This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACED20X20S, 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 ACPD20X20S
The AirTAC ACPD Double Rod Compact Cylinder ACPD20X20S is a double acting, double rod DIN-standard tight/compact air cylinder with a Ø20mm bore and 20mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACED20X20S (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPD Double Rod Compact Cylinder ACPD20X20S
Double acting with a rod leaving both covers, the ACPD20X20S pushes and pulls with identical force because each stroke works on the rod-side area: 117.8 N at 0.5 MPa and 164.9 N at 0.7 MPa in either direction. The 20 mm bore drives a 10 mm rod through a 20 mm stroke at 30-500 mm/s, with a fixed TPU bumper at each end. Its short ISO 21287-class body saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight jigs and guarding. This model carries the optional -S magnet, so CMSE or DMSE reed and solid-state switches can be clamped on for end-of-stroke sensing.
Note that the piston drifts if air is lost, so a held load needs a rod lock or pilot check valve. The ACPD family is discontinued; the current-production direct is the ACED20X20, and you should confirm the ISO 21287 mounting dimensions before swapping since the ACP is DIN-standard.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACED20X20S (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 ACPD20X20S Is Used
Bidirectional pusher on a small assembly bench
The equal 117.8 N force in both directions lets one cylinder eject a finished connector housing and retract the empty pallet without any valve-side force derating.
Position-flagged slide in a test fixture
With the -S magnet fitted, a DMSE switch on either end confirms clamp and release on a 20 mm stroke, while the rear rod carries a second flag for a redundant check.
Replacing the Airtac ACPD Double Rod Compact Cylinder ACPD20X20S with the ACED20X20S
At 117.8 N per side at 0.5 MPa, the 20 mm bore sits between the 16 mm (75.4 N) and 25 mm (206.2 N) double-rod versions - step down for light gates, up if your tooling mass grows. The through-rod resists rotation and light side load and gives a symmetric mount, and the rear rod can carry a sensor flag. Mounting covers FA/FB flange and LB foot, with CA/CB clevis, CR, SDB pivot and FTC brackets plus I/Y knuckles available in the family. The female M6x1.0 rod thread and 1/8-class M5x0.8 ports suit small manifolds. Remember this model is discontinued - order the ACED20X20 as the current equivalent and verify ISO 21287 hole patterns first.
Replacement checklist
- ✓ Current-production ACE → ACED20X20S
- ✓ 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 ACPD20X20S FAQ
Yes - as a double-rod cylinder both strokes use the rod-side area, so force is equal in extend and retract: 117.8 N at 0.5 MPa, 164.9 N at 0.7 MPa, and a maximum of 24.0 kgf at 1.0 MPa. Operating range is 0.15-1.0 MPa (22-145 psi) with 1.5 MPa (215 psi) proof pressure, running on air filtered to 40 um at 30-500 mm/s and -20 to +70 C.
The ACPD20X20S is no longer in production; the current direct is the ACED20X20 in the same bore, stroke and force class. Confirm the ISO 21287 mounting dimensions before swapping, since the ACP is DIN-standard. This unit carries the optional -S magnet, so CMSE or DMSE reed or solid-state switches can be mounted for end-of-stroke detection.
