This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACED12X45SB, 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 ACPD12X45SB
The AirTAC ACPD Double Rod Compact Cylinder ACPD12X45SB is a double acting, double rod DIN-standard tight/compact air cylinder with a Ø12mm bore and 45mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACED12X45SB (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPD Double Rod Compact Cylinder ACPD12X45SB
A double acting compact cylinder with a rod leaving both covers, the ACPD12X45SB pushes and pulls with identical force because both strokes work on the rod-side area: 42.4 N at 0.5 MPa and 59.4 N at 0.7 MPa in each direction. The 12 mm bore drives a 6 mm through-rod over a 45 mm stroke, with a male rod thread (B code) at each end and an M5x0.8 air port. The S in the code means the optional -S magnet is fitted, so CMSE or DMSE reed and solid-state switches can be clipped on for end-of-stroke sensing.
The short ISO 21287-class body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into slim fixtures where a full-length body cannot. A fixed TPU bumper pads each end of travel, the hard-anodized aluminium body carries an S45C hard-chrome rod, and speed runs 30-500 mm/s at 0.15-1.0 MPa (22-145 psi). Note this model is discontinued: the current-production direct is ACED12X45, so confirm ISO 21287 mounting dimensions before swapping. As a rule of thumb, plan on roughly 25 N (about 2.5 kg of vertical lift) of real work at 0.5 MPa rather than the full 42.4 N rating.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACED12X45SB (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 ACPD12X45SB Is Used
Presence check on electronics assembly lines
The fitted -S magnet drives a CMSE or DMSE switch at each end, so a PCB pusher can confirm board placement at 30-500 mm/s without an external sensor bracket.
Symmetric push-off in small jig fixtures
Equal 42.4 N output both ways lets one cylinder eject a machined bushing from a drill jig and retract with the same force, keeping cycle forces balanced.
Reciprocating shuttle in lab dispensing rigs
The rear rod carries a flag past a DMSE switch while the front rod shuttles a microdispenser head, all inside a body about 50% shorter than an ISO 15552 profile cylinder.
Replacing the Airtac ACPD Double Rod Compact Cylinder ACPD12X45SB with the ACED12X45SB
At 42.4 N per side, this 12 mm bore suits light clamping and sensing tasks; step down is not possible in this family, while a 16 mm bore gives 75.4 N at 0.5 MPa if you need more margin. The through-rod resists rotation and side load, and the rear rod can carry a sensor flag. Remember the piston drifts if air is lost - for a held load add a rod lock or pilot check valve. Mounting brackets from the FA/FB flange and LB foot family bolt to the ISO 21287 face. Since ACPD is discontinued, order ACED12X45 as the current equivalent and verify the mounting dimensions.
Replacement checklist
- ✓ Current-production ACE → ACED12X45SB
- ✓ 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 ACPD12X45SB FAQ
Yes - the double-rod design works on the rod-side area both ways, so output is identical pushing and pulling: 42.4 N at 0.5 MPa, 59.4 N at 0.7 MPa, and up to 8.6 kgf at 1.0 MPa. Operating range is 0.15-1.0 MPa (22-145 psi) with 1.5 MPa (215 psi) proof pressure, speed 30-500 mm/s, and the bore-12 port is M5x0.8. Plan on about 25 N (roughly 2.5 kg vertical lift) as usable working force at 0.5 MPa.
No - the ACPD family is discontinued. The current-production direct is ACED12X45 (swap the P for an E), an ISO 21287 compact cylinder in the same bore, stroke and force class with FA/FB flange and LB foot mounting options. Because the ACP was DIN-standard, confirm the ISO 21287 mounting dimensions before swapping. The replacement keeps the fixed TPU bumper at both ends and accepts the optional -S magnet for CMSE / DMSE switches.
