This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACE100X40SB, 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 ACP100X40SB
The AirTAC ACP Compact Cylinder ACP100X40SB is a double acting DIN-standard tight/compact air cylinder with a Ø100mm bore and 40mm stroke, 1/4" air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACE100X40SB (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACP Compact Cylinder ACP100X40SB
Double acting and built to the DIN-standard compact format, the ACP100X40SB squeezes a 100 mm bore and 40 mm stroke into a short hard-anodized aluminium body that saves about 50% of the mounting length of an ISO 15552 profile cylinder. At 0.5 MPa it pushes 3927 N and pulls 3681.6 N; at 0.7 MPa push rises to 5497.8 N. The 25 mm S45C hard-chrome rod carries a male thread (the B code), ports are 1/4" PT, and a fixed TPU bumper sits at both ends.
This model carries the optional -S magnet, so CMSE or DMSE reed and solid-state switches can be clamped straight onto the body for end-of-stroke sensing. Note that ACP is discontinued: the current-production direct is the ISO 21287 ACE100X40, so confirm the mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACE100X40SB (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 ACE100X40SB 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 ACP100X40SB Is Used
Heavy clamp fixture on a machining line
With 3927 N push at 0.5 MPa, the 100 mm bore clamps large castings in a milling fixture, and the short body fits where a full-length profile cylinder cannot.
Press-fit station for bearing assembly
Around 240 kg of usable thrust at 0.5 MPa presses bearings into housings on a 40 mm stroke, with CMSE switches confirming bottom position via the -S magnet.
Gate and guard actuation on material handling equipment
The male-threaded 25 mm rod drives heavy sliding gates and safety guards, with the fixed TPU bumper softening each end of travel at up to 500 mm/s.
Replacing the Airtac ACP Compact Cylinder ACP100X40SB with the ACE100X40SB
At this bore size the ACP100X40SB sits near the top of the range: step down to an 80 mm bore for 2513 N push at 0.5 MPa, or stay at 100 mm when you need the full 3927 N. The 40 mm stroke is well inside the 300 mm maximum standard stroke for bore 100, so no made-to-order stroke is involved. Remember the piston drifts when air is lost - for a held load add a rod lock or pilot check valve. FA/FB flange, LB foot and CA/CB clevis mountings bolt to the same face, and the ACE100X40 is the current replacement.
Replacement checklist
- ✓ Current-production ACE → ACE100X40SB
- ✓ 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 ACP100X40SB 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. The theoretical maximum is 800.9 kgf at 1.0 MPa. Operating pressure is 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), speed 30-500 mm/s, and the 1/4" PT port suits this 100 mm bore. The model is discontinued; ACE100X40 is the direct successor.
It is a compact double-acting cylinder with a hard-anodized aluminium body, aluminium covers and a 25 mm hard-chrome rod with a male thread. A fixed TPU bumper at each end decelerates travel but never holds a load. This version carries the optional -S magnet, so CMSE or DMSE switches can be fitted for position feedback. For replacement, order ACE100X40 and verify the ISO 21287 mounting dimensions.
