This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACED20X50B, 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 ACPD20X50B
The AirTAC ACPD Double Rod Compact Cylinder ACPD20X50B is a double acting, double rod DIN-standard tight/compact air cylinder with a Ø20mm bore and 50mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACED20X50B (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPD Double Rod Compact Cylinder ACPD20X50B
A double acting compact cylinder with a rod leaving both covers, the ACPD20X50B delivers 117.8 N at 0.5 MPa and 164.9 N at 0.7 MPa in either direction, since both strokes work on the rod-side area. The through-rod resists rotation and light side load, gives a symmetric mounting face, and the rear rod can carry a sensor flag. A fixed TPU bumper sits at each end and speeds run from 30 to 500 mm/s.
The hard-anodized aluminium body keeps the mounting length roughly 50% shorter than an ISO 15552 profile cylinder, so it slots into tight jigs and guarding where a full-length body will not fit. Note this model is discontinued: the current-production direct is the ISO 21287 ACED20X50, so confirm mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACED20X50B (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 ACPD20X50B Is Used
Reciprocating parts transfer
The through-rod lets a small fixture be driven from either end on a pick-and-place slide, with equal 117.8 N force on extend and retract at 0.5 MPa.
Flag-driven position checking
The rear rod carries a proximity flag so a PLC can confirm stroke completion on a 50 mm test-station actuator, using CMSE or DMSE switches when the -S magnet is ordered.
Light press and forming jig
With about 70 N of usable work force, the bore 20 body suits staking or locating pins in electronics assembly fixtures where space is tight.
Replacing the Airtac ACPD Double Rod Compact Cylinder ACPD20X50B with the ACED20X50B
At 117.8 N per side, bore 20 suits light clamping and transfer tasks; step down to bore 16 (75.4 N) for smaller loads or up to bore 25 (206.2 N) when more force is needed. Like any plain double-rod cylinder it drifts when air is lost, so add a rod lock or pilot check for a held load. The 50 mm stroke sits well inside the 100 mm standard range for this bore. This unit has no magnet fitted; order the -S code if you need CMSE / DMSE switch positions. For new projects, specify the ACED20X50 instead.
Replacement checklist
- ✓ Current-production ACE → ACED20X50B
- ✓ 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 ACPD20X50B FAQ
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, with a maximum of 24.0 kgf at 1.0 MPa. Operating range is 0.15-1.0 MPa (22-145 psi) and proof pressure is 1.5 MPa (215 psi).
The hard-anodized aluminium body is an ISO 21287-class short build, saving about 50% of the mounting length of an ISO 15552 profile cylinder, with FA/FB flange or LB foot brackets and a fixed TPU bumper at each end. The ACPD family is discontinued; the ACED20X50 is the current direct, so verify ISO 21287 mounting dimensions before ordering.
