This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACED20X80SB, 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 ACPD20X80SB
The AirTAC ACPD Double Rod Compact Cylinder ACPD20X80SB is a double acting, double rod DIN-standard tight/compact air cylinder with a Ø20mm bore and 80mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACED20X80SB (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPD Double Rod Compact Cylinder ACPD20X80SB
Double acting with a rod leaving both covers, the ACPD20X80SB pushes and pulls with identical force: 117.8 N at 0.5 MPa and 164.9 N at 0.7 MPa in each direction, because both strokes work on the rod-side area. The through-rod resists rotation and light side load, gives a symmetric mount, and the rear rod can carry a sensor flag. A fixed TPU bumper sits at each end and stroke speed runs 30-500 mm/s.
The 20 mm bore body is a short ISO 21287-class compact build in hard-anodized aluminium with an S45C hard-chrome rod, saving roughly 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight jigs and guarding. This unit carries the optional -S magnet, so CMSE / DMSE reed or solid-state switches can be clipped on for end-of-stroke sensing. Note it is discontinued: the current-production direct is the ACED20X80, same bore, stroke and force class.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACED20X80SB (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 ACPD20X80SB Is Used
Reciprocating parts transfer
The through-rod drives a small slide on a PCB or connector assembly line, pushing and pulling with the same 117.8 N at 0.5 MPa so the return stroke needs no derating.
Position-flagged test fixtures
With the -S magnet fitted, CMSE or DMSE switches confirm end positions on a gauge or leak-test stand, while the rear rod carries a mechanical flag for visual checks.
Light press and ejection duty
Ejects stamped terminals or molded inserts from a die on a 30-500 mm/s cycle, with the fixed TPU bumpers absorbing the end-of-stroke shock.
Replacing the Airtac ACPD Double Rod Compact Cylinder ACPD20X80SB with the ACED20X80SB
At 117.8 N per side at 0.5 MPa, bore 20 suits light clamping and transfer tasks; step down to bore 16 (75.4 N) for smaller loads or up to bore 25 (206.2 N) when you need roughly 75% more force. The 80 mm stroke sits inside the 100 mm standard limit for this bore, so no made-to-order build is needed. Male rod thread (B code) with PT ports; FA/FB flange or LB foot mounts bolt to the ISO 21287 face. A plain double-rod cylinder drifts when air is lost, so add a rod lock or pilot check if the load must stay put. Order the ACED20X80 as the current replacement and confirm ISO 21287 mounting dimensions before swapping.
Replacement checklist
- ✓ Current-production ACE → ACED20X80SB
- ✓ 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 ACPD20X80SB FAQ
Because it is a double-rod cylinder, force is equal in both directions: 117.8 N at 0.5 MPa and 164.9 N at 0.7 MPa per side (rod-side area both ways). Maximum output at 1.0 MPa is 24.0 kgf. Operating pressure is 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi).
No - the ACPD family is discontinued. The current-production direct is the ACED20X80 (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 swapping, since the ACP was built to a DIN-standard footprint.
