This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACED20X150S, 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.

The AirTAC ACPD Double Rod Compact Cylinder ACPD20X150S 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 ACED20X150S (ISO 21287 ACE), in the same bore, stroke and force class.
The ACPD20X150S is a double acting, double-rod compact cylinder built to the DIN-standard ACP pattern: a 20 mm bore with a 10 mm rod exiting BOTH covers, so the through-rod delivers an equal 117.8 N in each direction at 0.5 MPa (164.9 N at 0.7 MPa). Its 150 mm stroke is longer than the 100 mm standard limit for this bore, so it is a made-to-order stroke. The hard-anodized aluminium body with an S45C hard-chrome rod runs on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi), 30-500 mm/s, with a fixed TPU bumper at each end.
Because the short ISO 21287-class body saves about 50% of the mounting length of an ISO 15552 profile cylinder, it slots into narrow slides and pick stations where a full-length body will not reach. The through-rod resists rotation and side load and lets the rear rod carry a sensor flag. Note this model is discontinued; the current-production direct is the ACED20X150.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACED20X150S (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.
| 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).
| ACPD | DIN compact cylinder (double-rod, discontinued). |
|---|---|
| 20 | Bore size in mm. |
| ×150 | Stroke length in mm. |
| S | Optional built-in magnet for sensor position sensing (omit for no magnet). |
| B | Rod type: B = male thread; blank = female thread. |
Replacement mapping (swap P for E): ACP→ACE, ASP→ASE, ATP→ATE, ACPD→ACED, ACPJ→ACEJ. ACP-family: ACP (double acting), ASP / ATP (single acting push / pull), ACPD (double rod), ACPJ (double rod, adjustable stroke).
The through-rod pushes and pulls with the same 117.8 N at 0.5 MPa, ideal for a lab fixture that must stroke a 150 mm path in both directions at identical force.
With the -S magnet already fitted, a CMSE switch on the body trips a vision check each time the 10 mm rod reaches end of stroke on a small-parts sorting line.
A rear rod on a small gantry counter-guide carries the same load as the working rod, keeping a 6 kg carrier level through the 150 mm travel.
Size both ways: if 117.8 N at 0.5 MPa is more than your fixture needs, the 16 mm bore ACPD16 gives 75.4 N; if you need more, the 25 mm bore ACPD25 delivers 206.2 N. All three share the M5x0.8 port. This model already carries the optional -S magnet, so CMSE / DMSE reed or solid-state switches can be mounted directly for end-of-stroke detection. A plain double-rod cylinder will not hold position when air is lost - the piston drifts - so add a rod lock or pilot check for a held load. Order the ACED20X150 as the current replacement and confirm the ISO 21287 mounting dimensions before swapping.
Replacement checklist
Because a rod exits both covers, force is equal both ways: 117.8 N at 0.5 MPa and 164.9 N at 0.7 MPa, on the rod-side area. At 1.0 MPa the peak is 24 kgf. Operating range is 0.15-1.0 MPa (22-145 psi), proof 1.5 MPa (215 psi), speed 30-500 mm/s, port M5x0.8, female rod thread M6x1.0.
Strokes beyond 100 mm on the 20 mm bore are made to order, so this unit is built as a non-standard stroke. The ACPD family is discontinued; the current-production successor is the ACED20X150 (swap the P for an E), which matches the same bore, stroke and force class - confirm the ISO 21287 mounting dimensions before swapping, since the ACP is DIN-standard.
