This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACE100X250B, 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 ACP100X250B
The AirTAC ACP Compact Cylinder ACP100X250B is a double acting DIN-standard tight/compact air cylinder with a Ø100mm bore and 250mm stroke, 1/4" air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACE100X250B (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACP Compact Cylinder ACP100X250B
The ACP100X250B is a discontinued DIN-standard compact cylinder that runs double acting: air both extends and retracts its 25 mm rod. At the 100 mm bore it 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 B code gives a male rod thread and the 1/4" port suits the large bore. Its hard-anodized aluminium body with an S45C hard-chrome rod keeps the short ISO 21287-class footprint, saving roughly 50% of the mounting length of an ISO 15552 profile cylinder - ideal when a 250 mm stroke must fit inside a press frame or gantry that a full-length body cannot.
A fixed TPU bumper pads both ends of travel; it never holds a load, so use a rod lock or pilot check valve where position must be kept on air loss. This model carries no magnet (the optional -S code adds one for CMSE / DMSE switches). Production has ended: the current direct is the ACE100X250 in the same bore, stroke and force class - confirm the ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACE100X250B (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 ACE100X250B 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 ACP100X250B Is Used
Heavy press-frame clamping
The 3927 N push at 0.5 MPa (about 240 kg of vertical work) stakes large fixture clamps on a machining centre table, with the short body fitting between the jaws where a full-length cylinder will not.
Bottle-line gate actuator
On a filling line, the 1/4" port and 30-500 mm/s speed band drive a heavy gate or diverter, with the fixed TPU bumper softening each end of the 250 mm travel.
Replacing the Airtac ACP Compact Cylinder ACP100X250B with the ACE100X250B
Size against neighbours: the 80 mm bore pushes 2513 N at 0.5 MPa and suits lighter clamp loads, while this 100 mm bore nearly doubles that to 3927 N - step up only if your fixture can absorb the larger body. The 250 mm stroke sits within the 300 mm maximum standard stroke for this bore, so no made-to-order length is needed. Match the male rod thread (B code) to an I or Y rod knuckle on the ISO 21287 face; FA/FB flange, LB foot, CA/CB clevis, CR, SDB pivot and FTC brackets all bolt on. If switches are needed, order the -S variant instead. For new builds, specify the ACE100X250 - it is the current-production successor in this force class.
Replacement checklist
- ✓ Current-production ACE → ACE100X250B
- ✓ 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 ACP100X250B FAQ
At 0.5 MPa it pushes 3927 N and pulls 3681.6 N; at 0.7 MPa those rise to 5497.8 N and 5154.2 N. The theoretical maximum is 800.9 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. In practice budget about 2356 N of usable force at 0.5 MPa, roughly a 240 kg vertical lift.
The body is a short hard-anodized aluminium design with aluminium covers and an S45C hard-chrome rod, saving about 50% of the mounting length of an ISO 15552 profile cylinder. A fixed TPU bumper pads both ends but never locks a load - add a rod lock or pilot check valve if the position must hold. The rod end is male thread (B code) with a PT port thread; the magnet is the optional -S code for CMSE / DMSE switches, not fitted here. The ACP100X250B is discontinued - the ACE100X250 is the current direct, so confirm ISO 21287 mounting dimensions before ordering.
