This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACE100X20, 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 ACP100X20
The AirTAC ACP Compact Cylinder ACP100X20 is a double acting DIN-standard tight/compact air cylinder with a Ø100mm bore and 20mm stroke, 1/4" air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACE100X20 (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACP Compact Cylinder ACP100X20
The ACP100X20 is a double acting compact cylinder with a 100 mm bore and a short 20 mm stroke, built on the DIN-standard tight body: hard-anodized aluminium covers threaded onto the body, an S45C hard-chrome piston rod of 25 mm, and a fixed TPU bumper at each end. At 0.5 MPa it pushes with 3927 N and pulls with 3681.6 N; at 0.7 MPa those figures rise to 5497.8 N and 5154.2 N, with a theoretical ceiling of 800.9 kgf at 1.0 MPa. Air supply is 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), and rod speed runs 30-500 mm/s.
Because the short ISO 21287-class body saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, this 100 mm bore fits heavy clamping stations and press heads where a full-length body will not. FA/FB flange, LB foot, CA/CB clevis, CR, SDB pivot and FTC brackets bolt straight to the standard face. Note: this model is discontinued - the current-production direct is ACE100X20, so confirm ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACE100X20 (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 ACE100X20 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 ACP100X20 Is Used
Heavy clamp fixtures on CNC machining centres
The 3927 N push at 0.5 MPa clamps steel billets or cast housings in dedicated fixtures, and the 20 mm stroke suits swing clamps and short-reach clamp arms where travel is minimal.
Baling and compacting stations
The 100 mm bore delivers 5497.8 N at 0.7 MPa for compacting scrap, offcuts or packaging waste in tight machine frames, where the short body saves about half the length of an ISO 15552 profile cylinder.
Replacing the Airtac ACP Compact Cylinder ACP100X20 with the ACE100X20
At 100 mm bore this is the top of the ACP range: 3927 N push at 0.5 MPa against 1558.6 N from a 63 mm bore and 981.7 N from a 50 mm bore. If your clamp force calculation lands well under 2500 N, a 63 mm bore will do the same job in a smaller envelope; if you need more than about 3900 N at 0.5 MPa, no larger ACP bore exists, so split the load across two cylinders. Remember that a plain ACP does not hold position when air is lost - the piston drifts - so add a rod lock or pilot check valve for a held load. The 20 mm stroke is well inside the 300 mm maximum standard stroke for this bore, and the female M16x1.5 rod thread takes standard I/Y knuckles. This unit has no magnet fitted; order the -S code if you want CMSE / DMSE switch positions. Since ACP is discontinued, spec ACE100X20 as the current replacement and verify the ISO 21287 mounting dimensions.
Replacement checklist
- ✓ Current-production ACE → ACE100X20
- ✓ 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 ACP100X20 FAQ
At 0.5 MPa the double-acting ACP100X20 pushes 3927 N and pulls 3681.6 N; at 0.7 MPa it pushes 5497.8 N and pulls 5154.2 N; theoretical maximum is 800.9 kgf at 1.0 MPa. Operating pressure 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 temperature -20 to +70 C. The bore is 100 mm, the rod 25 mm with a female M16x1.5 thread, and the port is 1/4" PT.
Yes, the ACP family is no longer in production. The current-production direct is ACE100X20 (swap the P for an E), which matches the same 100 mm bore, 20 mm stroke and force class on the ISO 21287 short body - confirm the mounting dimensions before swapping, since the ACP was built to the DIN standard. For switching, the magnet is not fitted on this code; the optional -S version carries the magnet for CMSE / DMSE reed or solid-state switches. Mounting choices include FA/FB flange, LB foot, CA/CB clevis, CR, SDB pivot and FTC brackets, and the fixed TPU bumpers at both ends simply decelerate the rod - they never hold a load when air is lost.
