This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACEJ12X10-10S, the same code under the new prefix. 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 ACPJ12X10-10S
The AirTAC ACPJ Adjustable Compact Cylinder ACPJ12X10-10S is a double acting, double rod, adjustable stroke DIN-standard tight/compact air cylinder with a Ø12mm bore and 10mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACEJ12X10-10S (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPJ Adjustable Compact Cylinder ACPJ12X10-10S
This discontinued ACPJ12X10-10S is a double acting compact cylinder with an adjustable extend stroke: the -10 code gives a 10 mm trim window, so a stop screw shortens the 10 mm stroke on site to any usable range from 0 to 10 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 peak of 11.5 kgf at 1.0 MPa. Air runs at 0.15-1.0 MPa (22-145 psi) and rod speed from 30-500 mm/s.
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 fixtures and guarding where a full-length body cannot. In practice, plan on about 34 N of real work at 0.5 MPa (roughly 60% of the push rating), which lifts about 3 kg vertically - halve that for a 2:1 margin and match parts under 1.5 kg. The fitted -S magnet accepts CMSE / DMSE switches, the fixed TPU bumpers decelerate at both ends, and the current drop-in is the ACEJ12X10 - confirm ISO 21287 mounting dimensions before swapping, since the ACP is DIN-standard.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACEJ12X10-10S (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 | Force (both ways) |
|---|---|
| 0.5 MPa | 42 N |
| 0.7 MPa | 59 N |
| Max (@1.0 MPa) | 9 kgf |
ACPJ is double-rod: the rear rod that carries the stroke adjuster exits the rear cover, so both piston faces lose rod area. The rod-side (annular) area is used for both directions (conservative).

Where the Airtac ACPJ Adjustable Compact Cylinder ACPJ12X10-10S Is Used
Micro part presence checks
The 10 mm trimmed stroke and fitted magnet let a CMSE switch confirm a small electronic component has seated in a test nest, cycling at up to 500 mm/s.
Compact ejection in assembly heads
With 56.5 N push at 0.5 MPa, the 12 mm bore ejects light plastic caps or pins from a fixture on a dial-table machine where a longer body will not fit.
Adjustable clamping of small housings
The 0-10 mm stop-screw window lets a jig builder dial in the exact clamp travel for sensor housings, with the TPU bumper softening each end stop.
Replacing the Airtac ACPJ Adjustable Compact Cylinder ACPJ12X10-10S with the ACEJ12X10-10S
At 12 mm bore this is the smallest force class in the range: 56.5 N push at 0.5 MPa. Step up to the 16 mm bore for 100.5 N push at the same pressure, or drop to it from the 20 mm bore (157.1 N) when space is tight. Note the adjuster is a mechanical end stop for the extend stroke only - on air loss the piston still drifts, so do not rely on it to hold a load. Female M3x0.5 rod thread, PT ports, FA/LB mounting, and the optional -S magnet (fitted on this model) for CMSE / DMSE switches. Discontinued: order the ACEJ12X10 as the current-production equivalent.
Replacement checklist
- ✓ Current-production ACE → ACEJ12X10-10S
- ✓ 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 ACPJ12X10-10S 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, with a theoretical maximum of 11.5 kgf at 1.0 MPa. The 12 mm bore has a 6 mm rod, M5x0.8 ports, M3x0.5 female rod thread, a 10 mm stroke with a 10 mm adjustment window, operating pressure 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), -20 to +70 C, speed 30-500 mm/s, and fixed TPU bumpers both ends. This model is discontinued - the ACEJ12X10 is the current replacement.
An external stop screw trims the extend stroke anywhere within the ordered 10 mm window, so the effective range is 0-10 mm; it cannot lengthen the stroke past 10 mm. The -S code on this model means the magnet is fitted, so CMSE / DMSE reed or solid-state switches can be mounted directly on the hard-anodized aluminium body. Before ordering, confirm the ISO 21287 mounting dimensions of the ACEJ12X10 successor against your fixture.
