This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACED20X65SB, 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 ACPD20X65SB
The AirTAC ACPD Double Rod Compact Cylinder ACPD20X65SB 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 ACED20X65SB (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPD Double Rod Compact Cylinder ACPD20X65SB
A double acting, double-rod compact cylinder in the DIN-standard ACP family, the ACPD20X65SB runs a 20 mm bore with a 65 mm stroke and a 10 mm piston rod that exits BOTH covers. Because both strokes work on the rod-side area, output is identical each way: 117.8 N at 0.5 MPa and 164.9 N at 0.7 MPa. The male rod thread (B code) bolts straight to tooling, and the through-rod resists rotation and light side load while the rear rod can carry a sensor flag. The 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 to the body for end-of-stroke sensing. A fixed TPU bumper sits at each end, and speed spans 30-500 mm/s on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi). Note that the ACPD family is discontinued: the current-production direct is the ACED20X65, and buyers should confirm the ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACED20X65SB (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 ACPD20X65SB Is Used
Push-pull fixture clamping
The equal 117.8 N thrust in both directions lets one cylinder clamp a workpiece on the forward stroke and release the nest on the return, with the male rod thread driving the clamp arm directly.
Bidirectional part diverter
A rod on each cover means the same 164.9 N at 0.7 MPa can kick cartons or trays left or right on a packaging line without flipping the cylinder around.
Position-flagged indexing slide
With the -S magnet fitted, CMSE / DMSE switches read end-of-stroke off the body while the rear rod drives an indicator flag on a small assembly indexing table.
Replacing the Airtac ACPD Double Rod Compact Cylinder ACPD20X65SB with the ACED20X65SB
At 117.8 N per direction, 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 more thrust is needed. The 65 mm stroke sits inside the 100 mm maximum standard stroke for this bore, so no made-to-order length is required. Like any plain double-rod cylinder it will drift when air is lost - add a rod lock or pilot check valve if the load must stay put. The male rod thread pairs with I/Y knuckles on the ISO 21287 mounting face, and the -S magnet in this model accepts CMSE / DMSE switches. For new projects, order the ACED20X65 instead.
Replacement checklist
- ✓ Current-production ACE → ACED20X65SB
- ✓ 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 ACPD20X65SB 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, with a maximum of 24.0 kgf at 1.0 MPa. Operating pressure is 0.15-1.0 MPa (22-145 psi) with a 1.5 MPa (215 psi) proof rating, and speed runs 30-500 mm/s. In practice, budget about 70 N (roughly 7 kg) of usable vertical work at 0.5 MPa instead of the full rating.
The hard-anodized aluminium body follows the short ISO 21287-class format, cutting about 50% of the mounting length of an ISO 15552 profile cylinder, with FA/FB flange, LB foot and clevis-style brackets available. A fixed TPU bumper decelerates the piston at each end. The ACPD family is discontinued - the current-production replacement is the ACED20X65 in the same bore, stroke and force class, so confirm the ISO 21287 mounting dimensions before ordering.
