This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACE100X45S, 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 ACP100X45S
The AirTAC ACP Compact Cylinder ACP100X45S is a double acting DIN-standard tight/compact air cylinder with a Ø100mm bore and 45mm stroke, 1/4" air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACE100X45S (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACP Compact Cylinder ACP100X45S
Double acting on both strokes, the ACP100X45S pairs a 100 mm bore with a short 45 mm stroke in a hard-anodized aluminium body that runs on a 25 mm S45C hard-chrome rod. At 0.5 MPa it pushes 3927 N and pulls 3681.6 N, rising to 5497.8 N push at 0.7 MPa, with a theoretical ceiling of 800.9 kgf at 1.0 MPa. The short ISO 21287-class body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into heavy press fixtures and gantries where a full-length body will not fit.
This unit carries the optional -S magnet, so CMSE or DMSE reed and solid-state switches can be clipped on for end-of-stroke signalling. Fixed TPU bumpers sit at both ends and the speed window is 30-500 mm/s at 0.15-1.0 MPa (22-145 psi). Note the ACP family is discontinued - the current-production direct is ACE100X45, and you should confirm the ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACE100X45S (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 ACE100X45S 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 ACP100X45S Is Used
Press die clamping
The 3927 N push at 0.5 MPa clamps heavy stamping dies on a 45 mm stroke, and the short body fits between press bolster and tooling where a full-length cylinder cannot.
Weld fixture position feedback
The -S magnet drives CMSE / DMSE switches at both ends of the 45 mm stroke, confirming clamp state before a robotic welder fires.
Replacing the Airtac ACP Compact Cylinder ACP100X45S with the ACE100X45S
At 100 mm bore this is the top of the ACP force ladder; if 3927 N at 0.5 MPa is more than the job needs, an 80 mm bore gives 2513 N push and a 63 mm bore 1558.6 N at the same pressure. Keep in mind a plain cylinder drifts when air is lost - add a rod lock or pilot check valve if the load must stay put. Female M16x1.5 rod thread and 1/4" PT ports suit large-flow circuits, and FA/FB flange, LB foot or CA/CB clevis mounting bolts to standard fixtures. The -S magnet on this model accepts CMSE / DMSE switches. Order ACE100X45 as the current replacement.
Replacement checklist
- ✓ Current-production ACE → ACE100X45S
- ✓ 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 ACP100X45S FAQ
At 0.5 MPa it pushes 3927 N and pulls 3681.6 N; at 0.7 MPa push is 5497.8 N and pull 5154.2 N; theoretical maximum is 800.9 kgf at 1.0 MPa. The model is discontinued - the current direct is ACE100X45 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 double-acting cylinder with a hard-anodized aluminium body, threaded aluminium covers and a 25 mm hard-chrome rod - about 50% shorter in mounting length than an ISO 15552 profile cylinder. Fixed TPU bumpers decelerate at each end. This -S version carries the magnet, so CMSE reed or DMSE solid-state switches mount directly for end-of-stroke detection; without -S there is no magnet.
