This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACEJ12X70-10B — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACEJ12X70-10B 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 ACPJ12X70-10B
The AirTAC Airtac ACPJ Adjustable Compact Cylinder ACPJ12X70-10B is a double acting, adjustable stroke DIN-standard tight/compact air cylinder with a Ø12mm bore and 70mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACEJ12X70-10B (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPJ Adjustable Compact Cylinder ACPJ12X70-10B
The ACPJ12X70-10B is a double acting compact cylinder with an adjustable extend stroke: a stop screw trims the 70 mm stroke by up to 10 mm, giving a usable range of 60-70 mm on site. This 12 mm bore unit 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 peak of 11.5 kgf at 1.0 MPa. The 70 mm stroke exceeds the 50 mm standard maximum for bore 12, so it is a made-to-order build. Note this model is discontinued; the current-production replacement is ACEJ12X70.
The short ISO 21287-class body saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into slim fixtures, small gantries and guarded stations where a full-length body cannot. In practice, plan on about 34 N of usable push at 0.5 MPa (roughly 60% of the rating), which means this cylinder lifts about 2.9 kg vertically with a 2:1 margin - enough for small covers, sensors or light plastic parts. The rod end is male thread (B code) with a PT port thread, and the fixed TPU bumper at each end simply decelerates the piston; it never locks or holds a load.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACEJ12X70-10B (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 ACEJ12X70-10B 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 ACPJ12X70-10B Is Used
Small-parts ejection in plastic molding
The 56.5 N push at 0.5 MPa and 60-70 mm adjustable range suit nudging finished caps or connectors off a mold nest, with the male rod thread taking a custom ejector tip.
Light gate actuation on packaging lines
A 2.9 kg vertical-lift equivalent handles flipping small test flaps or diverting lightweight cartons, and the short body fits beside tight conveyor guarding.
Sample press in lab automation
About 34 N of working force at 0.5 MPa presses microplate seals or dip-test probes, and the 10 mm stop screw lets technicians fine-tune the press depth without shims.
Replacing the Airtac ACPJ Adjustable Compact Cylinder ACPJ12X70-10B with the ACEJ12X70-10B
Bore 12 is the smallest in the ACPJ range, so if your load needs more than about 34 N of working force, step up to bore 16 (100.5 N push at 0.5 MPa) or bore 20 (157.1 N). Match the -10 window only when your jig needs less than 10 mm of stroke trimming; wider windows of 20-100 mm exist for other variants. This unit has no magnet (no S code), so no CMSE or DMSE switch can be fitted - order an -S version if sensing is required. FA flange or LB foot mounts bolt to the standard face. Before ordering, remember the ACPJ is discontinued: specify ACEJ12X70 and confirm the ISO 21287 mounting dimensions against your fixture.
Replacement checklist
- ✓ Current-production ACE → ACEJ12X70-10B
- ✓ 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 ACPJ12X70-10B 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 -10 code gives a 10 mm adjustment window, so the 70 mm extend stroke can be trimmed anywhere from 60 to 70 mm. Operating pressure is 0.15-1.0 MPa (22-145 psi), speed 30-500 mm/s, with a fixed TPU bumper at both ends. The 70 mm stroke is made to order because the bore 12 standard maximum is 50 mm.
The hard-anodized aluminium body follows the short DIN-standard compact format, saving about 50% of the mounting length of an ISO 15552 profile cylinder, with FA flange or LB foot mounting and an M5x0.8 port. This ACPJ12X70-10B is discontinued: order the ACEJ12X70, which swaps the P for an E and matches the same bore, stroke and force class as the current ISO 21287 drop-in. Confirm the ISO 21287 mounting dimensions against your fixture before swapping, and add the -S code if you need the optional magnet for CMSE or DMSE switches.
