This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACED20X75SB, 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 ACPD20X75SB
The AirTAC ACPD Double Rod Compact Cylinder ACPD20X75SB is a double acting, double rod DIN-standard tight/compact air cylinder with a Ø20mm bore and 75mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACED20X75SB (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPD Double Rod Compact Cylinder ACPD20X75SB
Double acting with a rod leaving both covers, the ACPD20X75SB is a DIN-standard compact cylinder whose 20 mm bore delivers 117.8 N at 0.5 MPa in each direction, because both strokes work on the rod-side area. The 75 mm stroke sits inside the 100 mm standard limit for this bore, and the male rod thread (B code) bolts straight to I/Y knuckles. At 0.7 MPa the same piston gives 164.9 N either way, so a symmetric fixture can push and pull with identical force.
The through-rod resists rotation and light side load, and the rear rod can carry a sensor flag for a second switch position. This unit carries the optional -S magnet, so CMSE or DMSE reed and solid-state switches mount directly on the hard-anodized aluminium body. Note that ACPD is discontinued: the current-production direct is the ISO 21287 ACED20X75, so confirm mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACED20X75SB (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 (Ø20mm)
| Pressure | Force (both ways) |
|---|---|
| 0.5 MPa | 118 N |
| 0.7 MPa | 165 N |
| Max (@1.0 MPa) | 24 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 ACPD20X75SB Is Used
Pick-and-place flip station
The through-rod drives a 180-degree flipper on a small-parts assembly cell, giving 117.8 N of equal clamping force on both the push and pull stroke at 0.5 MPa.
Gantry z-axis with two switch points
With the -S magnet fitted, CMSE switches on both rods signal top-of-stroke and mid-position on a 75 mm vertical lift of about 6 kg fixture weight.
Compact ejection unit in a jig
The short ISO 21287-class body, roughly 50% shorter in mounting length than an ISO 15552 profile cylinder, ejects stamped terminals inside a tight press fixture.
Replacing the Airtac ACPD Double Rod Compact Cylinder ACPD20X75SB with the ACED20X75SB
Size between bores: an ACPD16X75 gives 75.4 N at 0.5 MPa, while stepping up to ACPD25X75 reaches 206.2 N, so choose 20 mm when the 117.8 N class matches the part weight. The 75 mm stroke is standard (max 100 mm for this bore), so no made-to-order build is needed. Pick LB foot or FA/FB flange mounts on the ISO 21287 face, and order CMSE or DMSE switches only because this S-coded unit carries the -S magnet. A plain double-rod cylinder drifts when air is lost, so add a rod lock or pilot check for a held load. Replacement: ACED20X75, same bore, stroke and force class.
Replacement checklist
- ✓ Current-production ACE → ACED20X75SB
- ✓ 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 ACPD20X75SB FAQ
Because a rod exits both covers, force is equal both ways: 117.8 N at 0.5 MPa and 164.9 N at 0.7 MPa, with a maximum of 24.0 kgf at 1.0 MPa. Operating pressure is 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), speed 30-500 mm/s, and the port is M5x0.8. The male rod thread is sized for this bore per the datasheet.
No, the ACPD family is discontinued. The current-production replacement is the ISO 21287 ACED20X75, a direct in the same bore, stroke and force class with a matching short body and mounting family. Confirm the ISO 21287 mounting dimensions against your fixture before swapping, since the ACP is DIN-standard. This unit carries the optional -S magnet for CMSE / DMSE switches, and a fixed TPU bumper decelerates at each end.
