This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACED20X150SB, 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 ACPD20X150SB
The AirTAC ACPD Double Rod Compact Cylinder ACPD20X150SB is a double acting, double rod DIN-standard tight/compact air cylinder with a Ø20mm bore and 150mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACED20X150SB (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPD Double Rod Compact Cylinder ACPD20X150SB
A double acting, double-rod compact cylinder built to the DIN-standard ACP pattern, the ACPD20X150SB pushes a 20 mm piston through a 150 mm stroke with a rod leaving both covers. Because both strokes work on the rod-side area, output is identical in each direction: 117.8 N at 0.5 MPa and 164.9 N at 0.7 MPa. The 150 mm stroke is longer than the 100 mm standard for this bore, so it is made to order. Note this model is discontinued - the current-production direct is the ISO 21287 ACED20X150, so confirm mounting dimensions before swapping.
The through-rod resists rotation and side load and gives a symmetric mount, and the rear rod can carry a sensor flag or a second tooling plate. The short ISO 21287-class body saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, which suits tight gantries and slide units. The S code fits the magnet, so CMSE or DMSE switches mount directly; a fixed TPU bumper sits at each end and speed runs 30-500 mm/s.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACED20X150SB (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 ACPD20X150SB Is Used
Reciprocating slide units
The equal 117.8 N output in both directions drives a light pick-and-place slide back and forth at the same speed and force, with the rear rod carrying a position flag for the CMSE switch.
Fixture clamping on small CNC parts
About 70 N of practical work force at 0.5 MPa clamps aluminium brackets or plastic housings in a drilling fixture, and the through-rod keeps the clamp plate square under side load.
Replacing the Airtac ACPD Double Rod Compact Cylinder ACPD20X150SB with the ACED20X150SB
Size up or down by force: the 16 mm bore gives 75.4 N at 0.5 MPa while the 25 mm bore reaches 206.2 N, so this 20 mm unit at 117.8 N sits between them for light clamping and lift tasks. If the load must stay put when air is lost, add a rod lock or pilot check - a plain through-rod cylinder drifts. FA/FB flange and LB foot mountings bolt to the standard face, and the fitted -S magnet accepts CMSE / DMSE switches. Order the ACED20X150 as the current replacement and verify ISO 21287 dimensions.
Replacement checklist
- ✓ Current-production ACE → ACED20X150SB
- ✓ 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 ACPD20X150SB FAQ
Yes - the double-rod design works on the rod-side area for both strokes, so output is equal each way: 117.8 N at 0.5 MPa and 164.9 N at 0.7 MPa, peaking at 24.0 kgf at 1.0 MPa. Operating pressure is 0.15-1.0 MPa (22-145 psi) with 1.5 MPa (215 psi) proof pressure, and speed runs 30-500 mm/s.
The standard stroke limit for this bore is 100 mm, so 150 mm is a made-to-order non-standard stroke. The ACPD family is discontinued; the current-production replacement is the ACED20X150 in the ISO 21287 series, which matches the bore, stroke and force class. Confirm the ISO 21287 mounting dimensions before swapping, since the ACP follows the DIN-standard pattern.
