This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACE50X75S, 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 ACP Compact Cylinder ACP50X75S
The AirTAC ACP Compact Cylinder ACP50X75S is a double acting DIN-standard tight/compact air cylinder with a Ø50mm bore and 75mm stroke, 1/8" air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACE50X75S (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACP Compact Cylinder ACP50X75S
A double acting compact cylinder in the DIN-standard ACP series, the ACP50X75S pairs a 50 mm bore with a 75 mm stroke and arrives with the optional -S magnet already fitted, so CMSE or DMSE reed and solid-state switches can be mounted for end-of-stroke sensing. At 0.5 MPa it pushes 981.7 N and pulls 881.2 N; at 0.7 MPa those figures rise to 1374.4 N and 1233.7 N, with a theoretical ceiling of 200.2 kgf at 1.0 MPa. The short ISO 21287-class body saves about 50% of the mounting length of an ISO 15552 profile cylinder, which is why it slots into tight jigs and guarding where a full-length body will not fit.
The hard-anodized aluminium body carries a fixed TPU bumper at each end that only decelerates the piston; it never holds a load, so if air is lost the rod drifts and a rod lock or pilot check valve is needed. This model is discontinued: the current-production direct is ACE50X75, same bore, stroke and force class - confirm the ISO 21287 mounting dimensions before swapping, since the ACP was built to a DIN standard.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACE50X75S (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 (Ø50mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 982 N | 881 N |
| 0.7 MPa | 1374 N | 1234 N |
| Max (@1.0 MPa) | 200 kgf | |
The ACE50X75S produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

Where the Airtac ACP Compact Cylinder ACP50X75S Is Used
Carton press-down station
With 981.7 N push at 0.5 MPa, the 50 mm bore seats flaps or presses inserts into shipping cartons on a packaging line, and the 75 mm stroke clears loading by hand between cycles.
Fixture clamping on a machining table
The short body fits inside fixture plates where a full-length profile cylinder would overhang, holding aluminium workpieces against stops with about 589 N of usable clamp force at 0.5 MPa.
Replacing the Airtac ACP Compact Cylinder ACP50X75S with the ACE50X75S
Size both ways before committing: a 40 mm bore gives 628.3 N push at 0.5 MPa, while stepping up to a 63 mm bore lifts the push to 1558.6 N - if your load sits near 600 N, the 50 mm bore with its 981.7 N push leaves a healthy margin. The 75 mm stroke sits well inside the 250 mm maximum standard stroke for this bore, so it is a catalogue item, not a made-to-order length. FA/FB flange, LB foot and CA/CB clevis mounts plus I/Y rod knuckles bolt to the same face, and the female M10x1.5 rod thread takes standard accessories. This unit is discontinued; order ACE50X75 as the current equivalent and verify the ISO 21287 mounting dimensions against your fixture.
Replacement checklist
- ✓ Current-production ACE → ACE50X75S
- ✓ Same bore / stroke / force class
- ✓ Confirm ISO 21287 mounting dimensions
- ✓ Port/thread type (PT / G)
- ✓ Add -S for magnet if you need sensors
Airtac ACP Compact Cylinder ACP50X75S FAQ
At 0.5 MPa the cylinder delivers 981.7 N push and 881.2 N pull; at 0.7 MPa that becomes 1374.4 N push and 1233.7 N pull. The theoretical maximum is 200.2 kgf at 1.0 MPa. Working pressure spans 0.15-1.0 MPa (22-145 psi) with a 1.5 MPa (215 psi) proof rating, speed runs 30-500 mm/s, and the rod is 16 mm with a female M10x1.5 thread on a 1/8" port.
Yes, the ACP family is out of production. The current direct is ACE50X75, the ISO 21287 successor with the same 50 mm bore, 75 mm stroke and force class. Because the ACP was built to a DIN standard, confirm the ISO 21287 mounting dimensions against your fixture before swapping. On sensing: this ACP carries the optional -S magnet, and the ACE equivalent accepts CMSE / DMSE reed or solid-state switches the same way - order the -S code on the ACE if you need the magnet fitted.
