This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACE100X70S, 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 ACP100X70S
The AirTAC ACP Compact Cylinder ACP100X70S is a double acting DIN-standard tight/compact air cylinder with a Ø100mm bore and 70mm stroke, 1/4" air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACE100X70S (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACP Compact Cylinder ACP100X70S
Double acting and built to the DIN-standard compact format, the ACP100X70S moves its 25 mm rod with air on both strokes and carries a fixed TPU bumper at each end. At 0.5 MPa it pushes 3927 N and pulls 3681.6 N, rising to 5497.8 N on the extend stroke at 0.7 MPa - a theoretical 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 it slots into presses and gantries where a full-length body simply will not fit. The S in the 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.
Plan on about 2356 N of real work at 0.5 MPa rather than the full 3927 N rating - roughly a 240 kg vertical lift once you keep a sensible margin. The hard-anodized aluminium body with threaded aluminium covers and an S45C hard-chrome rod runs on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi), 30-500 mm/s, -20 to +70 C. Note that this model is discontinued: the current-production direct is the ACE100X70, which matches 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 ACE100X70S (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 ACE100X70S 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 ACP100X70S Is Used
Baling and compacting stations
The 3927 N extend force at 0.5 MPa suits a recycling baler platen with a short 70 mm compression stroke inside a tight frame.
Clamping heavy weld fixtures
About 240 kg of vertical-equivalent holding lets a fixture clamp swing arms or axle housings firmly between robotic weld cycles.
Pallet gate and stopper actuation
The short body plus 1/4" ports drive conveyor gate drop mechanisms in warehouse lines where a full-length profile cylinder cannot fit.
Replacing the Airtac ACP Compact Cylinder ACP100X70S with the ACE100X70S
At 100 mm bore this is the top of the ACP range: 3927 N push at 0.5 MPa where an 80 mm bore gives 2513.3 N and there is no larger standard option. If your load needs under about 2356 N of usable force, the 80 mm size saves air and cost; for the full 3927 N class with position feedback, stay with this -S version and pair it with CMSE or DMSE switches. Remember the rod drifts when air is lost - add a rod lock or pilot check valve if the load must stay put. Mount with FA/FB flange, LB foot or CA/CB clevis brackets on the standard face, order the PT port thread or G, and specify the ACE100X70 as the current replacement for new builds.
Replacement checklist
- ✓ Current-production ACE → ACE100X70S
- ✓ 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 ACP100X70S 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. 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. A usable working figure is about 2356 N, roughly a 240 kg vertical lift with margin.
Order the ACE100X70, the current-production ISO 21287 successor made by swapping the P for an E. It matches the same 100 mm bore, 70 mm stroke and force class with a matching short body and mounting family, but confirm the ISO 21287 mounting dimensions before swapping since the ACP was built to a DIN standard. This unit is double acting with a fixed TPU bumper at both ends, and the -S magnet it carries accepts CMSE or DMSE switches.
