This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACE63X120B, 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 ACP63X120B
The AirTAC ACP Compact Cylinder ACP63X120B is a double acting DIN-standard tight/compact air cylinder with a Ø63mm bore and 120mm stroke, 1/8" air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACE63X120B (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACP Compact Cylinder ACP63X120B
The ACP63X120B is a double acting DIN-standard compact cylinder with a 63 mm bore and 120 mm stroke, driving a 16 mm S45C hard-chrome rod from a hard-anodized aluminium body. At 0.5 MPa it pushes 1558.6 N and pulls 1458.1 N, rising to 2182.1 N on the extend stroke at 0.7 MPa. The short ISO 21287-class body saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight gantries and machine frames. The B code gives a male rod thread, and the port is 1/8" because port size depends only on the bore.
This model is discontinued; the current-production direct is the ACE63X120, which matches the same bore, stroke and force class - confirm the ISO 21287 mounting dimensions before swapping. Fixed TPU bumpers at both ends simply decelerate the piston, so a lost load needs a rod lock or pilot check valve. Mounting brackets FA/FB, LB, CA/CB bolt to the standard face, and the optional -S magnet enables CMSE / DMSE switches.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACE63X120B (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 ACE63X120B 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 ACP63X120B Is Used
Clamping fixtures on CNC machining lines
With 1558.6 N push at 0.5 MPa, the 63 mm bore clamps steel housings in dedicated fixtures; the short body fits where a full-length profile cylinder cannot.
Packaging machine push-off stations
The 120 mm stroke ejects cartons or trays from conveyor lanes at 30-500 mm/s, with the 1/8" port keeping plumbing compact on multi-station machines.
Replacing the Airtac ACP Compact Cylinder ACP63X120B with the ACE63X120B
At 63 mm bore this sits in the mid-heavy class: 1558.6 N push at 0.5 MPa. If your load needs under 981.7 N, the ACP50 saves space and air; if it needs up to 2513.3 N, step to the 80 mm bore. The 120 mm stroke is within the 250 mm standard range for this bore, so no made-to-order stroke is required. Choose the B male rod thread where an external knuckle is threaded on, or the blank female M10x1.5 rod thread for I/Y accessories. Order the -S code if you need CMSE / DMSE position switches - without it there is no magnet. Since ACP is discontinued, spec the ACE63X120 as the current replacement and verify the ISO 21287 mounting footprint.
Replacement checklist
- ✓ Current-production ACE → ACE63X120B
- ✓ 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 ACP63X120B FAQ
At 0.5 MPa it pushes 1558.6 N and pulls 1458.1 N; at 0.7 MPa it pushes 2182.1 N and pulls 2041.3 N. The theoretical maximum is 317.9 kgf at 1.0 MPa. Operating range is 0.15-1.0 MPa (22-145 psi) with 1.5 MPa (215 psi) proof pressure, running on air filtered to 40 um at 30-500 mm/s.
No - the ACP family is discontinued. The current-production replacement is the ACE63X120 (swap the P for an E), an ISO 21287 compact cylinder in the same bore, stroke and force class. Confirm the ISO 21287 mounting dimensions before the swap, since the ACP was built to the DIN standard. FA/FB flange, LB foot and CA/CB clevis brackets are available on the ACE, and the optional -S magnet supports CMSE / DMSE switches.
