This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACED16X40B, 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 ACPD16X40B
The AirTAC ACPD Double Rod Compact Cylinder ACPD16X40B 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 ACED16X40B (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPD Double Rod Compact Cylinder ACPD16X40B
A double acting compact cylinder with a rod leaving both covers, the ACPD16X40B 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 16 mm bore carries a 40 mm stroke on an 8 mm rod with a male thread (the B code), fed through M5x08 ports - written M5x0.8 - and runs at 30-500 mm/s on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi).
The short ISO 21287-class body saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight fixtures, and the through-rod resists rotation and side load while the rear rod can carry a sensor flag. Fixed TPU bumpers sit at both ends. Note: this model is discontinued; the current-production direct is ACED16X40 - confirm ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACED16X40B (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 ACPD16X40B Is Used
Small-part ejection from a jig
The 75.4 N both-ways output clears finished bushings or pins out of a drilling fixture, with the 40 mm stroke matching shallow pockets on a compact bench jig.
Push-pull slide on a lab automation deck
Equal force in both directions makes the through-rod ideal for a reciprocating carrier that must return a vial tray with the same 75.4 N it pushed out with.
Flag-driven position check on a packaging head
With the optional -S magnet ordered, a CMSE or DMSE switch reads the rear rod flag to confirm the sealing pad reached the 40 mm end of travel.
Replacing the Airtac ACPD Double Rod Compact Cylinder ACPD16X40B with the ACED16X40B
At 75.4 N per side, this 16 mm bore suits light clamping and transfer; 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 margin. The 40 mm stroke sits well inside the 75 mm standard limit for this bore. The male rod thread (B) takes I/Y knuckles directly; FA/FB flange and LB foot mounts bolt to the same face. If you need position feedback, order the -S code - without it no magnet is fitted and no CMSE / DMSE switch can be read. A plain double-rod cylinder drifts when air is lost, so add a rod lock or pilot check for held loads. For new builds, specify ACED16X40 instead.
Replacement checklist
- ✓ Current-production ACE → ACED16X40B
- ✓ 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 ACPD16X40B FAQ
Yes - the double-rod design gives equal force both ways: 75.4 N at 0.5 MPa and 105.6 N at 0.7 MPa per direction, with a maximum of 15.4 kgf at 1.0 MPa. Both strokes use the rod-side area, so there is no push/pull difference. It runs on 0.15-1.0 MPa (22-145 psi) air at 30-500 mm/s.
The short ISO 21287-class aluminium body cuts about 50% of the mounting length of an ISO 15552 profile cylinder, with fixed TPU bumpers at both ends and FA/FB flange or LB foot mounting. The ACPD16X40B is discontinued; order ACED16X40 as the current direct and confirm the ISO 21287 mounting dimensions before the swap.
