This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACE80X125SB, 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 ACP80X125SB
The AirTAC ACP Compact Cylinder ACP80X125SB is a double acting DIN-standard tight/compact air cylinder with a Ø80mm bore and 125mm stroke, 1/4" air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACE80X125SB (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACP Compact Cylinder ACP80X125SB
The ACP80X125SB is a double acting compact cylinder with an 80 mm bore and 125 mm stroke, built to the DIN-standard short-body format: hard-anodized aluminium body, S45C hard-chrome plated 20 mm rod, aluminium covers threaded onto the tube and a fixed TPU bumper at each end. At 0.5 MPa it pushes with 2513.3 N and pulls with 2356.2 N; at 0.7 MPa those figures rise to 3518.6 N and 3298.7 N, with a theoretical ceiling of 512.6 kgf at 1.0 MPa. Air supply is 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), speed 30-500 mm/s and temperature range -20 to +70 C on air filtered to 40 um.
Because the short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, this bore size slots into presses, clamping fixtures and gantries where a full-length body simply will not fit. The S code means the optional -S magnet is fitted, so CMSE or DMSE reed and solid-state switches can be mounted for end-of-stroke signalling, and the B code gives a male rod thread with a 1/4" PT port. Note that this model is discontinued: the current-production direct is the ISO 21287 ACE80X125 in the same bore, stroke and force class - confirm the ISO 21287 mounting dimensions before swapping, since the ACP is DIN-standard.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACE80X125SB (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 ACE80X125SB 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 ACP80X125SB Is Used
Pneumatic press and forming station
The 2513.3 N push at 0.5 MPa (3518.6 N at 0.7 MPa) suits a bench-top press that swages bushings into aluminium housings, with the 125 mm stroke clearing part loading by hand.
Fixture clamping on a CNC machining line
Clamps a cast gearbox housing against hard stops in a dedicated fixture, where the short body fits under the fixture lid and the CMSE switch on the fitted -S magnet confirms clamp completion to the PLC.
Replacing the Airtac ACP Compact Cylinder ACP80X125SB with the ACE80X125SB
Size the job both ways before committing: if 2513.3 N of push at 0.5 MPa is more than the task needs, an ACP63X125 delivers 1558.6 N in the same stroke; if the load demands more, step up to an ACP100X125 for 3927.0 N. Remember that a plain cylinder of this type drifts when air is lost or the valve centres - for a held vertical load, add a rod lock or pilot check valve rather than relying on the bumper. Match the mounting to the fixture with FA/FB flange, LB foot or CA/CB clevis brackets, and keep the -S magnet in the code if CMSE / DMSE switch feedback is planned. For new designs, order the ACE80X125 instead: this ACP model is discontinued and the ACE is the current ISO 21287 successor in the same force class.
Replacement checklist
- ✓ Current-production ACE → ACE80X125SB
- ✓ 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 ACP80X125SB FAQ
At 0.5 MPa it pushes with 2513.3 N and pulls with 2356.2 N; at 0.7 MPa the push is 3518.6 N and the pull 3298.7 N, with a theoretical maximum of 512.6 kgf at 1.0 MPa. Bore is 80 mm, stroke 125 mm, rod 20 mm, port 1/4" PT, rod end male thread, speed 30-500 mm/s, operating pressure 0.15-1.0 MPa (22-145 psi) and proof pressure 1.5 MPa (215 psi).
This model is no longer in production; the current-production replacement is the ACE80X125, the ISO 21287 successor in the same bore, stroke and force class. Confirm the ISO 21287 mounting dimensions before swapping, because the ACP follows the DIN-standard format. The -S magnet fitted on this unit accepts CMSE reed or DMSE solid-state switches for position feedback, and FA/FB flange, LB foot and CA/CB clevis brackets bolt to the mounting face. For outline dimensions not listed here, confirm from datasheet.
