This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACE12X35SB, 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 ACP12X35SB
The AirTAC ACP Compact Cylinder ACP12X35SB 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 ACE12X35SB (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACP Compact Cylinder ACP12X35SB
The ACP12X35SB is a double acting DIN-standard compact cylinder with a 12 mm bore and 35 mm stroke, delivering 56.5 N push and 42.4 N pull at 0.5 MPa (79.2 N / 59.4 N at 0.7 MPa, 11.5 kgf theoretical maximum at 1.0 MPa). Air extends and retracts the rod, fixed TPU bumpers decelerate at both ends, and the male rod thread (B code) suits knuckle and tooling attachments. This model carries the optional -S magnet, so CMSE / DMSE reed or solid-state switches can be mounted for end-of-stroke sensing.
Its hard-anodized aluminium body is an ISO 21287 short build that saves about 50% of the mounting length of an ISO 15552 profile cylinder, which is why it fits tight jigs, small guards and bench fixtures. Note: this model is discontinued - the current-production direct is the ACE12X35, so confirm ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACE12X35SB (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 ACE12X35SB 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 ACP12X35SB Is Used
Micro part ejection from a jig
A 12 mm bore pushing 56.5 N at 0.5 MPa is sized for nudging small machined or moulded parts off a locating pin on a bench fixture, with the 35 mm stroke clearing the part without overtravel.
Position-verified slide gate on a small assembly cell
Because this model carries the -S magnet, CMSE or DMSE switches confirm gate open and closed positions on a compact guarding slide where a full-length cylinder would not fit.
Replacing the Airtac ACP Compact Cylinder ACP12X35SB with the ACE12X35SB
At 12 mm bore this is the smallest force class in the range: 56.5 N push at 0.5 MPa. If your load needs more, step up to the 16 mm bore (100.5 N push at 0.5 MPa); for lighter pick-and-place work the same 12 mm bore at a shorter or longer stroke is usually enough. The 35 mm stroke sits well inside the 50 mm maximum standard stroke for this bore, so no made-to-order stroke is needed. The male rod thread (B) pairs with I/Y knuckles; FA/FB flange, LB foot and CA/CB clevis mountings bolt to the ISO 21287 face. Because a plain cylinder drifts when air is lost, add a rod lock or pilot check valve if the load must stay put. Order the ACE12X35 as the current replacement for this discontinued model.
Replacement checklist
- ✓ Current-production ACE → ACE12X35SB
- ✓ 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 ACP12X35SB FAQ
At 0.5 MPa it pushes 56.5 N and pulls 42.4 N; at 0.7 MPa that rises to 79.2 N push and 59.4 N pull. The theoretical maximum is 11.5 kgf at 1.0 MPa. Operating pressure is 0.15-1.0 MPa (22-145 psi) with a 1.5 MPa (215 psi) proof pressure, and speed runs 30-500 mm/s.
The hard-anodized aluminium body is an ISO 21287 short build, saving about 50% of the mounting length of an ISO 15552 profile cylinder, with a 6 mm rod, M5x0.8 ports, a male rod thread and fixed TPU bumpers at both ends. The -S magnet this model carries allows CMSE / DMSE switches for end-of-stroke signalling. The ACP12X35SB is discontinued; the ACE12X35 is the current direct - confirm ISO 21287 mounting dimensions before swapping.
