This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACE100X70B, 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 ACP100X70B
The AirTAC ACP Compact Cylinder ACP100X70B 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 ACE100X70B (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACP Compact Cylinder ACP100X70B
The ACP100X70B is a double acting compact cylinder with a 100 mm bore and 70 mm stroke, built to the DIN-standard short-body format with a hard-anodized aluminium body and an S45C hard-chrome piston rod. 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 peak of 800.9 kgf at 1.0 MPa. The B code gives a male rod thread on the 25 mm rod, and air is supplied through a 1/4" port. Operating range is 0.15-1.0 MPa (22-145 psi) with speeds of 30-500 mm/s.
This model is discontinued; the current-production direct is the ACE100X70 (swap the P for an E), which matches the same bore, stroke and force class in the ISO 21287 family - confirm the mounting dimensions before swapping, since the ACP follows the DIN format. The short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it suits tight press fixtures and gantries. Fixed TPU bumpers at both ends soften end-of-travel only; they never hold a load, so add a rod lock or pilot check valve if the position must survive a loss of air.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACE100X70B (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 ACE100X70B 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 ACP100X70B Is Used
Baling press platen
With 3927 N at 0.5 MPa and a 70 mm stroke, the 100 mm bore drives a recycling baler platen for short compaction moves where a full-length cylinder will not fit.
Pallet clamp actuation
The short body and about 200 kg vertical-lift capability suit clamp arms on palletizers that grip and release loads within a 70 mm stroke window.
Stamping die ejection
A 25 mm male-thread rod delivers 5497.8 N at 0.7 MPa to eject formed sheet-metal parts from stamping dies in tight die-set pockets.
Replacing the Airtac ACP Compact Cylinder ACP100X70B with the ACE100X70B
At 100 mm bore this is the top of the ACP range: 3927 N push at 0.5 MPa versus 2513.3 N for the 80 mm bore, so step down only if your load is under about 150 kg lifted. If 3927 N is marginal, note the theoretical 800.9 kgf at 1.0 MPa leaves headroom at higher supply pressure. The 70 mm stroke sits well inside the 300 mm maximum standard stroke for this bore. The B code specifies a male rod thread; omit it for a female M16x1.5 rod end. Mounting brackets (FA/FB flange, LB foot, CA/CB clevis) bolt to the standard face, and if you need position sensing, order the -S variant to enable CMSE / DMSE switches - this code has no magnet fitted. For new builds, specify the ACE100X70 instead, as ACP is discontinued.
Replacement checklist
- ✓ Current-production ACE → ACE100X70B
- ✓ 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 ACP100X70B FAQ
At 0.5 MPa it pushes with 3927 N and pulls with 3681.6 N. At 0.7 MPa the push is 5497.8 N and the pull 5154.2 N. The theoretical maximum at 1.0 MPa is 800.9 kgf. It is double acting, runs at 30-500 mm/s on air filtered to 40 um, and operates from 0.15-1.0 MPa (22-145 psi) with a 1.5 MPa (215 psi) proof pressure. Note the model is discontinued; the ACE100X70 is the current equivalent.
Only if the magnet is ordered. This ACP100X70B code has no magnet, so no switch can be detected. Order the -S variant to get the optional magnet, then CMSE or DMSE reed or solid-state switches can be clipped to the body. Also remember the fixed TPU bumpers only decelerate at end of stroke - they do not lock the load, so use a rod lock or pilot check valve where holding is required.
