This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACED20X75S, 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 ACPD20X75S
The AirTAC ACPD Double Rod Compact Cylinder ACPD20X75S is a double acting, double rod DIN-standard tight/compact air cylinder with a Ø20mm bore and 75mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACED20X75S (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPD Double Rod Compact Cylinder ACPD20X75S
Double acting with a rod exiting both covers, the ACPD20X75S is a DIN-standard compact cylinder that delivers 117.8 N in each direction at 0.5 MPa (164.9 N at 0.7 MPa), because both strokes work on the rod-side area. The through-rod resists rotation and light side load, gives a symmetric mount, and leaves the back-end rod free to carry a sensor flag. A fixed TPU bumper sits at each end, and speed spans 30-500 mm/s.
The hard-anodized aluminium body with an S45C hard-chrome rod saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight jigs and guarding. This unit carries the optional -S magnet, so CMSE / DMSE reed or solid-state switches can be fitted for end-position sensing. Note the ACPD family is discontinued: the current-production direct is the ACED20X75, and buyers should confirm ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACED20X75S (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).

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).
Where the Airtac ACPD Double Rod Compact Cylinder ACPD20X75S Is Used
Push-pull fixture clamping
The equal 117.8 N force in both directions lets one cylinder clamp a machined aluminium bracket and then eject it, with the 75 mm stroke clearing the fixture pocket.
Position-flag conveyor stop
With the -S magnet driving CMSE switches, the through-rod carries a flag at the rear so a bottling-line gate reports extend and retract without extra hardware.
Lab slide actuation
A compact analytical instrument slide needs about 6 kg of vertical lift and a symmetric mount; the short body fits where a full-length profile cylinder cannot.
Replacing the Airtac ACPD Double Rod Compact Cylinder ACPD20X75S with the ACED20X75S
At 75 mm the stroke sits inside the 100 mm standard limit for the 20 mm bore, so no made-to-order build is needed. If 117.8 N per side is marginal, step up to the 25 mm bore for 206.2 N at 0.5 MPa; if the load is light, the 16 mm bore gives 75.4 N. The female M6x1.0 rod thread suits standard I/Y knuckles, and FA/FB flange or LB foot brackets bolt to the same face. A plain double-rod cylinder will not hold position when air is lost - add a rod lock or pilot check for a held load. Order the ACED20X75 as the current replacement.
Replacement checklist
- ✓ Current-production ACE → ACED20X75S
- ✓ 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 ACPD20X75S FAQ
Force is equal both ways because the double rod leaves only rod-side area: 117.8 N at 0.5 MPa, 164.9 N at 0.7 MPa, and up to 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 pressure, air filtered to 40 um, speed 30-500 mm/s, and temperature -20 to +70 C.
The ISO 21287-class short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, with a fixed TPU bumper at each end. This model carries the optional -S magnet, so CMSE / DMSE switches can be mounted. It is discontinued; the ACED20X75 is the current direct - confirm ISO 21287 mounting dimensions before swapping.
