This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACED20X65S, 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 ACPD20X65S
The AirTAC ACPD Double Rod Compact Cylinder ACPD20X65S is a double acting, double rod DIN-standard tight/compact air cylinder with a Ø20mm bore and 65mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACED20X65S (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPD Double Rod Compact Cylinder ACPD20X65S
A double acting compact cylinder with a rod leaving both covers, the ACPD20X65S 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 takes a 10 mm through-rod, and the S code means the magnet for CMSE / DMSE switches is already fitted. Note this model is discontinued; the current-production successor is ACED20X65.
The short ISO 21287-class body saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight fixtures and guarding. A fixed TPU bumper sits at each end, the hard-anodized aluminium body carries an S45C hard-chrome rod, and speed runs 30-500 mm/s.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACED20X65S (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 ACPD20X65S Is Used
Two-sided fixture clamping
The through-rod lets a small electronics jig clamp a PCB carrier from both covers with the same 117.8 N at 0.5 MPa, using one cylinder instead of two opposed units.
Symmetric part transfer
On a bottling line guide rail, the 65 mm stroke pushes empty containers off a conveyor in either direction with equal 164.9 N at 0.7 MPa, no matter which side is pressurized.
Position-flagged slide actuation
With the fitted -S magnet and CMSE / DMSE switches on both ends, a lab automation slide confirms extend and retract positions while the rear rod drives a mirror flag.
Replacing the Airtac ACPD Double Rod Compact Cylinder ACPD20X65S with the ACED20X65S
At 117.8 N per side at 0.5 MPa this 20 mm bore suits light clamping and transfer tasks; step down to the 16 mm bore (75.4 N) for smaller loads or up to the 25 mm bore (206.2 N) when more force is needed. The 65 mm stroke sits inside the 100 mm maximum standard stroke for this bore. The through-rod resists rotation and side load and gives a symmetric mount, and the rear rod can carry a sensor flag. FA/FB flange or LB foot mounting bolts to the ISO 21287 face. A plain double-rod cylinder will not hold position if air is lost, so add a rod lock or pilot check for a held load. For new projects, order ACED20X65 and confirm the ISO 21287 mounting dimensions before swapping.
Replacement checklist
- ✓ Current-production ACE → ACED20X65S
- ✓ 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 ACPD20X65S FAQ
Because a rod exits both covers, output is equal both ways: 117.8 N at 0.5 MPa and 164.9 N at 0.7 MPa on each stroke, 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. This model is discontinued; ACED20X65 is the current replacement in the same force class.
It is a compact short-body cylinder whose aluminium body saves about 50% of the mounting length of an ISO 15552 profile cylinder, with a fixed TPU bumper at each end and a female M6x1.0 rod thread. The S code means the optional -S magnet is fitted, so CMSE / DMSE reed or solid-state switches can be mounted directly on the body. Before ordering, verify the ISO 21287 mounting dimensions against your fixture.
