This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACED12X35SB, 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 ACPD Double Rod Compact Cylinder ACPD12X35SB
The AirTAC ACPD Double Rod Compact Cylinder ACPD12X35SB is a double acting, double rod 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 ACED12X35SB (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPD Double Rod Compact Cylinder ACPD12X35SB
Double acting with a rod leaving both covers, the ACPD12X35SB pushes and pulls with identical output because each stroke works on the rod-side area: 42.4 N at 0.5 MPa and 59.4 N at 0.7 MPa in either direction. The 12 mm bore carries a 6 mm through-rod with a male thread on both ends (the B code), and the fixed TPU bumper pads at each cover simply decelerate the piston at end of travel. This model is discontinued; the current-production direct is the ISO 21287 ACED12X35, so confirm mounting dimensions before swapping.
The short ISO 21287-class body saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, which is why it suits cramped sensor stations and small test rigs. Because the S code is ordered, the magnet is fitted, so CMSE or DMSE reed and solid-state switches can be clamped straight onto the body for end-of-stroke detection. As a planning figure, treat about 25 N (roughly 2.5 kg of vertical lift with a margin) as the usable working force at 0.5 MPa rather than the full 42.4 N rating.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACED12X35SB (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 | Force (both ways) |
|---|---|
| 0.5 MPa | 42 N |
| 0.7 MPa | 59 N |
| Max (@1.0 MPa) | 9 kgf |
Double-rod: a rod exits both covers, so output force is equal in both directions (rod-side area used).

Where the Airtac ACPD Double Rod Compact Cylinder ACPD12X35SB Is Used
PCB push-off station
The 42.4 N through-rod ejects finished circuit boards from a magazine rack, while the fitted magnet and a DMSE switch confirm each stroke on the SMT line.
Lab sample indexer
A 35 mm advance slides microplate trays between two assay positions, with the back-end rod carrying a flag past a CMSE sensor for cycle counting.
Vial sorting gate
Equal 42.4 N force both ways flips a lightweight divert gate between two pharma packaging lanes at up to 500 mm/s without needing a return spring.
Replacing the Airtac ACPD Double Rod Compact Cylinder ACPD12X35SB with the ACED12X35SB
At 42.4 N per direction this 12 mm bore suits light clamping, sorting and indication tasks; step up to the 16 mm bore (75.4 N at 0.5 MPa) if the load grows, or down to nothing smaller since 12 mm is the smallest in the family. The 35 mm stroke sits inside the 50 mm maximum standard stroke for this bore, so no made-to-order build is needed. Remember the piston drifts if air is lost - add a rod lock or pilot check valve where a held position matters. The male threaded rod on both ends accepts I/Y knuckles, and the through-rod resists rotation and light side load. Order the ACED12X35 as the current replacement.
Replacement checklist
- ✓ Current-production ACE → ACED12X35SB
- ✓ Same bore / stroke / force class
- ✓ Confirm ISO 21287 mounting dimensions
- ✓ Port/thread type (PT / G)
- ✓ Add -S for magnet if you need sensors
Airtac ACPD Double Rod Compact Cylinder ACPD12X35SB FAQ
Because a rod exits both covers, force is equal both ways: 42.4 N at 0.5 MPa and 59.4 N at 0.7 MPa, with a maximum of 8.6 kgf at 1.0 MPa. Operating pressure is 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), speed range 30-500 mm/s, and the 12 mm bore uses an M5x0.8 port with a 6 mm male-threaded rod.
No - the ACPD family is discontinued. The current-production successor is the ACED12X35 (swap the P for an E), an ISO 21287 compact cylinder in the same bore, stroke and force class. Confirm the ISO 21287 mounting dimensions before the swap, since the ACP follows the older DIN-standard footprint.
