This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACE12X35B, 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 ACP12X35B
The AirTAC ACP Compact Cylinder ACP12X35B is a double acting DIN-standard tight/compact air cylinder with a Ø12mm bore and 35mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACE12X35B (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACP Compact Cylinder ACP12X35B
A double acting compact cylinder in the DIN-standard ACP series, the ACP12X35B pairs a 12 mm bore with a 35 mm stroke and a male rod thread (the B code). At 0.5 MPa it pushes 56.5 N and pulls 42.4 N, rising to 79.2 N push at 0.7 MPa, with a theoretical ceiling of 11.5 kgf at 1.0 MPa. Its hard-anodized aluminium body and S45C hard-chrome rod run on 0.15-1.0 MPa (22-145 psi) of filtered air at 30-500 mm/s.
The short ISO 21287-class body saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, which is why this size suits slim fixtures and guarded assemblies. Note this model is discontinued: the current direct is the ACE12X35, so confirm ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACE12X35B (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 (Ø12mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 57 N | 42 N |
| 0.7 MPa | 79 N | 59 N |
| Max (@1.0 MPa) | 12 kgf | |
The ACE12X35B 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 ACP12X35B Is Used
Micro part ejection
Ejects small machined pins or stamped parts from a die or nest; the 56.5 N push at 0.5 MPa is ample for gram-range components, and the short body slots beside the tool.
Slide gate actuation
Opens and closes a small divertor gate on a lab or packaging line; with the -S magnet ordered, CMSE or DMSE switches confirm gate position at each end.
Test rig push-off
Pushes samples off a fixture in an electronics test bench; the 35 mm stroke and 30-500 mm/s speed range match quick, short indexing moves.
Replacing the Airtac ACP Compact Cylinder ACP12X35B with the ACE12X35B
At 12 mm bore this is the smallest ACP size; step up to the 16 mm bore (100.5 N push at 0.5 MPa) if your clamp needs more force, or down is not possible - 12 mm is the floor of the range. The 35 mm stroke sits inside the 50 mm standard limit for this bore, so no made-to-order stroke is needed. The B code gives a male rod thread; order without B for a female rod end. This unit has no magnet - add the -S code if you want CMSE or DMSE switch sensing. For new builds, specify the ACE12X35 instead, as ACP is discontinued.
Replacement checklist
- ✓ Current-production ACE → ACE12X35B
- ✓ 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 ACP12X35B FAQ
Push is 56.5 N and pull 42.4 N at 0.5 MPa; at 0.7 MPa push rises to 79.2 N and pull to 59.4 N, with a theoretical maximum of 11.5 kgf at 1.0 MPa. It is double acting, 12 mm bore, 35 mm stroke, 6 mm rod, M5x0.8 port, male rod thread (B code), operating on 0.15-1.0 MPa (22-145 psi) at 30-500 mm/s with fixed TPU bumpers at both ends.
Order the ACE12X35, the ISO 21287 successor: swap the P for an E and you get the same bore, stroke and force class in a matching short body. Before swapping, confirm the ISO 21287 mounting dimensions, since the ACP was built to a DIN-standard footprint. Also remember the magnet is only fitted when the -S code is ordered.
