This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACED16X40, 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 ACPD16X40
The AirTAC ACPD Double Rod Compact Cylinder ACPD16X40 is a double acting, double rod DIN-standard tight/compact air cylinder with a Ø16mm bore and 40mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACED16X40 (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPD Double Rod Compact Cylinder ACPD16X40
A double acting compact cylinder with a rod leaving both covers, the ACPD16X40 pushes and pulls with identical force because each stroke works on the rod-side area: 75.4 N at 0.5 MPa and 105.6 N at 0.7 MPa in either direction. The 16 mm bore carries an 8 mm rod with a female M4x0.7 thread and an M5x0.8 air port. The through-rod resists rotation and light side load, and the rear rod makes a handy sensor flag or symmetric mount point.
The short ISO 21287-class body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight fixtures, guards and small gantries. A fixed TPU bumper sits at both ends, the hard-anodized aluminium body pairs with an S45C hard-chrome rod, and speed runs 30-500 mm/s at 0.15-1.0 MPa (22-145 psi). Note this model is discontinued; the current direct is the ACED16X40 - confirm the ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACED16X40 (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 ACPD16X40 Is Used
Small-parts ejection
The 75.4 N both-way thrust nudges finished pins or bushings off a CNC fixture, and the rear rod carries a flag for a CMSE switch when the -S magnet is ordered.
Lab slide actuation
A 40 mm stroke with equal force in each direction shuttles a microscope-stage tray or reagent carrier, with the through-rod keeping the carriage square.
Carton flap tuck
About 45 N of practical force folds light carton flaps on a bench-top packaging rig, and the short body fits where a full-length cylinder cannot.
Replacing the Airtac ACPD Double Rod Compact Cylinder ACPD16X40 with the ACED16X40
At 75.4 N per side, the 16 mm bore suits light clamping and part presentation; step down to the 12 mm bore (42.4 N) for smaller loads or up to the 20 mm bore (117.8 N) when more push is needed. Because it is a plain double-rod cylinder, the piston drifts when air is lost - add a rod lock or pilot check if the load must stay put. FA/FB flange and LB foot mountings bolt to the standard face, and ordering the -S code adds the optional magnet for CMSE / DMSE switches; without -S no magnet is fitted. This unit is discontinued, so specify the ACED16X40 as the current-production equivalent.
Replacement checklist
- ✓ Current-production ACE → ACED16X40
- ✓ 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 ACPD16X40 FAQ
It is a double-rod cylinder, so 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 maximum of 15.4 kgf at 1.0 MPa. Both strokes use the rod-side area, so push never exceeds pull. Air supply is 0.15-1.0 MPa (22-145 psi) and speed is 30-500 mm/s.
The ACPD16X40 is discontinued; the current direct is the ACED16X40, which matches the same bore, stroke and force class - confirm the ISO 21287 mounting dimensions before swapping since the ACP is DIN-standard. The magnet is the optional -S code (enabling CMSE / DMSE switches), the port is M5x0.8, the rod thread is female M4x0.7, and the fixed TPU bumpers at each end only decelerate the piston - they never hold a load.
