This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACE40X80S, 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 ACP40X80S
The AirTAC ACP Compact Cylinder ACP40X80S is a double acting DIN-standard tight/compact air cylinder with a Ø40mm bore and 80mm stroke, 1/8" air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACE40X80S (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACP Compact Cylinder ACP40X80S
Double acting compact cylinder with a 40 mm bore and 80 mm stroke, the ACP40X80S pushes with 628.3 N and pulls with 571.8 N at 0.5 MPa, rising to 879.6 N on the extend stroke at 0.7 MPa. Its short ISO 21287-class body saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight guarding and fixture plates. The -S code means the magnet is fitted, so CMSE or DMSE reed and solid-state switches can be clipped on for end-of-stroke sensing.
The hard-anodized aluminium body carries a fixed TPU bumper at each end and an S45C hard-chrome rod with a female M8x1.25 thread. Note this model is discontinued: the current-production direct is ACE40X80, so confirm ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACE40X80S (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 ACE40X80S 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 ACP40X80S Is Used
CNC fixture clamping
The 628.3 N push at 0.5 MPa clamps aluminium housings in a machining fixture, and the short body fits between the vise jaw and the tombstone face.
Gated pallet transfer
With the -S magnet fitted, CMSE switches confirm extend and retract on an 80 mm gate stroke over a conveyor lane, cycling at 30-500 mm/s.
Replacing the Airtac ACP Compact Cylinder ACP40X80S with the ACE40X80S
At 40 mm bore you sit mid-range: a 32 mm bore gives 402.1 N push at 0.5 MPa if your load is lighter, while a 50 mm bore delivers 981.7 N for heavier clamping. The 80 mm stroke is well inside the 200 mm maximum standard stroke for this bore, so it is a catalog item. If your valve centres or air drops, the rod will drift - add a rod lock or pilot check valve to hold a load. FA/FB flange, LB foot and CA/CB clevis mounts suit the same fixtures, and the ACE40X80 is the current replacement to order.
Replacement checklist
- ✓ Current-production ACE → ACE40X80S
- ✓ 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 ACP40X80S FAQ
At 0.5 MPa the 40 mm bore pushes 628.3 N and pulls 571.8 N; at 0.7 MPa that rises to 879.6 N push and 800.5 N pull. The theoretical maximum is 128.1 kgf at 1.0 MPa. Operating range is 0.15-1.0 MPa (22-145 psi) with 1.5 MPa (215 psi) proof pressure, air filtered to 40 um, speed 30-500 mm/s and -20 to +70 C. For real work, budget about 377 N (roughly 38 kg of force) at 0.5 MPa.
The short ISO 21287-class body saves about 50% of the mounting length of an ISO 15552 profile cylinder, and FA/FB flange, LB foot and CA/CB clevis brackets bolt to the standard face. The -S code on this model means the magnet is fitted, so CMSE or DMSE switches can be mounted for position feedback; the fixed TPU bumpers only soften end-of-stroke contact. The ACP family is discontinued - order ACE40X80 as the current direct and confirm the ISO 21287 mounting dimensions first.
