This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACED16X40SB, 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 ACPD16X40SB
The AirTAC ACPD Double Rod Compact Cylinder ACPD16X40SB 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 ACED16X40SB (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPD Double Rod Compact Cylinder ACPD16X40SB
Double acting with a rod leaving both covers, the ACPD16X40SB pushes with the same 75.4 N at 0.5 MPa in either direction, because both strokes work on the rod-side area of the 16 mm bore. At 0.7 MPa that rises to 105.6 N each way. The male-threaded 8 mm rod at each end resists rotation and side load and gives a symmetric mount, so the rear rod can carry a sensor flag or a second tooling plate.
The short ISO 21287-class body cuts about 50% of the mounting length of an ISO 15552 profile cylinder, which is why this size suits tight jigs and guarding. Note this model is discontinued: the current-production direct is ACED16X40, same bore, stroke and force class, so confirm the ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACED16X40SB (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 ACPD16X40SB Is Used
Small-part ejection from plastic injection molds
The 75.4 N per side at 0.5 MPa is enough to push finished caps or bushings off a mold nest, and the 40 mm stroke clears the part in one move.
Position-flag sensing on electronics assembly fixtures
With the -S magnet fitted, a CMSE or DMSE switch on the body reads piston position while the rear rod drives a flag plate on a PCB handling jig.
Light press-fit of connectors in cable harness benches
The male-threaded rod accepts an I or Y knuckle to seat M8-style connectors, and the through-rod keeps the plunger true under slight side load.
Replacing the Airtac ACPD Double Rod Compact Cylinder ACPD16X40SB with the ACED16X40SB
At 75.4 N per side at 0.5 MPa, this 16 mm bore covers light clamping and part transfer. If your load needs more, step up to ACPD20X40SB for 117.8 N both ways; if less force and a shorter body work, ACPD12X40SB gives 42.4 N. This unit carries the optional -S magnet, so CMSE or DMSE reed and solid-state switches can be mounted for end-position sensing. Remember the piston will drift if air is lost, so add a rod lock or pilot check for a held load. Order ACED16X40 as the current replacement and verify the ISO 21287 mounting footprint first.
Replacement checklist
- ✓ Current-production ACE → ACED16X40SB
- ✓ 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 ACPD16X40SB FAQ
Yes, identical both ways because a rod exits each cover and both strokes use the rod-side area: 75.4 N at 0.5 MPa and 105.6 N at 0.7 MPa, with a maximum of 15.4 kgf at 1.0 MPa. Operating pressure is 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), speed 30-500 mm/s, and the fixed TPU bumper at each end only decelerates the piston at the ends of travel.
Order ACED16X40, the current-production ISO 21287 successor made by swapping the P for an E. It matches the same 16 mm bore, 40 mm stroke and force class, and the short body still saves about 50% of the mounting length of an ISO 15552 profile cylinder. Because the ACP was built to a DIN standard, confirm the ISO 21287 mounting dimensions and the M5x0.8 port position against your fixture before the swap.
