This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACEJ12X110-50S, 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 ACPJ12X110-50S
The AirTAC ACPJ Adjustable Compact Cylinder ACPJ12X110-50S is a double acting, double rod, adjustable stroke DIN-standard tight/compact air cylinder with a Ø12mm bore and 110mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACEJ12X110-50S (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPJ Adjustable Compact Cylinder ACPJ12X110-50S
The ACPJ12X110-50S is a double acting compact cylinder with an adjustable extend stroke: a stop screw trims the 110 mm stroke by up to 50 mm on site, giving a usable range of 60-110 mm. At 0.5 MPa the 12 mm bore delivers 56.5 N of push and 42.4 N of pull, rising to 79.2 N at 0.7 MPa. The 110 mm stroke exceeds the 50 mm maximum standard stroke for this bore, so it is a made-to-order build. This model is discontinued; the current-production replacement is the ACEJ12X110.
The short ISO 21287-class body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into slim fixtures and guarding where a full-length body cannot. The hard-anodized aluminium body carries an S45C hard-chrome rod, and fixed TPU bumpers sit at both ends. As an -S model it carries the optional magnet, so CMSE / DMSE reed or solid-state switches can be mounted for end-of-stroke sensing. A practical sizing rule: about 34 N (roughly 3 kg of vertical lift with a 2:1 margin) is realistic working force at 0.5 MPa, not the full 56.5 N rating.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACEJ12X110-50S (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 ACPJ12X110-50S Is Used
Small-part ejection from press dies
The 56.5 N push at 0.5 MPa is enough to strip light stamped brackets off a die, while the 60-110 mm adjustable range lets the operator tune the eject position without swapping cylinders.
Position-verified test fixtures
With the fitted -S magnet, CMSE or DMSE switches confirm the rod has reached the trimmed stop on a PCB or connector test rig, and the 30-500 mm/s speed range suits fast cycling.
Light gate-latch actuation on packaging lines
The 42.4 N pull at 0.5 MPa retracts a latch or diverter on a carton line, and the short body fits inside guarding where an ISO 15552 profile cylinder would be twice as long.
Replacing the Airtac ACPJ Adjustable Compact Cylinder ACPJ12X110-50S with the ACEJ12X110-50S
For light clamping and indexing in the 40-80 N range at 0.5 MPa, this 12 mm bore is the smallest AirTAC compact option; step up to the 16 mm bore (100.5 N push at 0.5 MPa) when loads approach 10 kg equivalent, or drop to a shorter window if you never need the full 60-110 mm range. Note that the stop screw only shortens the extend stroke - it is not a mid-stroke lock, so the piston still drifts if air is lost. Match FA/FB flange or LB foot mounting to your fixture, and order CMSE or DMSE switches alongside since the -S magnet is fitted here. Before ordering, confirm the ACEJ12X110 replacement's ISO 21287 mounting dimensions, as the ACP was DIN-standard.
Replacement checklist
- ✓ Current-production ACE → ACEJ12X110-50S
- ✓ 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 ACPJ12X110-50S FAQ
At 0.5 MPa it pushes 56.5 N and pulls 42.4 N; at 0.7 MPa those rise to 79.2 N and 59.4 N, with a theoretical maximum of 11.5 kgf at 1.0 MPa. The -50 code sets a 50 mm adjustment window, so the stop screw can trim the 110 mm extend stroke down to 60 mm. Operating pressure is 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), speed 30-500 mm/s, and the port is M5x0.8. The 110 mm stroke is a made-to-order length, since the standard maximum for a 12 mm bore is 50 mm.
It is a short-body compact cylinder with a hard-anodized aluminium body, an S45C hard-chrome piston rod and fixed TPU bumpers at both ends, saving about 50% of the mounting length of an ISO 15552 profile cylinder. This -S version carries the optional magnet, so CMSE reed or DMSE solid-state switches can be clamped on for end-of-stroke signals. The model itself is discontinued - the drop-in successor is the ACEJ12X110, so confirm ISO 21287 mounting dimensions before you swap.
