This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACED16X125B, 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 ACPD16X125B
The AirTAC ACPD Double Rod Compact Cylinder ACPD16X125B is a double acting, double rod DIN-standard tight/compact air cylinder with a Ø16mm bore and 125mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACED16X125B (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPD Double Rod Compact Cylinder ACPD16X125B
A double acting compact cylinder with a rod leaving both covers, the ACPD16X125B pushes and pulls with identical output: 75.4 N at 0.5 MPa and 105.6 N at 0.7 MPa in either direction, because both strokes work on the rod-side area of the 16 mm bore. The through-rod resists rotation and light side load, gives a symmetric mount, and the rear rod can carry a sensor flag, while fixed TPU bumpers decelerate the piston at each end. Note the 125 mm stroke is beyond the 75 mm standard limit for this bore, so it is a made-to-order build.
The hard-anodized aluminium body with an S45C hard-chrome rod follows the short ISO 21287-class format, saving roughly 50% of the mounting length of an ISO 15552 profile cylinder, which is why it suits tight jigs and guards. Run it on 0.15-1.0 MPa (22-145 psi) at 30-500 mm/s. This model is discontinued; the current direct is the ACED16X125, so confirm ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACED16X125B (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 ACPD16X125B Is Used
Lab slide transfer
The symmetric through-rod carries a small sample tray between two stations, with 75.4 N available in either direction so the return stroke is never the weak one.
Flag-driven position check
Mount a flag on the rear rod to trip a proximity sensor on a packaging fixture, confirming the 125 mm made-to-order stroke has fully extended.
Compact jig clamping
With about 4.6 kg of practical working force at 0.5 MPa, the short body clamps light aluminium parts inside a machining jig where a full-length cylinder will not fit.
Replacing the Airtac ACPD Double Rod Compact Cylinder ACPD16X125B with the ACED16X125B
Size both ways: if 75.4 N at 0.5 MPa is more than the job needs, the bore 12 version delivers 42.4 N; if it falls short, bore 20 gives 117.8 N in the same compact family. Remember that a plain double-rod cylinder drifts when air is lost, so add a rod lock or pilot check for a held load. There is no magnet on this code; order the -S variant if you want CMSE / DMSE switches, and pick FA/FB flange or LB foot mounting to match the fixture. Since ACPD is discontinued, spec the ACED16X125 as the current-production replacement and verify the ISO 21287 footprint.
Replacement checklist
- ✓ Current-production ACE → ACED16X125B
- ✓ 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 ACPD16X125B FAQ
Yes, both directions are equal because a rod exits each cover and both strokes use the rod-side area: 75.4 N at 0.5 MPa, 105.6 N at 0.7 MPa, with a maximum of 15.4 kgf at 1.0 MPa. Operating range is 0.15-1.0 MPa (22-145 psi), speed 30-500 mm/s, and the 125 mm stroke is a non-standard, made-to-order length for this bore.
The hard-anodized aluminium body follows the short ISO 21287-class format, cutting roughly 50% of the mounting length compared with an ISO 15552 profile cylinder, and FA/FB flange or LB foot mounts bolt to a standard face. The ACPD16X125B itself is discontinued; the current direct is the ACED16X125 with the same bore, stroke and force class, so confirm the ISO 21287 mounting dimensions before ordering.
