This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACED20X70SB, 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 ACPD20X70SB
The AirTAC ACPD Double Rod Compact Cylinder ACPD20X70SB is a double acting, double rod DIN-standard tight/compact air cylinder with a Ø20mm bore and 70mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACED20X70SB (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPD Double Rod Compact Cylinder ACPD20X70SB
A double acting, double-rod compact cylinder, the ACPD20X70SB pushes a 20 mm bore through a 70 mm stroke with a rod leaving both covers. Because each side works on the rod-side area, output is identical in either direction: 117.8 N at 0.5 MPa and 164.9 N at 0.7 MPa. The male rod thread (B code) suits threaded rod accessories, and the optional -S magnet this model carries lets CMSE or DMSE switches report end positions. AirTAC has discontinued the ACPD family; the current-production direct is ACED20X70.
The short ISO 21287-class body saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight fixtures, guarding and gantries. A hard-anodized aluminium body carries an S45C hard-chrome rod, fixed TPU bumpers sit at both ends, and speed runs 30-500 mm/s on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi).

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACED20X70SB (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 ACPD20X70SB Is Used
Fixture clamping on CNC pallets
The 117.8 N symmetric push-pull clamps small aluminium brackets from either side in a machining fixture, and the 70 mm stroke clears part loading.
Position-flagged test station
With the -S magnet fitted, CMSE or DMSE switches confirm end-of-stroke on a lab press slide cycling at 30-500 mm/s.
Replacing the Airtac ACPD Double Rod Compact Cylinder ACPD20X70SB with the ACED20X70SB
At 117.8 N per direction at 0.5 MPa, the 20 mm bore suits light clamping and transfer tasks; step down to the 16 mm bore (75.4 N) for smaller loads or up to the 25 mm bore (206.2 N) when more force is needed. The 70 mm stroke sits inside the 100 mm maximum standard stroke for this bore. The through-rod resists rotation and side load and gives a symmetric mount, and the rear rod can carry a sensor flag. FA/FB flange or LB foot mounting bolts to the standard face. Note that a plain double-rod cylinder drifts when air is lost, so add a rod lock or pilot check for held loads. This model is discontinued - order ACED20X70 and confirm the ISO 21287 mounting dimensions before swapping, since the ACP is DIN-standard.
Replacement checklist
- ✓ Current-production ACE → ACED20X70SB
- ✓ 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 ACPD20X70SB FAQ
Output is equal both ways because the double rod leaves both covers working on the rod-side area: 117.8 N at 0.5 MPa, 164.9 N at 0.7 MPa, and up to 24.0 kgf at 1.0 MPa. Operating pressure is 0.15-1.0 MPa (22-145 psi) with 1.5 MPa (215 psi) proof pressure, speed 30-500 mm/s, and the port is M5x0.8.
The short ISO 21287-class body saves about 50% of the mounting length of an ISO 15552 profile cylinder, with a hard-anodized aluminium body, S45C hard-chrome rod and fixed TPU bumpers at both ends. The ACPD is discontinued; ACED20X70 is the current direct in the same bore, stroke and force class - confirm the ISO 21287 mounting dimensions before swapping.
