This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACEJ12X90-10B, 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 ACPJ12X90-10B
The AirTAC ACPJ Adjustable Compact Cylinder ACPJ12X90-10B is a double acting, double rod, adjustable stroke DIN-standard tight/compact air cylinder with a Ø12mm bore and 90mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACEJ12X90-10B (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPJ Adjustable Compact Cylinder ACPJ12X90-10B
Double acting and adjustable, the ACPJ12X90-10B is a discontinued DIN-standard compact cylinder with a 12 mm bore and a made-to-order 90 mm stroke. At 0.5 MPa it pushes 56.5 N and pulls 42.4 N, rising to 79.2 N push at 0.7 MPa, with a theoretical peak of 11.5 kgf at 1.0 MPa. The -10 code gives a 10 mm adjustment window: a stop screw trims the extend stroke on site, so the usable range is 80-90 mm. Air filtered to 40 um, 0.15-1.0 MPa (22-145 psi), speed 30-500 mm/s.
The hard-anodized aluminium body with an S45C hard-chrome 6 mm rod saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight fixtures. The male rod thread (B code) suits external knuckles. Plan on roughly 34 N of usable push at 0.5 MPa, which lifts about 3 kg vertically with a 2:1 margin. This model is discontinued; the current-production drop-in is ACEJ12X90, so confirm ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACEJ12X90-10B (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 | 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 ACPJ12X90-10B Is Used
Small-part ejection on assembly fixtures
The 34 N usable push at 0.5 MPa is enough to kick light plastic or stamped parts off a nest, and the 80-90 mm trimmed stroke clears shallow dies.
Clamp-and-confirm test stations
With the optional -S magnet and CMSE / DMSE switches, the 90 mm stroke confirms part seating on electronics inspection benches.
Low-force press fitting of bushings
79.2 N at 0.7 MPa suits pressing small nylon spacers into housings where a larger bore would damage the part.
Replacing the Airtac ACPJ Adjustable Compact Cylinder ACPJ12X90-10B with the ACEJ12X90-10B
Size both ways: if 56.5 N push at 0.5 MPa is more than your jig needs, the 12 mm is already the smallest bore; if you need roughly 100.5 N, step up to the 16 mm. The stop screw is a mechanical end stop for the extend stroke, not a mid-stroke lock, so the piston still drifts on air loss. The B code gives a male rod thread; the optional -S magnet enables CMSE / DMSE switches, but without it no sensor can be fitted. Order the ACEJ12X90 as the current replacement.
Replacement checklist
- ✓ Current-production ACE → ACEJ12X90-10B
- ✓ 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 ACPJ12X90-10B FAQ
At 0.5 MPa it pushes 56.5 N and pulls 42.4 N; at 0.7 MPa, 79.2 N push and 59.4 N pull. The theoretical maximum is 11.5 kgf at 1.0 MPa. Operating range is 0.15-1.0 MPa (22-145 psi) with a 1.5 MPa (215 psi) proof pressure, and speed runs 30-500 mm/s. The 90 mm stroke is a made-to-order length above the 50 mm standard maximum for this bore.
The -10 code is a 10 mm window: an external stop screw shortens the 90 mm extend stroke on site to any length from 80 to 90 mm; it cannot lengthen past 90 mm. Fixed TPU bumpers at both ends absorb end-of-travel contact. The model is discontinued, so order the ACEJ12X90 as the drop-in and confirm ISO 21287 mounting dimensions first, since the ACPJ is DIN-standard.
