This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACED20X10S, 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 ACPD20X10S is a double acting, double rod DIN-standard tight/compact air cylinder with a Ø20mm bore and 10mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACED20X10S (ISO 21287 ACE), in the same bore, stroke and force class.
Double acting with a rod leaving both covers, the ACPD20X10S pushes and pulls with identical output: 117.8 N at 0.5 MPa and 164.9 N at 0.7 MPa in either direction, because both strokes work on the rod-side area of the 20 mm bore. The through-rod resists rotation and light side load, gives a symmetric mounting plane, and the rear rod can carry a sensor flag. This unit carries the optional -S magnet, so CMSE or DMSE reed and solid-state switches can be clipped on for end-of-stroke signalling.
The short ISO 21287-class body saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, which is why 10 mm-stroke versions like this suit tight slides, clamps and test fixtures. A fixed TPU bumper sits at each end, the hard-anodized aluminium body carries an S45C hard-chrome rod, and speed runs 30-500 mm/s at 0.15-1.0 MPa (22-145 psi). Note the ACPD family is discontinued; the current direct is ACED20X10, so confirm ISO 21287 mounting dimensions before swapping. As a sizing rule, plan on about 70 N (roughly 7 kg) of real work at 0.5 MPa rather than the full 117.8 N rating.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACED20X10S (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. |
| ×10 | 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 10 mm stroke and 117.8 N per side at 0.5 MPa suit pressing dowel pins or bushings into plastic housings on an electronics assembly bench, with equal force on the return stroke clearing the part.
With the -S magnet fitted, CMSE or DMSE switches confirm both end positions on a short indexing slide, and the rear rod doubles as a flag carrier for a second sensing point.
A compact 20 mm clamp that fits inside a benchtop test rig guard, holding PCBs or small castings at about 7 kg of usable vertical force while the through-rod keeps the clamp nose from rotating.
At 117.8 N per direction at 0.5 MPa, the 20 mm bore suits light clamping and part-presenting; drop to the 16 mm bore (75.4 N) for gentler loads or step up to 25 mm (206.2 N) if you need more margin. If the load must stay put when air is lost, add a rod lock or pilot check - a plain through-rod cylinder drifts. This -S version already includes the magnet for CMSE / DMSE switches, and FA/FB flange or LB foot mounts bolt to the standard face. Since ACPD is discontinued, order ACED20X10 as the current-production equivalent and verify the ISO 21287 footprint.
Replacement checklist
Yes - the double-rod design means both strokes use the rod-side area, so force is equal both ways: 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 range is 0.15-1.0 MPa (22-145 psi), speed 30-500 mm/s, and the bore 20 port is M5x0.8 with an M6x1.0 female rod thread.
Order ACED20X10, the current ISO 21287 ACE version: swap the P for an E and you get the same 20 mm bore, 10 mm stroke and force class in a short compact body. The ACP is DIN-standard, so confirm the ISO 21287 mounting dimensions against your fixture before swapping, and re-check FA/FB flange or LB foot hole patterns.
