This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACED16X20S, 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 ACPD16X20S
The AirTAC ACPD Double Rod Compact Cylinder ACPD16X20S is a double acting, double rod DIN-standard tight/compact air cylinder with a Ø16mm 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 ACED16X20S (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPD Double Rod Compact Cylinder ACPD16X20S
A double acting, double-rod compact cylinder, the ACPD16X20S pushes a 16 mm bore through a 20 mm stroke with a rod leaving both covers, so the force is identical in each direction: 75.4 N at 0.5 MPa and 105.6 N at 0.7 MPa on the rod-side area. The through-rod resists rotation and light side load, gives a symmetric mounting point, and lets the rear rod carry a sensor flag, while fixed TPU bumpers decelerate the piston at both ends. Running on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi), it strokes at 30-500 mm/s.
The short ISO 21287-class body saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight pick-and-place heads and small fixtures. The -S code on this model means the optional magnet is fitted, so CMSE or DMSE reed and solid-state switches can be clipped on for end-of-stroke detection. Note that this model is discontinued: the current-production direct is ACED16X20, so confirm the ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACED16X20S (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 (Ø16mm)
| Pressure | Force (both ways) |
|---|---|
| 0.5 MPa | 75 N |
| 0.7 MPa | 106 N |
| Max (@1.0 MPa) | 15 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 ACPD16X20S Is Used
Small-part ejection from plastic molds
The symmetric 75.4 N push and pull clears finished caps or connectors off a benchtop mold in both stroke directions within a 20 mm throw.
Position-flagged test fixtures
With the fitted -S magnet driving CMSE or DMSE switches, the rear rod flag confirms end positions on a 16 mm bore electronics test jig.
Light hold-down on conveyor gating
About 45 N of practical working force at 0.5 MPa secures small cartons or trays under a guide on a bottling-line transfer conveyor.
Replacing the Airtac ACPD Double Rod Compact Cylinder ACPD16X20S with the ACED16X20S
At 75.4 N per side, the 16 mm bore suits light clamping and small part transfer; drop to the 12 mm bore (42.4 N at 0.5 MPa) for gentler handling, or step up to 20 mm (117.8 N) when a fixture needs more grip. The 20 mm stroke sits well inside the 75 mm standard limit for this bore. The female M4x0.7 rod thread on both ends accepts standard rod knuckles, and FA/FB flange or LB foot mounts bolt to the compact face. Because the piston drifts when air is lost, add a rod lock or pilot check if a load must be held. Order ACED16X20 as the current replacement.
Replacement checklist
- ✓ Current-production ACE → ACED16X20S
- ✓ 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 ACPD16X20S FAQ
Because a rod exits both covers, output is equal both ways: 75.4 N at 0.5 MPa and 105.6 N at 0.7 MPa, taken on the rod-side area. At a full 1.0 MPa the bore reaches about 15.4 kgf. The piston runs at 30-500 mm/s between fixed TPU bumpers, and the 20 mm stroke is within the 75 mm standard range for the 16 mm bore.
No - the ACPD family is discontinued. The current-production direct is ACED16X20, which swaps the P for an E and matches the same bore, stroke and force class in the ISO 21287 short-body format. Confirm the ISO 21287 mounting dimensions against your fixture before ordering, since the ACP was built to the older DIN-standard pattern.
