This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACE100X50S, 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 ACP100X50S
The AirTAC ACP Compact Cylinder ACP100X50S is a double acting DIN-standard tight/compact air cylinder with a Ø100mm bore and 50mm stroke, 1/4" air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACE100X50S (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACP Compact Cylinder ACP100X50S
A double acting pneumatic cylinder with a 100 mm bore and 50 mm stroke, the ACP100X50S delivers 3927 N push and 3681.6 N pull at 0.5 MPa, rising to 5497.8 N push at 0.7 MPa, with a theoretical peak of 800.9 kgf at 1.0 MPa. The short ISO 21287-class body saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, so this heavy force fits clamping stations and press fixtures where a full-length cylinder will not. Air is filtered to 40 um, pressure runs 0.15-1.0 MPa (22-145 psi), and rod speed spans 30-500 mm/s.
This unit carries the optional -S magnet, so CMSE or DMSE reed and solid-state switches can be bolted on for end-of-stroke signalling without external brackets. The S45C hard-chrome rod ends in a female M16x1.5 thread, the 1/4" port suits bores 80 and up, and fixed TPU bumpers sit at both ends. Note that ACP is discontinued: the current-production direct is ACE100X50, so confirm ISO 21287 mounting dimensions before swapping. With air lost the piston drifts, so use a rod lock or pilot check valve for held loads.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACE100X50S (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 ACE100X50S 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 ACP100X50S Is Used
Heavy press-fit clamping
The 3927 N push at 0.5 MPa seats bearings or bushings into aluminium housings on a short-stroke assembly press, and the compact body slots between the frame rails.
Weld fixture hold-down
Clamps steel brackets against a weld table with about 2360 N of usable force, while the -S magnet and a DMSE switch confirm full clamp before the robot strikes the arc.
Replacing the Airtac ACP Compact Cylinder ACP100X50S with the ACE100X50S
At 100 mm bore this is the top of the range: 3927 N push at 0.5 MPa against 2513 N for an 80 mm bore and 1558 N for a 63 mm bore, so step down a size if your clamp force budget allows a smaller envelope. The 50 mm stroke sits well inside the 300 mm maximum standard stroke for this bore. FA/FB flange, LB foot and CA/CB clevis mountings bolt to the standard face, and the fitted -S magnet pairs with CMSE / DMSE switches. ACP100X50S is discontinued; order ACE100X50 as the current replacement and verify the ISO 21287 mounting dimensions first.
Replacement checklist
- ✓ Current-production ACE → ACE100X50S
- ✓ 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 ACP100X50S FAQ
Push is 3927 N and pull 3681.6 N at 0.5 MPa; at 0.7 MPa push reaches 5497.8 N and pull 5154.2 N, with a theoretical maximum of 800.9 kgf at 1.0 MPa. It is double acting with a 100 mm bore, 50 mm stroke, 25 mm rod, female M16x1.5 rod thread, 1/4" port, 0.15-1.0 MPa (22-145 psi) operating pressure, 1.5 MPa (215 psi) proof pressure, -20 to +70 C temperature range and 30-500 mm/s speed. Fixed TPU bumpers sit at both ends.
AirTAC no longer produces the ACP family. The current-production replacement is ACE100X50, the ISO 21287 successor in the same bore, stroke and force class. Because the ACP was built to a DIN-standard compact format, confirm the ISO 21287 mounting dimensions against your fixture before swapping, then order the ACE with the same mounting code and the -S magnet if you need CMSE / DMSE switch feedback.
