This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACE100X25B, 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 ACP100X25B
The AirTAC ACP Compact Cylinder ACP100X25B is a double acting DIN-standard tight/compact air cylinder with a Ø100mm bore and 25mm stroke, 1/4" air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACE100X25B (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACP Compact Cylinder ACP100X25B
A double acting compact cylinder in the 100 mm bore class, the ACP100X25B delivers 3927 N push and 3681.6 N pull at 0.5 MPa, rising to 5497.8 N at 0.7 MPa, with a theoretical peak of 800.9 kgf at 1.0 MPa. The 25 mm stroke keeps the body short, and the hard-anodized aluminium construction with an S45C hard-chrome rod shrugs off shop-floor wear. Air supply runs 0.15-1.0 MPa (22-145 psi) with a 1.5 MPa (215 psi) proof rating, and rod speed spans 30-500 mm/s.
The short ISO 21287-class body saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into dense press fixtures and gantries. Fixed TPU bumpers decelerate the piston at both ends. Note this model is discontinued; the current-production direct is the ACE100X25, so confirm ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACE100X25B (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 (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3927 N | 3682 N |
| 0.7 MPa | 5498 N | 5154 N |
| Max (@1.0 MPa) | 801 kgf | |
The ACE100X25B 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 ACP100X25B Is Used
Heavy press fixture
The 3927 N push at 0.5 MPa (about 5497.8 N at 0.7 MPa) clinches, stakes and swages steel brackets in a 25 mm stroke press jig.
Automotive weld cell clamp
Short-stroke 100 mm bore clamping of body panels and fixtures, with the compact body fitting between robot reach envelopes and weld guns.
Pallet gate actuator
Swinging or lifting heavy line gates and stops on a packaging conveyor, where the 1/4" port keeps flow up for 30-500 mm/s cycling.
Replacing the Airtac ACP Compact Cylinder ACP100X25B with the ACE100X25B
At 100 mm bore this is the largest size in the family: 3927 N push at 0.5 MPa versus 1558.6 N for a 63 mm bore, while the 80 mm bore offers 2513.3 N if you need a step down. The 25 mm stroke suits short-throw clamping and pressing. The B code gives a male rod thread (M16x1.5 female is the alternative), and the 1/4" port feeds the big bore. Without the -S code there is no magnet, so order ACP100X25SB if you need CMSE or DMSE switches. Remember the piston drifts when air is lost - add a rod lock or pilot check valve for held loads. This model is discontinued; the ACE100X25 is the current replacement, and ISO 21287 mounting dimensions should be confirmed before the swap.
Replacement checklist
- ✓ Current-production ACE → ACE100X25B
- ✓ 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 ACP100X25B FAQ
At 0.5 MPa it pushes 3927 N and pulls 3681.6 N; at 0.7 MPa that rises to 5497.8 N push and 5154.2 N pull, with a theoretical maximum of 800.9 kgf at 1.0 MPa. The model is discontinued - the current-production replacement is the ACE100X25, a direct in the same bore, stroke and force class. Confirm the ISO 21287 mounting dimensions before swapping, since the ACP was built to a DIN standard.
It is a compact short-body cylinder with a hard-anodized aluminium body, threaded aluminium covers, an S45C hard-chrome rod and fixed TPU bumpers at both ends, saving about 50% of the mounting length of an ISO 15552 profile cylinder. Sensing requires the optional -S magnet: order ACP100X25SB and CMSE or DMSE switches can ride the body; without the -S code there is no magnet and no switch mounting.
