This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACEJ12X80-100, 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 ACPJ12X80-100
The AirTAC ACPJ Adjustable Compact Cylinder ACPJ12X80-100 is a double acting, double rod, 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 ACEJ12X80-100 (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPJ Adjustable Compact Cylinder ACPJ12X80-100
This compact AirTAC cylinder is double acting, with air extending and retracting the 6 mm rod, and its -100 code gives a 100 mm adjustment window: a stop screw trims the extend stroke on site anywhere from 0 up to the full 80 mm. At 0.5 MPa it pushes 56.5 N and pulls 42.4 N, rising to 79.2 N / 59.4 N at 0.7 MPa. The 80 mm stroke exceeds the 50 mm standard limit for a 12 mm bore, so this unit is made to order.
The short ISO 21287-class body saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, which is why it suits tight jigs and guarded stations. In practice, plan on about 34 N of usable push at 0.5 MPa, which lifts roughly 2.9 kg vertically with a 2:1 margin. Note the model is discontinued: the current-production drop-in is ACEJ12X80, so confirm ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACEJ12X80-100 (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 ACPJ12X80-100 Is Used
Micro jig clamping
The 56.5 N push at 0.5 MPa clamps small aluminium or plastic workpieces in drilling and milling jigs, with the stop screw trimming the stroke to the fixture depth.
Small-part ejection
On electronics assembly lines the rod knocks light components off chutes or nests; the female M3x0.5 thread accepts a knuckle for angled pushes.
Guarded slide feed
Inside tight machine guards, the short body feeds small trays or fixtures where a full-length profile cylinder would not fit, running 30-500 mm/s.
Replacing the Airtac ACPJ Adjustable Compact Cylinder ACPJ12X80-100 with the ACEJ12X80-100
At 12 mm bore you get 56.5 N push at 0.5 MPa; step up to the 16 mm bore for 100.5 N or down only if the load is under about 34 N. The 80 mm stroke is non-standard for this bore (50 mm max standard), so order it as a made-to-order item. This version has no magnet, so no CMSE / DMSE switch can be fitted; choose the -S code if sensing is needed. FA/FB flange and LB foot mountings bolt to the same face. Since ACPJ is discontinued, spec ACEJ12X80 as the replacement and verify the ISO 21287 hole pattern.
Replacement checklist
- ✓ Current-production ACE → ACEJ12X80-100
- ✓ 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 ACPJ12X80-100 FAQ
Push is 56.5 N and pull 42.4 N at 0.5 MPa; at 0.7 MPa it reaches 79.2 N push and 59.4 N pull, with a theoretical maximum of 11.5 kgf at 1.0 MPa. Operating pressure is 0.15-1.0 MPa (22-145 psi), proof 1.5 MPa (215 psi), speed 30-500 mm/s, port M5x0.8, rod thread M3x0.5 female. The 80 mm stroke is a made-to-order length above the 50 mm standard for this bore.
The -100 window lets a stop screw shorten the extend stroke anywhere between 0 and 80 mm on site; it is a mechanical end stop only, so the piston still drifts if air is lost. Fixed TPU bumpers decelerate at both ends. The ACPJ family is discontinued; ACEJ12X80 is the current ISO 21287 drop-in successor in the same force class - confirm its mounting dimensions before converting.
