This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACED16X50, 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 ACPD16X50
The AirTAC ACPD Double Rod Compact Cylinder ACPD16X50 is a double acting, double rod DIN-standard tight/compact air cylinder with a Ø16mm bore and 50mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACED16X50 (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPD Double Rod Compact Cylinder ACPD16X50
A double acting compact cylinder with a rod exiting both covers, the ACPD16X50 delivers 75.4 N in each direction at 0.5 MPa (105.6 N at 0.7 MPa), because both strokes work on the rod-side area. The 16 mm bore drives an 8 mm rod through a 50 mm stroke at 30-500 mm/s, with a fixed TPU bumper at each end. Its hard-anodized aluminium body keeps the mounting length about 50% shorter than an ISO 15552 profile cylinder, so it slots into tight fixtures and guarding.
The through-rod resists rotation and side load and gives a symmetric mount, and the rear rod can carry a sensor flag on machines that need position feedback. Note that this model is discontinued: the current-production direct is the ACED16X50 in the same bore, stroke and force class, so confirm ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACED16X50 (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 ACPD16X50 Is Used
Reciprocating transfer slide
The through-rod on the ACPD16X50 carries a workpiece carrier back and forth on a small electronics assembly conveyor, with 75.4 N available in both directions so the return stroke is never the weak one.
Dual-end sensor flag driver
On a bottle-rail gate, the rear rod of this 16 mm cylinder carries a flag past a switch while the front rod actuates the gate, giving position feedback from one compact 50 mm stroke body.
Symmetric press-lite station
A lab fixture uses the equal 75.4 N output each way to seat and then eject small connector housings, with the fixed TPU bumpers softening both ends of the 50 mm travel.
Replacing the Airtac ACPD Double Rod Compact Cylinder ACPD16X50 with the ACED16X50
At 75.4 N per side, this 16 mm bore suits light clamping and transfer tasks; step down to the 12 mm bore (42.4 N) for smaller loads or up to the 20 mm bore (117.8 N) when you need more force in the same short body. Like any plain double-rod cylinder it will drift if air is lost, so add a rod lock or pilot check for a held load. The rod end here is female M4x0.7 and the port is M5x0.8 PT; FA/FB flange or LB foot mounts bolt to the ISO 21287 face. Position sensing requires the optional -S magnet code with CMSE or DMSE switches - this unit has no magnet fitted. Order the ACED16X50 as the current replacement.
Replacement checklist
- ✓ Current-production ACE → ACED16X50
- ✓ 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 ACPD16X50 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 the 16 mm bore, with a peak of 15.4 kgf at 1.0 MPa. Operating range is 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), speed 30-500 mm/s, and the port is M5x0.8.
Only if the optional -S magnet is ordered; this ACPD16X50 code has no magnet, so no CMSE or DMSE switch can be fitted. The model itself is discontinued - the current-production direct is the ACED16X50 (swap the P for an E), which matches the same bore, stroke and force class. Confirm the ISO 21287 mounting dimensions before swapping, since the ACP is DIN-standard.
