This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACE100X325SB, 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 ACP100X325SB
The AirTAC ACP Compact Cylinder ACP100X325SB is a double acting DIN-standard tight/compact air cylinder with a Ø100mm bore and 325mm stroke, 1/4" air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACE100X325SB (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACP Compact Cylinder ACP100X325SB
A double acting compact cylinder with a 100 mm bore and a made-to-order 325 mm stroke, the ACP100X325SB delivers 3927 N on extension and 3681.6 N on retraction at 0.5 MPa, rising to 5497.8 N push at 0.7 MPa. The hard-anodized aluminium body keeps the mounting length roughly 50% shorter than an ISO 15552 profile cylinder, so a long-stroke axis still fits inside a tight press frame or gantry. The S code means the optional -S magnet is fitted, so CMSE or DMSE reed and solid-state switches can be clipped on for end-of-stroke signalling.
The B code gives a male rod thread on the 25 mm rod, with a 1/4" port and PT thread on the port side. Fixed TPU bumpers at both ends absorb end-of-travel impact, but they do not hold a load: when air is lost the piston drifts, so add a rod lock or pilot check valve where a raised load must stay put. Note that ACP is discontinued; the current-production direct is ACE100X325 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 ACE100X325SB (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 ACE100X325SB 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 ACP100X325SB Is Used
Stamping press fixture
The 3927 N push at 0.5 MPa swages or clinches aluminium brackets on an appliance assembly line, with the 325 mm stroke clearing a deep die.
Pallet gate actuator
Swings a heavy safety gate on a warehouse conveyor, where the short ISO 21287 body fits between guard rails that a full-length profile cylinder cannot.
Monitored lift column
Raises a 200 kg fixture plate vertically with margin, while the fitted -S magnet and a DMSE switch confirm both end positions to the PLC.
Replacing the Airtac ACP Compact Cylinder ACP100X325SB with the ACE100X325SB
If 3927 N at 0.5 MPa is more than the job needs, the 80 mm bore gives 2513.3 N push and 2356.2 N pull in the same compact family; if you need more, the 100 mm bore is the largest in the range, with a theoretical 800.9 kgf at 1.0 MPa. The 325 mm stroke exceeds the 300 mm standard maximum for this bore, so it is built to order - confirm lead time. Choose the B male rod thread where the fixture bolts to the rod, or the female-thread version for rod knuckles. The fitted -S magnet pairs with CMSE / DMSE switches, and FA/FB flange, LB foot or CA/CB clevis mounts bolt to the ISO 21287 face. For new builds, order ACE100X325 instead.
Replacement checklist
- ✓ Current-production ACE → ACE100X325SB
- ✓ 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 ACP100X325SB 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. The theoretical maximum is 800.9 kgf at 1.0 MPa. For real work, plan on about 2356 N (roughly 60% of the push rating), which is about 240 kg of usable vertical lift at 0.5 MPa. Operating range is 0.15-1.0 MPa (22-145 psi) with 1.5 MPa (215 psi) proof pressure, and speed is 30-500 mm/s.
AirTAC no longer produces the ACP family. The current direct is ACE100X325, the ISO 21287 successor in the same bore, stroke and force class, with the same short body and mounting family. Because the ACP was built to the DIN standard, verify the ISO 21287 mounting dimensions against your fixture before swapping. The 325 mm stroke is non-standard for this bore (standard maximum is 300 mm), so confirm it is quoted as a made-to-order stroke on the ACE as well.
