This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACED16X125SB, 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 ACPD16X125SB
The AirTAC ACPD Double Rod Compact Cylinder ACPD16X125SB 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 ACED16X125SB (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPD Double Rod Compact Cylinder ACPD16X125SB
Double acting with a rod leaving both covers, the ACPD16X125SB 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. The through-rod resists rotation and light side load, gives a symmetric mount, and the rear rod can carry a sensor flag. A fixed TPU bumper sits at each end, and speed runs 30-500 mm/s at 0.15-1.0 MPa (22-145 psi).
The hard-anodized aluminium body follows the ISO 21287 short format, cutting roughly 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight fixtures. This unit carries the optional -S magnet, so CMSE or DMSE switches can be fitted for position feedback. Note the 125 mm stroke exceeds the 75 mm standard maximum for a 16 mm bore, so it is made to order. The ACPD family is discontinued; the current direct is ACED16X125, same bore, stroke and force class - confirm ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACED16X125SB (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 ACPD16X125SB Is Used
Position-flagged slide check
The rear rod carries a flag past a CMSE switch (enabled by the fitted -S magnet), confirming a 125 mm transfer slide has fully retracted in a small assembly cell.
Symmetric light clamping
Equal 75.4 N force both ways clamps and releases small electronics housings with the same pressure, no direction-dependent tuning needed.
Compact gantry pusher
The short ISO 21287 body fits inside a narrow jig frame where a full-length profile cylinder cannot, ejecting finished parts at up to 500 mm/s.
Replacing the Airtac ACPD Double Rod Compact Cylinder ACPD16X125SB with the ACED16X125SB
At 75.4 N per side, this 16 mm bore suits light clamping and transfer; step down to a 12 mm bore (42.4 N) for smaller parts or up to 20 mm (117.8 N) when more force is needed. The male rod thread (B code) takes standard rod accessories directly. Remember the piston drifts when air is lost - add a rod lock or pilot check if the load must stay put. For new designs, order the ACED16X125 instead, as ACPD is out of production.
Replacement checklist
- ✓ Current-production ACE → ACED16X125SB
- ✓ 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 ACPD16X125SB 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 on every stroke, with a peak of 15.4 kgf at 1.0 MPa. Operating range is 0.15-1.0 MPa (22-145 psi), proof 1.5 MPa (215 psi), speed 30-500 mm/s, port M5x0.8, male rod thread. As a rule of thumb, plan on about 45 N (roughly 4.5 kg vertical equivalent) of real work at 0.5 MPa rather than the full rating.
The standard maximum stroke for a 16 mm ACPD bore is 75 mm, so 125 mm is a made-to-order build with longer lead time. The ACPD family is discontinued; the current-production replacement is ACED16X125, which swaps the P for an E and matches the same bore, stroke and force class. Confirm the ISO 21287 mounting dimensions before swapping, since the ACP was built to a DIN-standard footprint.
