This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACED12X40SB, 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 ACPD12X40SB
The AirTAC ACPD Double Rod Compact Cylinder ACPD12X40SB is a double acting, double rod DIN-standard tight/compact air cylinder with a Ø12mm bore and 40mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACED12X40SB (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPD Double Rod Compact Cylinder ACPD12X40SB
Double acting and double rod, the ACPD12X40SB pushes a 12 mm bore through a 40 mm stroke with a piston rod leaving both covers, so the force is identical in each direction: 42.4 N at 0.5 MPa and 59.4 N at 0.7 MPa, both ways. The male rod thread (B code) takes a standard nut, the -S magnet is fitted so CMSE or DMSE switches can be clipped on, and a fixed TPU bumper sits at each end. Air supply is 0.15-1.0 MPa (22-145 psi) with speed from 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 pick heads and tight fixture pockets. Because the through-rod resists rotation and light side load, the rear rod can carry a sensor flag or a second tool. Note that this model is discontinued; the current direct is ACED12X40, so confirm ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACED12X40SB (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 ACPD12X40SB Is Used
Small-part ejection from plastic molds
The symmetric 42.4 N push and pull at 0.5 MPa clears tiny molded clips from a cavity in both directions, and the 40 mm stroke fits inside a narrow mold base.
Position-flagged check fixture
With the -S magnet fitted, a CMSE switch confirms the 40 mm stroke on an automotive bracket gauge, while the rear rod drives a matching indicator flag.
Lab sample press
About 25 N of usable force at 0.5 MPa seats microscope slide covers or vial caps gently, with the through-rod keeping the plunger from rotating.
Replacing the Airtac ACPD Double Rod Compact Cylinder ACPD12X40SB with the ACED12X40SB
At 42.4 N per side at 0.5 MPa, this 12 mm bore handles small clamping and part-presenting duties; step up to bore 16 (75.4 N) for slightly heavier caps or down to a single-rod ACP when a rear rod is not needed. The 40 mm stroke sits inside the 50 mm maximum standard stroke for this bore, so no made-to-order build is required. The fitted -S magnet pairs with CMSE / DMSE switches, and FA/FB flange or LB foot mounts bolt to the ISO 21287 face. A plain double-rod cylinder will drift if air is lost, so add a rod lock or pilot check for a held load. Order ACED12X40 as the current replacement and verify mounting dimensions.
Replacement checklist
- ✓ Current-production ACE → ACED12X40SB
- ✓ 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 ACPD12X40SB 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, using the rod-side area on each stroke. At 1.0 MPa the peak is 8.6 kgf. Operating range is 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), speed 30-500 mm/s, temperature -20 to +70 C, with air filtered to 40 um.
The ISO 21287-class short body cuts roughly 50% of the mounting length compared with an ISO 15552 profile cylinder, so it slots into slim gripper assemblies and fixture pockets. This model carries the optional -S magnet for CMSE / DMSE switches, a male rod thread, an M5x08 port written M5x0.8, and fixed TPU bumpers at both ends. It is discontinued; the current direct is ACED12X40 - confirm ISO 21287 mounting dimensions before converting.
