This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACE80X120B, 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 ACP80X120B
The AirTAC ACP Compact Cylinder ACP80X120B is a double acting DIN-standard tight/compact air cylinder with a Ø80mm bore and 120mm stroke, 1/4" air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACE80X120B (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACP Compact Cylinder ACP80X120B
Double acting and DIN-standard compact, the ACP80X120B drives an 80 mm bore over a 120 mm stroke with a 20 mm male-thread rod (B code) and a 1/4" port. At 0.5 MPa it pushes 2513.3 N and pulls 2356.2 N; at 0.7 MPa those rise to 3518.6 N and 3298.7 N, with a theoretical ceiling of 512.6 kgf at 1.0 MPa. The 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, with fixed TPU bumpers at both ends.
Because the short ISO 21287-class body saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, this bore fits deep into press fixtures and gantry frames where a full-length body cannot. Note this model is discontinued - the current direct is ACE80X120, so confirm the ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACE80X120B (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 (Ø80mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 2513 N | 2356 N |
| 0.7 MPa | 3519 N | 3299 N |
| Max (@1.0 MPa) | 513 kgf | |
The ACE80X120B produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

Replacement mapping (swap P for E): ACP→ACE, ASP→ASE, ATP→ATE, ACPD→ACED, ACPJ→ACEJ. ACP-family: ACP (double acting), ASP / ATP (single acting push / pull), ACPD (double rod), ACPJ (double rod, adjustable stroke).
Where the Airtac ACP Compact Cylinder ACP80X120B Is Used
Press-fit bushing insertion
The 2513.3 N push at 0.5 MPa seats automotive bushings into control-arm housings on a 120 mm approach stroke, with the short body fitting inside the press head.
Clamping of machining fixtures
Holds aluminium gearbox castings against hard stops on a CNC milling line; the 20 mm male-thread rod (B code) accepts a custom clamp lever directly.
Replacing the Airtac ACP Compact Cylinder ACP80X120B with the ACE80X120B
For 120 mm of stroke at this force level, compare the 63 mm bore (1558.6 N push at 0.5 MPa) if the load is lighter, or step to the 100 mm bore (3927.0 N) for heavier clamping. The 120 mm stroke sits well inside the 300 mm maximum standard stroke for bore 80, so it is a catalogue item. The B code gives a male rod thread; omit B for a female rod end. FA/FB flange, LB foot and CA/CB clevis mount on the same face. If you need position feedback, order the -S variant to enable CMSE / DMSE switches - without -S there is no magnet. A plain cylinder drifts when air is lost, so add a rod lock or pilot check valve for held loads. Order ACE80X120 as the current replacement.
Replacement checklist
- ✓ Current-production ACE → ACE80X120B
- ✓ 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 ACP80X120B FAQ
At 0.5 MPa it pushes 2513.3 N and pulls 2356.2 N; at 0.7 MPa push is 3518.6 N and pull is 3298.7 N. The theoretical maximum is 512.6 kgf at 1.0 MPa. Operating range is 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), speed 30-500 mm/s, air filtered to 40 um, temperature -20 to +70 C.
Order ACE80X120, the current-production ISO 21287 successor: swap the P for an E and you get the same 80 mm bore, 120 mm stroke and force class in a matching short body. Confirm the ISO 21287 mounting dimensions against your fixture before swapping, since the ACP was built to the DIN standard. FA/FB flange, LB foot and CA/CB clevis options carry over in the ACE family.
