitted magnet confirming full extension via a DMSE switch.
Small-bottle push-off
Pushes 50 ml cosmetic bottles off a filling conveyor lane; the 56.5 N push at 0.5 MPa clears light containers while the short body fits inside the lane guard.
Fixture height stop
Sets a variable stop height on an electronics assembly jig, trimmed anywhere from 110 to 160 mm with the -50 stop screw and sensed at the end by a CMSE reed switch.
Replacing the Airtac ACPJ Adjustable Compact Cylinder ACPJ12X160-50SB with the ACEJ12X160-50SB
At 12 mm bore this is the lightest force step in the family: 56.5 N push at 0.5 MPa. If your load needs more, step up to the 16 mm bore (100.5 N push at 0.5 MPa) or the 20 mm bore (157.1 N). 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 holding valve if the load must stay put. FA/FB flange and LB foot mountings bolt to the standard face, and the fitted -S magnet accepts CMSE / DMSE switches. This model is discontinued; the ACEJ12X160 is the drop-in successor in the same force class.
Replacement checklist
- ✓ Current-production ACE → ACEJ12X160-50SB
- ✓ 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 ACPJ12X160-50SB FAQ
Push is 56.5 N and pull is 42.4 N at 0.5 MPa; at 0.7 MPa push rises to 79.2 N and pull to 59.4 N, with a theoretical maximum of 11.5 kgf at 1.0 MPa. It runs on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), speed 30-500 mm/s, temperature -20 to +70 C, with a 6 mm male-thread rod and M5x0.8 ports. The 160 mm stroke is a made-to-order length above the 50 mm standard maximum for this bore, and the model is discontinued - the ACEJ12X160 is the current replacement.
The -50 code adds a stop screw that shortens the extend stroke by up to 50 mm, so the rod can be set anywhere in a 110-160 mm window; it cannot lengthen the stroke past 160 mm. A fixed TPU bumper at each end decelerates the piston at the ends only and never holds or brakes a load. Because the -S magnet is fitted, CMSE or DMSE reed and solid-state switches can be mounted on the body for position signals.
