This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACED20X5SB, 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 ACPD20X5SB
The AirTAC ACPD Double Rod Compact Cylinder ACPD20X5SB is a double acting, double rod DIN-standard tight/compact air cylinder with a Ø20mm bore and 5mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACED20X5SB (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPD Double Rod Compact Cylinder ACPD20X5SB
A double acting compact cylinder with a rod exiting both covers, the ACPD20X5SB delivers an identical 117.8 N in each direction at 0.5 MPa (164.9 N at 0.7 MPa) because both strokes work on the rod-side area of the 20 mm bore. The 5 mm stroke suits tiny positioning moves, and the male rod thread (B code) bolts straight to tooling. Its hard-anodized aluminium body keeps the mounting length about 50% shorter than an ISO 15552 profile cylinder, so it slots into cramped fixtures and small gantries.
Because the through-rod is guided at both covers, it resists rotation and light side load and gives a symmetric mount for clamping plates or a sensor flag on the rear rod. A fixed TPU bumper sits at each end, and speed runs 30-500 mm/s over 0.15-1.0 MPa (22-145 psi). Note this model is discontinued: the current-production direct is the ISO 21287 ACED20X5, so confirm mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACED20X5SB (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 ACPD20X5SB Is Used
Micro press for connector pins
The 117.8 N per direction at 0.5 MPa seats small pins in PCB connectors, and the 5 mm stroke keeps the cycle fast and repeatable.
Sensor-flag carrier on a test rig
The rear rod drives a flag past a CMSE or DMSE switch, giving a positive end-of-stroke signal on an automated leak-test station.
Symmetric push-pull in a jig
Equal force both ways lets one cylinder eject then retract a locator pin in a machining jig without changing pressure.
Replacing the Airtac ACPD Double Rod Compact Cylinder ACPD20X5SB with the ACED20X5SB
At 117.8 N per side, bore 20 covers small clamps and part-presenting moves; step down to bore 16 (75.4 N at 0.5 MPa) for lighter loads or up to bore 25 (206.2 N) when you need more grip. The 5 mm stroke is well inside the 100 mm standard range for this bore. This unit already carries the optional -S magnet, so CMSE / DMSE switches can be added for end-position sensing, and FA/FB flange or LB foot mounts bolt to the same face. Like any plain double-rod cylinder it will drift if air is lost, so add a rod lock or pilot check where a load must be held. Order the ACED20X5 as the current replacement.
Replacement checklist
- ✓ Current-production ACE → ACED20X5SB
- ✓ 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 ACPD20X5SB FAQ
Both directions give the same force because a rod exits each cover: 117.8 N at 0.5 MPa and 164.9 N at 0.7 MPa, equal to about 24.0 kgf at the 1.0 MPa maximum. Operating range is 0.15-1.0 MPa (22-145 psi) with a 1.5 MPa (215 psi) proof pressure.
The hard-anodized aluminium body follows the short DIN-standard format, saving roughly 50% of the mounting length of an ISO 15552 profile cylinder, with a fixed TPU bumper at each end. The ACPD family is discontinued; the current direct is the ISO 21287 ACED20X5, so verify mounting dimensions before ordering.
