This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACE63X50, 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 ACP63X50
The AirTAC ACP Compact Cylinder ACP63X50 is a double acting DIN-standard tight/compact air cylinder with a Ø63mm bore and 50mm stroke, 1/8" air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACE63X50 (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACP Compact Cylinder ACP63X50
The ACP63X50 is a double acting compact cylinder built to the DIN-standard short-body format, with a 63 mm bore, 50 mm stroke and a 16 mm hard-chrome S45C rod. At 0.5 MPa it pushes 1558.6 N and pulls 1458.1 N, rising to 2182.1 N push at 0.7 MPa. Its hard-anodized aluminium body with threaded aluminium covers saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight machine frames where a full-length cylinder cannot. Note this model is discontinued; the current-production successor is ACE63X50.
The fixed TPU bumper at each end only decelerates the piston; it never holds a load when air is lost, so add a rod lock or pilot check valve if the position must be kept. FA/FB flange, LB foot and CA/CB clevis mounts bolt to the ISO 21287 face. The optional -S magnet enables CMSE / DMSE switches; without -S there is no magnet.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACE63X50 (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 (Ø63mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 1559 N | 1458 N |
| 0.7 MPa | 2182 N | 2041 N |
| Max (@1.0 MPa) | 318 kgf | |
The ACE63X50 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 ACP63X50 Is Used
Clamping die pallets
With about 935 N of usable push at 0.5 MPa, the ACP63X50 clamps a 90-95 kg die pallet or machining fixture in a compact CNC cell where body length is limited.
Press-fit ejection
The 50 mm stroke and 2182.1 N push at 0.7 MPa suit ejecting bushings or bearings from assembly arbors on a small automated press station.
Conveyor gate diverters
Mounted with an LB foot bracket, the short body actuates diverter gates and stoppers on packaging conveyor lines, cycling at 30-500 mm/s.
Replacing the Airtac ACP Compact Cylinder ACP63X50 with the ACE63X50
For a 50 mm stroke in the 1500 N class at 0.5 MPa, the 63 mm bore is the right pick; drop to the 50 mm bore (981.7 N push) if the load is lighter, or step up to the 80 mm bore (2513.3 N push) for heavier tooling. The 50 mm stroke is well inside the 250 mm maximum standard stroke for this bore, so it is a catalogue item. Choose the female M10x1.5 rod thread as coded, or add B for a male thread. Order the -S variant if CMSE / DMSE position switches are needed. Since ACP is discontinued, specify ACE63X50 as the direct and confirm the ISO 21287 mounting dimensions before the swap.
Replacement checklist
- ✓ Current-production ACE → ACE63X50
- ✓ 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 ACP63X50 FAQ
At 0.5 MPa it pushes 1558.6 N and pulls 1458.1 N; at 0.7 MPa, 2182.1 N push and 2041.3 N pull. The theoretical maximum is 317.9 kgf at 1.0 MPa. Operating pressure is 0.15-1.0 MPa (22-145 psi) with a 1.5 MPa (215 psi) proof pressure, air filtered to 40 um, speed 30-500 mm/s and temperature -20 to +70 C.
The ACP family is out of production; the current direct is ACE63X50, the ISO 21287 successor with the same 63 mm bore, 50 mm stroke and force class. FA/FB flange, LB foot and CA/CB clevis brackets fit the ISO 21287 face, but confirm the mounting dimensions against the ACP (DIN-standard) footprint before swapping. The 1/8" port and M10x1.5 female rod thread carry over, and the -S magnet option enables CMSE / DMSE switches.
