This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACE100X20SB, 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 ACP100X20SB
The AirTAC ACP Compact Cylinder ACP100X20SB 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 ACE100X20SB (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACP Compact Cylinder ACP100X20SB
The ACP100X20SB is a double acting DIN-standard compact cylinder with a 100 mm bore and a short 20 mm stroke, delivering 3927 N of push force and 3681.6 N of pull force at 0.5 MPa (rising to 5497.8 N at 0.7 MPa). Its short ISO 21287-class body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into press fixtures and gantries where a full-length body will not fit. The S code means the optional -S magnet is fitted, so CMSE or DMSE reed and solid-state switches can be mounted directly on the hard-anodized aluminium body.
At the rod end this model carries a male thread (the B code) with a 25 mm rod, and air ports are 1/4". Note that this ACP model is discontinued: the current-production direct is ACE100X20, which matches the same bore, stroke and force class, so confirm the ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACE100X20SB (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 ACE100X20SB 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 ACP100X20SB Is Used
Short-stroke press fixture
The 3927 N push at 0.5 MPa (5497.8 N at 0.7 MPa) suits a 20 mm staking or marking press on an aluminum bracket line, where the compact body fits inside the press frame.
Clamp on a machining center fixture
With the male rod thread and a 25 mm rod, the cylinder clamps a cast-iron housing in a CNC fixture; the fitted -S magnet drives a CMSE switch to confirm clamp closure before cycle start.
Pallet stopper on a heavy conveyor
The short body bolts into the conveyor side rail and extends 20 mm to stop pallets weighing up to about 200 kg, matching the vertical-lift equivalent of the 3927 N thrust.
Replacing the Airtac ACP Compact Cylinder ACP100X20SB with the ACE100X20SB
If 3927 N of push at 0.5 MPa is more than the job needs, the ACP80X20SB offers 2513.3 N at the same pressure in a smaller 80 mm bore; if the load is heavier, step up is not available beyond 100 mm in this family, so consider parallel cylinders or a larger ACE bore. The 20 mm stroke is well inside the 300 mm maximum standard stroke for bore 100, so it is a standard catalog build. Remember that a plain cylinder drifts when air is lost - for a held load add a rod lock or pilot check valve. This model is discontinued; order ACE100X20 and verify the ISO 21287 mounting footprint first.
Replacement checklist
- ✓ Current-production ACE → ACE100X20SB
- ✓ 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 ACP100X20SB 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 is 5154.2 N; theoretical maximum is 800.9 kgf at 1.0 MPa. It is a double acting compact cylinder, 100 mm bore, 20 mm stroke, 25 mm rod with male thread, 1/4" ports, operating pressure 0.15-1.0 MPa (22-145 psi), proof 1.5 MPa (215 psi), speed 30-500 mm/s, temperature -20 to +70 C, with a fixed TPU bumper at both ends.
Order ACE100X20: swap the P for an E and you get the current-production ISO 21287 compact cylinder in the same bore, stroke and force class. Because the ACP was built to a DIN standard, confirm the ISO 21287 mounting dimensions and the FA/FB flange, LB foot or CA/CB clevis interface before swapping. This model also carries the optional -S magnet, so if you use CMSE or DMSE switches, check the ACE ordering code keeps the S.
