This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACE40X65S, 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 ACP40X65S
The AirTAC ACP Compact Cylinder ACP40X65S is a double acting DIN-standard tight/compact air cylinder with a Ø40mm bore and 65mm stroke, 1/8" air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACE40X65S (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACP Compact Cylinder ACP40X65S
The ACP40X65S is a double acting DIN-standard compact cylinder with a 40 mm bore and 65 mm stroke, fitted with the optional -S magnet so CMSE / DMSE reed or solid-state switches can be mounted for end-of-stroke sensing. It pushes 628.3 N and pulls 571.8 N at 0.5 MPa, rising to 879.6 N on the extend stroke at 0.7 MPa, with a theoretical peak of 128.1 kgf at 1.0 MPa. Its hard-anodized aluminium body with an S45C hard-chrome rod runs on 0.15-1.0 MPa (22-145 psi) at 30-500 mm/s.
The short ISO 21287-class body saves about 50% of the mounting length of an ISO 15552 profile cylinder, which is why it was a favourite inside tight guarding, clamping fixtures and slide assemblies. A fixed TPU bumper at each end softens the end-of-travel contact but never locks the load - if the rod must hold position when air is lost, add a rod lock or pilot check valve. Note that this model is discontinued: the current-production replacement is ACE40X65, a direct in the same bore, stroke and force class, so confirm the ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACE40X65S (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 (Ø40mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 628 N | 572 N |
| 0.7 MPa | 880 N | 800 N |
| Max (@1.0 MPa) | 128 kgf | |
The ACE40X65S 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 ACP40X65S Is Used
Press-fit bushing insertion
A 65 mm stroke and 628.3 N push at 0.5 MPa seat small bushings into automotive bracket housings on a bench press fixture, with the -S magnet signalling full insertion to the PLC.
Pneumatic clamp on a CNC fixture
Mounted by FB flange beside a machining vise, the 40 mm bore holds aluminium workpieces against a stop; the short body fits where a full-length profile cylinder would foul the fixture.
Carton hold-down on a sealing head
The rod presses a flap flat while a tape head passes; CMSE switches on the -S magnet confirm the head is retracted before the conveyor advances.
Replacing the Airtac ACP Compact Cylinder ACP40X65S with the ACE40X65S
At 628.3 N push at 0.5 MPa, plan on roughly 377 N (about 38 kg of force) for real work rather than the full rating, which covers most clamping and pressing duties in the 40 mm class. If your load needs less, the 32 mm bore gives 402.1 N at 0.5 MPa in a smaller body; if it needs more, step up to the 50 mm bore at 981.7 N. The 65 mm stroke sits well inside the 200 mm standard range for this bore, and the female M8x1.25 rod thread takes standard I/Y knuckles. FA/FB flange, LB foot and CA/CB clevis mountings bolt to the same face. Since the ACP40X65S is discontinued, order ACE40X65 and verify the ISO 21287 mounting dimensions.
Replacement checklist
- ✓ Current-production ACE → ACE40X65S
- ✓ 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 ACP40X65S FAQ
At 0.5 MPa it pushes 628.3 N and pulls 571.8 N; at 0.7 MPa those rise to 879.6 N and 800.5 N, with a theoretical maximum of 128.1 kgf at 1.0 MPa. The ACP40X65S is discontinued. The current-production replacement is ACE40X65 (swap the P for an E), which matches the same 40 mm bore, 65 mm stroke and force class - confirm the ISO 21287 mounting dimensions before ordering.
The short ISO 21287-class body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into cramped jigs and slides. This model carries the optional -S magnet, so CMSE / DMSE reed or solid-state switches mount directly on the body for position feedback. Air supply is 0.15-1.0 MPa (22-145 psi), speed is 30-500 mm/s, and the fixed TPU bumpers at both ends soften end-of-travel contact without holding the load.
