This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACED20X65B, 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 ACPD20X65B
The AirTAC ACPD Double Rod Compact Cylinder ACPD20X65B is a double acting, double rod DIN-standard tight/compact air cylinder with a Ø20mm bore and 65mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACED20X65B (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPD Double Rod Compact Cylinder ACPD20X65B
A double acting compact cylinder with a rod leaving both covers, the discontinued ACPD20X65B pushes and pulls with identical output: 117.8 N at 0.5 MPa and 164.9 N at 0.7 MPa in either direction, because both strokes work on the rod-side area of the 20 mm bore. The 10 mm through-rod resists rotation and side load, gives a symmetric mounting point at each end, and the rear rod can carry a sensor flag. A fixed TPU bumper sits at both covers, speed spans 30-500 mm/s, and pressure runs 0.15-1.0 MPa (22-145 psi) with a 1.5 MPa (215 psi) proof rating.
The hard-anodized aluminium body keeps the mounting length roughly 50% shorter than an ISO 15552 profile cylinder, so this 65 mm stroke unit slots into tight fixtures, slides and gantries. Note there is no magnet fitted: order the optional -S code if you need CMSE or DMSE switch sensing. This model is discontinued; the current direct is ACED20X65 in the ISO 21287 series - confirm mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACED20X65B (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 ACPD20X65B Is Used
Symmetric small-part clamping
The equal 117.8 N force in both directions lets a fixture clamp and release a machined bracket with identical grip, using the male M6x1.0 threads on both rods.
Push-pull tray transfer
A packaging line slides 5-6 kg trays between two stations; the through-rod on the far side carries the guide bracket while the near rod does the work at 30-500 mm/s.
Indexing with position feedback
Order the -S option to add a magnet, then fit CMSE or DMSE switches on the body to confirm end positions of a rotary dial indexer on an assembly bench.
Replacing the Airtac ACPD Double Rod Compact Cylinder ACPD20X65B with the ACED20X65B
Size around the 117.8 N both-ways output at 0.5 MPa: step down to ACPD16 (75.4 N) for lighter tooling or up to ACPD25 (206.2 N) if your jig needs more grip. The 65 mm stroke sits inside the 100 mm standard limit for bore 20, so no made-to-order build is required. The B code gives a male M6x1.0 rod thread at each end and the port is M5x0.8. Remember the piston drifts when air is lost - add a rod lock or pilot check if the load must stay put. For new designs, order the ACED20X65 instead, as this ACPD model is discontinued.
Replacement checklist
- ✓ Current-production ACE → ACED20X65B
- ✓ 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 ACPD20X65B 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, with a maximum of 24.0 kgf at 1.0 MPa. Both strokes use the rod-side area of the 20 mm bore, so push never exceeds pull. Operating range is 0.15-1.0 MPa (22-145 psi).
The hard-anodized aluminium body follows the short ISO 21287-class format, cutting mounting length by about 50% versus an ISO 15552 profile cylinder, with a fixed TPU bumper at each end and FA/FB flange or LB foot mounting. The ACPD20X65B is discontinued - the current-production replacement is ACED20X65, so confirm the ISO 21287 mounting dimensions before you swap.
