This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACE12X10B, 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.

The AirTAC ACP Compact Cylinder ACP12X10B is a double acting DIN-standard tight/compact air cylinder with a Ø12mm bore and 10mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACE12X10B (ISO 21287 ACE), in the same bore, stroke and force class.
The ACP12X10B is a double acting DIN-standard compact cylinder with a 12 mm bore and a 10 mm stroke, delivering 56.5 N of push and 42.4 N of pull at 0.5 MPa (79.2 N / 59.4 N at 0.7 MPa). Air drives the rod in both directions, and a fixed TPU bumper sits at each end. The hard-anodized aluminium body with an S45C hard-chrome rod runs on 0.15-1.0 MPa (22-145 psi) at 30-500 mm/s. The B code gives a male rod thread; the port is M5x0.8.
Its short ISO 21287-class body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight fixtures and small assemblies. At 0.5 MPa the push force equals roughly 5.7 kg of thrust, so plan on about 3.4 kg of usable vertical load with a sensible margin. Note this model is discontinued: the current-production replacement is the ACE12X10, so confirm ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACE12X10B (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.
| 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 ACE12X10B produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.
| ACP | DIN compact cylinder (double-acting, discontinued). |
|---|---|
| 12 | Bore size in mm. |
| ×10 | Stroke length in mm. |
| S | Optional built-in magnet for sensor position sensing (omit for no magnet). |
| B | Rod type: B = male thread; blank = female thread. |
Replacement mapping (swap P for E): ACP→ACE, ASP→ASE, ATP→ATE, ACPD→ACED, ACPJ→ACEJ. ACP-family: ACP (double acting), ASP / ATP (single acting push / pull), ACPD (double rod), ACPJ (double rod, adjustable stroke).
A 10 mm stroke with 56.5 N push at 0.5 MPa is enough to knock small plastic or stamped parts off a nest on an assembly bench without disturbing the fixture.
The short body fits inside a jig where a full-length cylinder will not; the male rod thread takes a threaded clamp tip directly.
With the optional -S magnet ordered, CMSE or DMSE switches confirm rod position on a 10 mm verification move in a test fixture.
At 12 mm bore you are at the bottom of the range: 56.5 N push at 0.5 MPa. If the load needs more, step up to the 16 mm bore (100.5 N push at 0.5 MPa) or the 20 mm bore (157.1 N). If this is oversized, no smaller bore exists in the family, so check whether a shorter stroke or lower pressure would do. The male rod thread (B code) suits knuckle and threaded-link attachments. This unit has no magnet; order the -S code if you later need CMSE or DMSE switch sensing. Since the ACP is discontinued, specify the ACE12X10 as the direct successor and verify the ISO 21287 mounting footprint.
Replacement checklist
Push is 56.5 N and pull is 42.4 N at 0.5 MPa; at 0.7 MPa push rises to 79.2 N and pull to 59.4 N. Theoretical maximum is 11.5 kgf at 1.0 MPa. It is double acting, runs 0.15-1.0 MPa (22-145 psi) at 30-500 mm/s, uses an M5x0.8 port, and the 6 mm rod ends in a male thread (B code).
Order the ACE12X10, the current-production ISO 21287 successor: swap the P for an E and you get the same 12 mm bore, 10 mm stroke and force class in a matching short body. Confirm the ISO 21287 mounting dimensions against your fixture before the swap, since the ACP was built to the DIN standard.
