This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACE63X40B, 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 ACP63X40B
The AirTAC ACP Compact Cylinder ACP63X40B is a double acting DIN-standard tight/compact air cylinder with a Ø63mm bore and 40mm stroke, 1/8" air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACE63X40B (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACP Compact Cylinder ACP63X40B
A double acting compact cylinder in the DIN-standard ACP series, the ACP63X40B pairs a 63 mm bore with a 40 mm stroke and a male rod thread (the B code). At 0.5 MPa it pushes 1558.6 N and pulls 1458.1 N, rising to 2182.1 N and 2041.3 N at 0.7 MPa. The short ISO 21287-class body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight machine frames and fixtures. Note this model is discontinued; the current-production successor is ACE63X40.
The hard-anodized aluminium body carries 1/8" ports, the 16 mm S45C hard-chrome rod runs 30-500 mm/s, and fixed TPU bumpers sit at both ends. The optional -S magnet enables CMSE / DMSE switches; without it no sensor can be fitted. FA/FB flange, LB foot and CA/CB clevis mountings bolt to the standard face.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACE63X40B (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 ACE63X40B 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 ACP63X40B Is Used
CNC fixture clamping
The 1558.6 N push at 0.5 MPa clamps steel housings in a machining fixture, and the short body fits between the jaws and the tombstone face.
Press-fit ejector
With about 79 kg of vertical lift equivalent at 0.5 MPa, the cylinder ejects finished bushings from a press die at the end of each cycle.
Packaging line diverters
A 40 mm stroke is enough to kick cartons between conveyor lanes, and the 30-500 mm/s speed range keeps the diverter in step with the line.
Replacing the Airtac ACP Compact Cylinder ACP63X40B with the ACE63X40B
At 63 mm bore this sits in the mid-heavy class: step down to ACP50 (981.7 N push at 0.5 MPa) for lighter clamping, or up to ACP80 (2513.3 N) when the load needs more margin. The 40 mm stroke is well inside the 250 mm maximum standard stroke for this bore. Remember the piston drifts when air is lost - add a rod lock or pilot check valve if the load must stay put. Order the -S code if you need CMSE / DMSE position sensing, and pick FA/FB flange, LB foot or CA/CB clevis to match the fixture. For new projects, specify ACE63X40 instead, confirming ISO 21287 mounting dimensions before the swap.
Replacement checklist
- ✓ Current-production ACE → ACE63X40B
- ✓ 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 ACP63X40B 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 1.5 MPa (215 psi) proof pressure, and speed runs 30-500 mm/s.
The current-production direct is ACE63X40 - swap the P for an E. It matches the same 63 mm bore, 40 mm stroke and force class in the ISO 21287 family, but confirm the ISO 21287 mounting dimensions before swapping, since the ACP was built to a DIN standard.
