This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACED20X120B, 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 ACPD20X120B
The AirTAC ACPD Double Rod Compact Cylinder ACPD20X120B is a double acting, double rod DIN-standard tight/compact air cylinder with a Ø20mm bore and 120mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACED20X120B (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPD Double Rod Compact Cylinder ACPD20X120B
A double acting compact cylinder with a rod leaving both covers, the ACPD20X120B delivers 117.8 N in either direction at 0.5 MPa because both strokes work on the rod-side area. The through-rod resists rotation and light side load, gives a symmetric mount, and the rear rod can carry a sensor flag. The 120 mm stroke is longer than the 100 mm standard maximum for bore 20, so it is a made-to-order build. This model is discontinued; the current-production replacement is the ACED20X120.
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 gantries. A fixed TPU bumper sits at each end, the male rod thread (B code) suits external nuts and knuckles, and the port is M5x0.8. Running on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi), it cycles at 30-500 mm/s.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACED20X120B (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 ACPD20X120B Is Used
Reciprocating test fixture
The through-rod drives a small electronics test head from either cover, giving equal 117.8 N press and return at 0.5 MPa without a return spring.
Flag-driven position sensing
The rear rod carries a flag past a switch on a packaging counting station; order the -S magnet version to enable CMSE or DMSE switches.
Compact clamping bridge
With about 50% shorter body than an ISO 15552 profile cylinder, the 120 mm made-to-order stroke clamps PCB fixtures inside a low guard envelope.
Replacing the Airtac ACPD Double Rod Compact Cylinder ACPD20X120B with the ACED20X120B
At 117.8 N per side at 0.5 MPa this bore 20 unit sits between the 16 mm bore (75.4 N) and the 25 mm bore (206.2 N). If your part weight exceeds about 6 kg on a vertical lift, step up to bore 25. The through-rod suits symmetric tooling and sensor-flag mounts, but the piston will drift if air is lost, so add a rod lock or pilot check for held loads. This version has no magnet; order the -S code if you later need CMSE or DMSE switches. For new projects, specify the ACED20X120 and confirm the ISO 21287 mounting dimensions before swapping.
Replacement checklist
- ✓ Current-production ACE → ACED20X120B
- ✓ 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 ACPD20X120B FAQ
Yes, equal both ways because a rod exits each cover and both strokes use the rod-side area: 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 120 mm stroke is a made-to-order length above the 100 mm standard maximum for bore 20.
This model is discontinued. The current direct is the ACED20X120, the ISO 21287 successor in the same bore, stroke and force class. Because the ACP series is DIN-standard, confirm the ISO 21287 mounting dimensions and the M6x1.0 rod-end hardware against your fixture before ordering.
