This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACE63X50B, 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 ACP63X50B
The AirTAC ACP Compact Cylinder ACP63X50B 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 ACE63X50B (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACP Compact Cylinder ACP63X50B
A double acting compact cylinder built to the DIN-standard short-body format, the ACP63X50B pairs a 63 mm bore with a 50 mm stroke and a male rod thread (B code). At 0.5 MPa it pushes 1558.6 N and pulls 1458.1 N; at 0.7 MPa those rise to 2182.1 N and 2041.3 N, with a theoretical ceiling of 317.9 kgf at 1.0 MPa. The hard-anodized aluminium body carries a 16 mm S45C hard-chrome rod, and fixed TPU bumpers sit at both ends. Air supply is 0.15-1.0 MPa (22-145 psi), speed range 30-500 mm/s, fluid air filtered to 40 um.
The short ISO 21287-class body saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight clamping fixtures and gantry frames. Note this unit ships without a magnet: the optional -S code is what enables CMSE / DMSE switches. The ACP family is discontinued, and the current-production direct is ACE63X50 - confirm ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACE63X50B (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 ACE63X50B 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 ACP63X50B Is Used
CNC fixture clamping
The 1558.6 N push at 0.5 MPa clamps aluminium housings in machining fixtures, and the short body fits where a full-length profile cylinder cannot.
Press-fit assembly stations
With about 2182.1 N at 0.7 MPa, this bore presses bushings and dowel pins into small castings on bench-top assembly cells.
Packaging line diverters
A 50 mm stroke with 30-500 mm/s speed flips guide rails and pusher arms on bottling and carton conveyors, with CMSE / DMSE switches when the -S magnet is ordered.
Replacing the Airtac ACP Compact Cylinder ACP63X50B with the ACE63X50B
At 63 mm bore you sit between the 50 mm (981.7 N push at 0.5 MPa) and the 80 mm (2513.3 N push at 0.5 MPa), so step down if 981.7 N covers your load or step up if you need more than 1558.6 N. Remember a plain ACP drifts when air is lost - add a rod lock or pilot check valve if the load must stay put. FA/FB flange, LB foot and CA/CB clevis mounts bolt to the same face, and the optional -S magnet is required for CMSE / DMSE switch feedback. Order ACE63X50 as the current replacement and verify ISO 21287 mounting dimensions.
Replacement checklist
- ✓ Current-production ACE → ACE63X50B
- ✓ 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 ACP63X50B FAQ
Push is 1558.6 N and pull 1458.1 N at 0.5 MPa; at 0.7 MPa push is 2182.1 N and pull 2041.3 N; theoretical maximum is 317.9 kgf at 1.0 MPa. Bore 63 mm, stroke 50 mm, rod 16 mm, port 1/8" PT, male rod thread (B code), operating pressure 0.15-1.0 MPa (22-145 psi), speed 30-500 mm/s, temperature -20 to +70 C. The model is discontinued; ACE63X50 is the current replacement.
The compact aluminium body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it fits shallow jigs and guard zones. Fixed TPU bumpers at both ends simply decelerate the piston at end of travel - they do not adjust, and they never hold a load when air drops. For position holding add a rod lock or pilot check valve, and for switch feedback order the optional -S magnet with CMSE / DMSE sensors.
