This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACED20X100B, 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 ACPD20X100B
The AirTAC ACPD Double Rod Compact Cylinder ACPD20X100B is a double acting, double rod DIN-standard tight/compact air cylinder with a Ø20mm bore and 100mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACED20X100B (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPD Double Rod Compact Cylinder ACPD20X100B
A double acting compact cylinder with a rod through both covers, the ACPD20X100B delivers 117.8 N in either direction at 0.5 MPa because both strokes work on the rod-side area. The 20 mm bore carries a 10 mm rod, the male thread on each end (the B code) bolts straight to your tooling, and the fixed TPU bumper decelerates the piston at both ends. Its short ISO 21287-class body saves about 50% of the mounting length of an ISO 15552 profile cylinder, which is why it fits tight fixtures and guarding.
This model is discontinued; the current-production direct is the ACED20X100, which matches the same bore, stroke and force class - confirm the ISO 21287 mounting dimensions before swapping. Speed range is 30-500 mm/s, pressure 0.15-1.0 MPa (22-145 psi), and the optional -S magnet enables CMSE / DMSE switches; without -S there is no magnet fitted.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACED20X100B (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 ACPD20X100B Is Used
Reciprocating transfer slide
The through-rod gives an identical 117.8 N pull and push at 0.5 MPa, so a pick-and-place slide on a small assembly machine moves parts at the same speed in both directions.
Flag-driven position sensing
The rear rod can carry a sensor flag past a CMSE or DMSE switch (order the -S magnet code), giving end-of-stroke confirmation on a 100 mm stroke test fixture.
Symmetric clamping press
Equal force both ways suits a small bench press or crimping jig that must press and retract with the same 164.9 N at 0.7 MPa, with the male thread taking a forming tool.
Replacing the Airtac ACPD Double Rod Compact Cylinder ACPD20X100B with the ACED20X100B
At 117.8 N both ways, bore 20 sits between bore 16 (75.4 N at 0.5 MPa) and bore 25 (206.2 N at 0.5 MPa) - step up if your jig needs the extra margin, down if the load is light. The 100 mm stroke is the maximum standard stroke for this bore, so no made-to-order build is needed. Remember that a plain double-rod cylinder drifts when air is lost; add a rod lock or pilot check if the load must stay put. Mounting options include FA/FB flange, LB foot, CA/CB clevis, CR, SDB pivot and FTC brackets, and the male rod thread (B) suits knuckle joints. Order the ACED20X100 for new projects.
Replacement checklist
- ✓ Current-production ACE → ACED20X100B
- ✓ 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 ACPD20X100B FAQ
Because a rod exits both covers, force is equal in both directions: 117.8 N at 0.5 MPa and 164.9 N at 0.7 MPa, on the rod-side area. Peak output at 1.0 MPa is 24.0 kgf. Operating pressure is 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), speed 30-500 mm/s, port M5x0.8, rod 10 mm with male thread.
It is a compact hard-anodized aluminium cylinder with an S45C hard-chrome rod, a fixed TPU bumper at each end, and a short body that saves about 50% of the mounting length of an ISO 15552 profile cylinder. The ACPD family is discontinued; the ACED20X100 is the current ISO 21287 direct with the same bore, stroke and force class - verify mounting dimensions before ordering.
