This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACED20X5, 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 ACPD20X5
The AirTAC ACPD Double Rod Compact Cylinder ACPD20X5 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 ACED20X5 (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPD Double Rod Compact Cylinder ACPD20X5
A double acting compact cylinder with a rod leaving both covers, the ACPD20X5 delivers 117.8 N in each direction at 0.5 MPa because both strokes work on the rod-side area of the 20 mm bore. The 5 mm stroke suits tiny positioning moves, and the through-rod resists rotation and side load while giving a symmetric mount and a rear rod that can carry a sensor flag. At 0.7 MPa the same force rises to 164.9 N both ways, with a peak of 24.0 kgf at 1.0 MPa.
The hard-anodized aluminium body with an S45C hard-chrome rod keeps the short ISO 21287-class build roughly 50% shorter in mounting length than an ISO 15552 profile cylinder, so it slots into cramped fixtures and guarding. A fixed TPU bumper sits at each end, and speed runs 30-500 mm/s at 0.15-1.0 MPa (22-145 psi). Note this model is discontinued: the current-production direct is the ACED20X5, and buyers should confirm the ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACED20X5 (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 ACPD20X5 Is Used
Micro part ejection
The 5 mm stroke and 117.8 N output both ways make this cylinder a fit for nudging small machined or molded parts off a fixture nest on a CNC secondary-operation line.
Push-to-present tray indexing
A short indexing push on electronics assembly benches, where the through-rod carries a flag for a proximity sensor and the compact body fits under a low guard.
Lab sample press
Light pressing of vials or test coupons in analytical equipment, with about 6 kg of safe vertical lift capacity and a fixed TPU bumper to soften each end of the 5 mm move.
Replacing the Airtac ACPD Double Rod Compact Cylinder ACPD20X5 with the ACED20X5
For a 5 mm stroke at this force level, the 20 mm bore gives 117.8 N both ways at 0.5 MPa; step down to the 16 mm bore (75.4 N) for lighter clamping or up to the 25 mm bore (206.2 N) if the load grows. Like any plain double-rod cylinder it will not hold position when air is lost, so add a rod lock or pilot check for a held load. Mount via FA/FB flange or LB foot, and remember the magnet is the optional -S code - without it no CMSE or DMSE switch can be fitted. Order the ACED20X5 as the current replacement and verify ISO 21287 dimensions.
Replacement checklist
- ✓ Current-production ACE → ACED20X5
- ✓ 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 ACPD20X5 FAQ
Yes - it is a double-rod cylinder, so force is equal both ways: 117.8 N at 0.5 MPa and 164.9 N at 0.7 MPa on the rod-side area of the 20 mm bore, peaking at 24.0 kgf at 1.0 MPa. Stroke is 5 mm, rod is 10 mm with an M6x1.0 female thread, and the port is M5x0.8. Operating range is 0.15-1.0 MPa (22-145 psi) at 30-500 mm/s.
Only if you order the optional -S magnet code - this model (no S) has no magnet, so no CMSE or DMSE reed or solid-state switch can be detected. The ACPD family is discontinued; the current-production direct is the ACED20X5 (ISO 21287, same bore, stroke and force class). Confirm the ISO 21287 mounting dimensions against your fixture before swapping.
