This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACED20X5B, 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 ACPD20X5B
The AirTAC ACPD Double Rod Compact Cylinder ACPD20X5B is a double acting, double rod DIN-standard tight/compact air cylinder with a Ø20mm bore and 5mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACED20X5B (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPD Double Rod Compact Cylinder ACPD20X5B
Double acting with a rod exiting both covers, the ACPD20X5B 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 5 mm stroke suits tiny clamp or eject moves, and the male rod thread (B code) bolts straight to your tooling. Its short ISO 21287-class body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it fits inside tight guards and slide fixtures.
The through-rod resists rotation and light side load, and the rear rod can carry a sensor flag on a mirrored mount. A fixed TPU bumper sits at each end to soften end-of-travel contact. Note there is no magnet fitted on this code; the optional -S version enables CMSE / DMSE switches. This model is discontinued - the current-production direct is ACED20X5, so confirm ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACED20X5B (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 ACPD20X5B Is Used
Micro clamp fixture
A 5 mm stroke with 117.8 N per side clamps small aluminium brackets in an electronics assembly jig without disturbing neighboring stations.
Pin eject on a slide
The rear rod drives a mirrored flag so a CMSE switch (with the -S magnet) confirms eject position on a short-stamp die slide.
Lab pusher station
At 0.7 MPa the 164.9 N both-ways force pushes sample trays 5 mm into a test nest, and the through-rod keeps the pusher square.
Replacing the Airtac ACPD Double Rod Compact Cylinder ACPD20X5B with the ACED20X5B
For a 5 mm stroke around 117.8 N per side, bore 20 is the match; step down to bore 16 (75.4 N at 0.5 MPa) for lighter eject pins or up to bore 25 (206.2 N) for heavier clamps. Remember the piston drifts when air is lost - add a rod lock or pilot check if the load must stay put. FA/FB flange and LB foot mountings bolt to the standard face, and the ACED20X5 is the current replacement to quote.
Replacement checklist
- ✓ Current-production ACE → ACED20X5B
- ✓ 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 ACPD20X5B FAQ
It is double acting with a double rod, so output is equal both ways: 117.8 N at 0.5 MPa and 164.9 N at 0.7 MPa on each stroke (rod-side area). Peak at 1.0 MPa is 24.0 kgf. Operating range is 0.15-1.0 MPa (22-145 psi), proof 1.5 MPa (215 psi), speed 30-500 mm/s, air filtered to 40 um.
Sensors need the optional -S magnet code; this ACPD20X5B has no magnet, so order ACPD20X5BS for CMSE / DMSE switches. The ACPD family is discontinued - the current-production replacement is ACED20X5 in the same bore, stroke and force class. Confirm the ISO 21287 mounting dimensions before you swap.
