This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACED20X45S, 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 ACPD20X45S
The AirTAC ACPD Double Rod Compact Cylinder ACPD20X45S is a double acting, double rod DIN-standard tight/compact air cylinder with a Ø20mm bore and 45mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACED20X45S (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPD Double Rod Compact Cylinder ACPD20X45S
Double acting with a rod leaving both covers, the ACPD20X45S pushes and pulls with identical force because each stroke works on the rod-side area: 117.8 N at 0.5 MPa and 164.9 N at 0.7 MPa in either direction. The 20 mm bore takes a 10 mm through-rod, the M5x0.8 port feeds air filtered to 40 um, and the speed range is 30-500 mm/s. This model carries the optional -S magnet, so CMSE or DMSE reed and solid-state switches can be clipped on for end-of-stroke sensing.
The short ISO 21287-class body saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, which is why it suits tight jigs and guarded stations. A hard-anodized aluminium body carries the S45C hard-chrome rod, and a fixed TPU bumper sits at each end. Note this ACPD series is discontinued; the current-production direct is the ACED20X45, so confirm ISO 21287 mounting dimensions before you swap.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACED20X45S (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 (Ø20mm)
| Pressure | Force (both ways) |
|---|---|
| 0.5 MPa | 118 N |
| 0.7 MPa | 165 N |
| Max (@1.0 MPa) | 24 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 ACPD20X45S Is Used
Fixture clamping on a CNC lathe
The 117.8 N symmetric force clamps small turned parts in a machining fixture, and the short body fits inside the tooling plate where a full-length cylinder cannot.
Push-off station on a packaging line
A rear rod drives a product kicker while the front rod returns a flag, and CMSE switches on the -S magnet confirm each 45 mm stroke at up to 500 mm/s.
Replacing the Airtac ACPD Double Rod Compact Cylinder ACPD20X45S with the ACED20X45S
At 117.8 N per side at 0.5 MPa, the 20 mm bore covers light clamping and transfer tasks; step down to the 16 mm bore (75.4 N) for smaller fixtures or up to the 25 mm bore (206.2 N) when the load grows. The 45 mm stroke sits well inside the 100 mm standard limit for this bore. Because the piston drifts when air is lost, add a rod lock or pilot check if the load must stay put. The through-rod resists rotation and lets the rear rod carry a sensor flag, and the -S magnet on this unit pairs with CMSE / DMSE switches. For new builds, order the ACED20X45 instead - it is the current ISO 21287 successor in the same force class.
Replacement checklist
- ✓ Current-production ACE → ACED20X45S
- ✓ 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 ACPD20X45S FAQ
Because it is a double-rod cylinder, force is equal in both directions: 117.8 N at 0.5 MPa and 164.9 N at 0.7 MPa, with a maximum of 24.0 kgf at 1.0 MPa. Operating pressure is 0.15-1.0 MPa (22-145 psi) with a 1.5 MPa (215 psi) proof rating, and speed runs 30-500 mm/s.
The short ISO 21287-class aluminium body cuts about 50% of the mounting length of an ISO 15552 profile cylinder, and FA/FB flange or LB foot mounts bolt to the standard face. The S in the model code means the optional -S magnet is fitted, so CMSE or DMSE switches can be mounted; without the S code there is no magnet. This model is discontinued - the ACED20X45 is the current direct, so verify ISO 21287 dimensions before ordering.
