This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACEJ12X80-50SB — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACEJ12X80-50SB 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 ACPJ12X80-50SB
The AirTAC Airtac ACPJ Adjustable Compact Cylinder ACPJ12X80-50SB is a double acting, adjustable stroke DIN-standard tight/compact air cylinder with a Ø12mm bore and 80mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACEJ12X80-50SB (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPJ Adjustable Compact Cylinder ACPJ12X80-50SB
This is a double acting, adjustable-stroke compact cylinder in the AirTAC ACPJ family, now discontinued. The 12 mm bore delivers 56.5 N push and 42.4 N pull at 0.5 MPa (79.2 N / 59.4 N at 0.7 MPa), with a theoretical peak of 11.5 kgf at 1.0 MPa. The -50 code gives a 50 mm adjustment window: a stop screw trims the 80 mm extend stroke down to as little as 30 mm, so one cylinder covers a 30-80 mm working range. The 80 mm stroke exceeds the 50 mm standard maximum for bore 12, so it is a made-to-order build. The hard-anodized aluminium body is an ISO 21287-class short design that saves about 50% of the mounting length of an ISO 15552 profile cylinder.
The S code means the optional magnet is fitted on this unit, so CMSE or DMSE reed and solid-state switches can be mounted directly on the body. The B code gives a male rod thread (6 mm rod, PT ports). A fixed TPU bumper sits at both ends and only decelerates the piston near the ends of travel; the stop screw is a mechanical end stop, not a mid-stroke lock, so the rod still drifts if air is lost. For sizing, treat roughly 34 N (0.6 of the 56.5 N push) as the realistic working force at 0.5 MPa, which lifts about 1.7 kg vertically with a 2:1 margin. The current-production replacement is ACEJ12X80 - confirm the ISO 21287 mounting dimensions before swapping, since the ACP is DIN-standard.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACEJ12X80-50SB (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 ACEJ12X80-50SB 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 ACPJ12X80-50SB Is Used
Semiconductor fixture clamping
The 30-80 mm trimmed extend range lets one cylinder serve multiple fixture heights on a 300 mm wafer-handling jig, with 56.5 N push at 0.5 MPa enough for light clamps.
Pick-and-place confirmation
With the -S magnet fitted, CMSE or DMSE switches confirm full extension on a small electronics assembly gantry where the 6 mm rod handles about 1.7 kg vertical lifts with margin.
Lab ejection station
A stop screw set at 45 mm gives repeatable part ejection from a test-rack nest, with the short ISO 21287-class body fitting where an ISO 15552 profile cylinder cannot.
Replacing the Airtac ACPJ Adjustable Compact Cylinder ACPJ12X80-50SB with the ACEJ12X80-50SB
Size both ways: if 56.5 N push at 0.5 MPa is marginal, step up to bore 16 (100.5 N push); if the load is light and space is very tight, bore 12 is already the smallest ACPJ bore, so consider the fixed-stroke ACP12X80 instead. Match FA/FB flange or LB foot hardware to the fixture, and remember the magnet here is the -S option this model carries - order plain codes without S only when no CMSE / DMSE switching is needed. This model is discontinued; ACEJ12X80 is the current drop-in successor in the same bore, stroke and force class, but verify ISO 21287 mounting dimensions first.
Replacement checklist
- ✓ Current-production ACE → ACEJ12X80-50SB
- ✓ 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 ACPJ12X80-50SB 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 -50 code is a 50 mm window: the stop screw trims the 80 mm stroke down to 30 mm. Operating pressure is 0.15-1.0 MPa (22-145 psi), speed 30-500 mm/s, port M5x0.8, rod 6 mm with male thread. The 80 mm stroke is a made-to-order size above the 50 mm standard maximum for bore 12.
No - the ACPJ family is discontinued. The current-production replacement is ACEJ12X80 (swap the P for an E), an ISO 21287 compact cylinder in the same bore, stroke and force class with a matching short body and mounting family. Because the ACP is DIN-standard, confirm the ISO 21287 mounting dimensions before ordering the swap. The fixed TPU bumpers, FA/FB flange and LB foot options carry over, and the magnet remains an -S option for CMSE / DMSE switches.
