This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACED20X35, 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 ACPD20X35
The AirTAC ACPD Double Rod Compact Cylinder ACPD20X35 is a double acting, double rod DIN-standard tight/compact air cylinder with a Ø20mm bore and 35mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACED20X35 (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPD Double Rod Compact Cylinder ACPD20X35
Double acting and double-rod, the ACPD20X35 pushes a piston rod out of BOTH covers, so the 20 mm bore delivers the same 117.8 N at 0.5 MPa (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 side load, gives a symmetric mounting face, and lets the rear rod carry a sensor flag or a second tooling point. A fixed TPU bumper sits at each end of the travel, and speeds run from 30-500 mm/s.
The short ISO 21287-class body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight fixtures, guards and pick stations. The hard-anodized aluminium body carries an S45C hard-chrome rod, and the optional -S magnet (ordered as ACPD20X35S) enables CMSE / DMSE switches; without the -S code there is no magnet. Note that this model is discontinued - the current-production direct is the ACED20X35, so confirm ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACED20X35 (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 ACPD20X35 Is Used
PCB fixture clamping
The 35 mm stroke and equal 117.8 N force in both directions let one ACPD20X35 clamp a circuit board carrier on the front rod while the rear rod ejects it, all inside a compact SMT jig.
Pick-and-place flagging
With the optional -S magnet and a CMSE switch, the through-rod carries a position flag at the back cover on a small electronics gantry, confirming part present before the vacuum cup releases.
Push-pull slide transfer
A 20 mm double-rod cylinder drives a light slide on a pharmaceutical vial tray, pushing trays onto a conveyor at 0.5 MPa and retracting with identical force thanks to the rod-side area on both strokes.
Replacing the Airtac ACPD Double Rod Compact Cylinder ACPD20X35 with the ACED20X35
At 117.8 N per side at 0.5 MPa, the 20 mm bore suits light clamping and transfer jobs; step down to the 16 mm bore (75.4 N) for smaller parts or up to the 25 mm bore (206.2 N) when you need more grip. Remember that a plain double-rod cylinder drifts when air is lost - for a held load, add a rod lock or pilot check valve. Mount with FA/FB flange or LB foot brackets, order the -S code if you want CMSE / DMSE switch capability, and specify the ACED20X35 as the current replacement for new builds.
Replacement checklist
- ✓ Current-production ACE → ACED20X35
- ✓ 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 ACPD20X35 FAQ
Yes - because a rod exits both covers, both strokes use the rod-side area. At 0.5 MPa you get 117.8 N each way, at 0.7 MPa you get 164.9 N each way, and the maximum at 1.0 MPa is 24.0 kgf. Operating pressure is 0.15-1.0 MPa (22-145 psi) with a 1.5 MPa (215 psi) proof pressure, and speed runs 30-500 mm/s.
The short ISO 21287-class body saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, with a 20 mm bore, 35 mm stroke, 10 mm rod, M6x1.0 female rod thread and M5x0.8 ports. This model is discontinued; the current-production replacement is the ACED20X35 in the same bore, stroke and force class - confirm the ISO 21287 mounting dimensions before you swap, and order the -S code if you need CMSE / DMSE switch compatibility.
