This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACED25X20SB, 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 ACPD25X20SB
The AirTAC ACPD Double Rod Compact Cylinder ACPD25X20SB is a double acting, double rod DIN-standard tight/compact air cylinder with a Ø25mm bore and 20mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACED25X20SB (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPD Double Rod Compact Cylinder ACPD25X20SB
A double acting compact cylinder with a rod leaving both covers, the AirTAC ACPD25X20SB delivers 206.2 N in each direction at 0.5 MPa because both strokes work on the rod-side area of the 25 mm bore. The through-rod resists rotation and light side load, and the rear rod can carry a sensor flag or a second tooling plate. Stroke is 20 mm, the male rod thread (B code) suits external nuts and knuckles, and the fixed TPU bumper pads both end faces.
The short ISO 21287-class body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight jigs and guarding where a full-length body will not fit. FA/FB flange and LB foot brackets bolt to the standard face, and this model carries the optional -S magnet so CMSE / DMSE switches can be fitted. Note the ACPD family is discontinued: the current-production direct is ACED25X20, so confirm the ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACED25X20SB (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 (Ø25mm)
| Pressure | Force (both ways) |
|---|---|
| 0.5 MPa | 206 N |
| 0.7 MPa | 289 N |
| Max (@1.0 MPa) | 42 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 ACPD25X20SB Is Used
Symmetric fixture clamping
The 206.2 N equal force in both directions lets one ACPD25X20SB clamp and release a machined housing in a drilling fixture without re-plumbing for unequal pull.
Flag-driven stroke sensing
With the -S magnet already fitted, a CMSE switch on the rear rod confirms the 20 mm advance of a solder-paste print head before the next cycle starts.
Push-pull gate actuation
A packaging line slide gate gets identical 288.6 N at 0.7 MPa opening and closing from the through-rod, with the back rod balancing the mount.
Replacing the Airtac ACPD Double Rod Compact Cylinder ACPD25X20SB with the ACED25X20SB
At 206.2 N per side (0.5 MPa) this 25 mm bore suits clamping and positioning loads up to roughly 12 kgf of real work; step down to the 20 mm bore at 117.8 N for lighter fixtures or up to the 32 mm bore at 345.6 N when you need more grip. The 20 mm stroke sits well inside the 150 mm standard range for this bore. Remember a plain double-rod cylinder drifts when air is lost - add a rod lock or pilot check if the load must stay put. If you need position feedback, this unit already carries the -S magnet for CMSE / DMSE switches. Since ACPD is discontinued, order ACED25X20 as the current replacement and verify the ISO 21287 hole pattern first.
Replacement checklist
- ✓ Current-production ACE → ACED25X20SB
- ✓ 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 ACPD25X20SB FAQ
Yes - the double-rod design exposes the rod-side area on both strokes, so force is equal either way: 206.2 N at 0.5 MPa and 288.6 N at 0.7 MPa, with a maximum of 42.0 kgf at 1.0 MPa. Operating range is 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), speed 30-500 mm/s, and the bore takes an M5x0.8 port.
The hard-anodized aluminium body follows the short ISO 21287-class format, cutting about 50% of the mounting length of an ISO 15552 profile cylinder, with FA/FB flange or LB foot mounting and fixed TPU bumpers at both ends. ACPD is no longer in production: the current direct is ACED25X20 (same 25 mm bore, 20 mm stroke and force class), so confirm the ISO 21287 mounting dimensions before you swap.
