This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACE63X45B, 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 ACP63X45B
The AirTAC ACP Compact Cylinder ACP63X45B is a double acting DIN-standard tight/compact air cylinder with a Ø63mm bore and 45mm stroke, 1/8" air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACE63X45B (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACP Compact Cylinder ACP63X45B
A double acting compact cylinder with a 63 mm bore and 45 mm stroke, the ACP63X45B pushes with 1558.6 N and pulls with 1458.1 N at 0.5 MPa, rising to 2182.1 N at 0.7 MPa. The male rod thread (B code) on the 16 mm rod bolts straight to I/Y knuckles. Its short ISO 21287-class body saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight welding fixtures and press gantries where a full-length body cannot fit.
The hard-anodized aluminium body carries a fixed TPU bumper at each end that only softens end-of-travel contact - it never holds or brakes a load, so use a rod lock or pilot check valve if the load must stay put when air drops. Note that this model is discontinued: the current-production direct is the ACE63X45 (swap the P for an E), which matches the same bore, stroke and force class - confirm the ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACE63X45B (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 ACE63X45B 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 ACP63X45B Is Used
Welding fixture clamping
The 1558.6 N push at 0.5 MPa clamps steel brackets in automotive weld cells, and the 45 mm stroke clears the loader arm in a tight fixture plate.
Small press stamping
With about 95 kg of usable thrust at 0.5 MPa, this cylinder crimps terminals and stakes small electronics housings on bench-top press stations.
Pallet gate actuation
The 1458.1 N pull swings safety gates and diverters on warehouse conveyor lines, with the short body fitting inside the guard channel.
Replacing the Airtac ACP Compact Cylinder ACP63X45B with the ACE63X45B
At 0.5 MPa this bore delivers 1558.6 N push and 1458.1 N pull. If your jig needs less, the 50 mm bore gives 981.7 N push; if you need more, the 80 mm bore reaches 2513.3 N. The 45 mm stroke sits well inside the 250 mm maximum standard stroke for bore 63, so it is a catalogue item, not a made-to-order build. The B code gives a male rod thread and the port thread is PT; FA/FB flange, LB foot, CA/CB clevis, CR, SDB pivot and FTC brackets all bolt to the same face. The optional -S magnet code enables CMSE / DMSE switches - without it there is no magnet and no sensing. Order the ACE63X45 as the current replacement.
Replacement checklist
- ✓ Current-production ACE → ACE63X45B
- ✓ 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 ACP63X45B FAQ
At 0.5 MPa it pushes 1558.6 N and pulls 1458.1 N; at 0.7 MPa those figures rise to 2182.1 N and 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), speed 30-500 mm/s, and the 1/8" port depends only on the 63 mm bore.
This model is no longer in production. The current direct is the ACE63X45 (swap the P for an E), an ISO 21287 cylinder in the same bore, stroke and force class with the same short body and mounting family. Because the ACP was DIN-standard, confirm the ISO 21287 mounting dimensions before swapping. If you also need sensing, order the -S magnet code on the ACE so CMSE / DMSE switches can be fitted.
